CHANGELOG

The following tip changes can be tested by building VictoriaMetrics components from the latest commits according to the following docs:

tip

  • FEATURE: MetricsQL: add support for numbers with underscore delimiters such as 1_234_567_890 and 1.234_567_890. These numbers are easier to read than 1234567890 and 1.234567890.

  • FEATURE: vmbackup: add support for server-side copy of existing backups. See these docs for details.

  • FEATURE: vmui: add the option to see the latest 25 queries. See this issue.

  • FEATURE: vmagent: add ability to set member num label for all the metrics scraped by a particular vmagent instance in a cluster of vmagents via -promscrape.cluster.memberLabel command-line flag. See these docs and this issue.

  • FEATURE: vmagent: do not log unexpected EOF when reading incoming metrics, since this error is expected and is handled during metrics' parsing. This reduces the amounts of noisy logs. See this issue.

  • FEATURE: vmagent: retry failed write request on the closed connection immediately, without waiting for backoff. This should improve data delivery speed and reduce amount of error logs emitted by vmagent when using idle connections. See related issue.

  • FEATURE: vmagent: reduces load on Kubernetes control plane during initial service discovery. See this issue for details.

  • FEATURE: VictoriaMetrics cluster: reduce the maximum recovery time at vmselect and vminsert when some of vmstorage nodes become unavailable because of networking issues from 60 seconds to 3 seconds by default. The recovery time can be tuned at vmselect and vminsert nodes with -vmstorageUserTimeout command-line flag if needed. Thanks to @wjordan for the pull request.

  • FEATURE: vmui: add Prometheus data support to the "Explore cardinality" page. See this issue for details.

  • FEATURE: vmui: make the warning message more noticeable for text fields. See this issue.

  • FEATURE: vmui: add button for auto-formatting PromQL/MetricsQL queries. See this issue. Thanks to @aramattamara for the pull request.

  • FEATURE: vmui: improve accessibility score to 100 according to Google's Lighthouse tests.

  • FEATURE: vmui: organize min, max, median values on the chart legend and tooltips for better visibility.

  • FEATURE: dashboards: provide copies of Grafana dashboards alternated with VictoriaMetrics datasource at dashboards/vm.

  • FEATURE: vmauth: added ability to set, override and clear request and response headers on a per-user and per-path basis. See this issue and these docs for details.

  • BUGFIX: Official Grafana dashboards for VictoriaMetrics: fix display of ingested rows rate for Samples ingested/s and Samples rate panels for vmagent's dasbhoard. Previously, not all ingested protocols were accounted in these panels. An extra panel Rows rate was added to Ingestion section to display the split for rows ingested rate by protocol.

v1.93.3

Released at 2023-09-02

v1.93.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes. The v1.93.x line will be supported for at least 12 months since v1.93.0 release

  • BUGFIX: vminsert: properly close broken vmstorage connection during read-only state checks at vmstorage. Previously it wasn't properly closed, which prevents restoring vmstorage node from read-only mode. See this issue.
  • BUGFIX: vmstorage: prevent from breaking vmselect -> vmstorage RPC communication when vmstorage returns an empty label name at /api/v1/labels request. See this issue.

v1.93.2

Released at 2023-09-01

v1.93.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes. The v1.93.x line will be supported for at least 12 months since v1.93.0 release

  • BUGFIX: build: fix Docker builds for old Docker releases. See this issue.
  • BUGFIX: vmagent: consistently set User-Agent header to vm_promscrape during scraping with enabled or disabled stream parsing mode. See this issue.
  • BUGFIX: vmagent: consistently set timeout for scraping with enabled or disabled stream parsing mode. See this issue.
  • BUGFIX: vmalert: correctly re-use HTTP request object on EOF retries when querying the configured datasource. Previously, there was a small chance that query retry wouldn't succeed.
  • BUGFIX: vmselect: correctly handle requests with /select/multitenant prefix. Such requests must be rejected since vmselect does not support multitenancy endpoint. Previously, such requests were causing panic. See this issue.
  • BUGFIX: vminsert: properly check for read-only state at vmstorage. Previously it wasn't properly checked, which could lead to increased resource usage and data ingestion slowdown when some of vmstorage nodes are in read-only mode. See this issue.

v1.93.1

Released at 2023-08-23

v1.93.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes. The v1.93.x line will be supported for at least 12 months since v1.93.0 release

  • BUGFIX: prevent from possible data loss during indexdb rotation. See this issue for details.
  • BUGFIX: do not allow starting VictoriaMetrics components with improperly set boolean command-line flags in the form -boolFlagName value, since this leads to silent incomplete flags' parsing. This form should be replaced with -boolFlagName=value. See this issue.
  • BUGFIX: vmagent: properly set labels from -remoteWrite.label command-line flag just before sending samples to the configured -remoteWrite.url according to these docs. Previously these labels were incorrectly set before the relabeling configured via -remoteWrite.urlRelabelConfigs and the stream aggregation configured via -remoteWrite.streamAggr.config, so these labels could be lost or incorrectly transformed before sending the samples to remote storage. The fix allows using -remoteWrite.label for identifying vmagent instances in cluster mode. See this issue and these docs for more details.
  • BUGFIX: remove DEBUG logging when parsing if filters inside relabeling rules and when parsing match filters inside stream aggregation rules.
  • BUGFIX: properly replace : chars in label names with _ when -usePromCompatibleNaming command-line flag is passed to vmagent, vminsert or single-node VictoriaMetrics. This addresses this comment.
  • BUGFIX: vmbackup: correctly check if specified -dst belongs to specified -storageDataPath. See this issue.
  • BUGFIX: vmctl: don't interrupt the migration process if no metrics were found for a specific tenant. See this issue.

v1.93.0

Released at 2023-08-12

It is recommended upgrading to VictoriaMetrics v1.93.1 because v1.93.0 contains a bug, which can lead to data loss because of incorrect indexdb rotation. See this issue for details.

v1.93.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes. The v1.93.x line will be supported for at least 12 months since v1.93.0 release

Update note: starting from this release, vmagent ignores timestamps provided by scrape targets by default - it associates scraped metrics with local timestamps instead. Set honor_timestamps: true in scrape configs if timestamps provided by scrape targets must be used instead. This change helps removing gaps for metrics collected from cadvisor such as container_memory_usage_bytes. This also improves data compression and query performance over metrics collected from cadvisor. See more details here.

  • SECURITY: upgrade Go builder from Go1.20.6 to Go1.21.0 in order to fix this issue.

  • SECURITY: upgrade base docker image (Alpine) from 3.18.2 to 3.18.3. See alpine 3.18.3 release notes.

  • FEATURE: MetricsQL: add share_eq_over_time(m[d], eq) function for calculating the share (in the range [0...1]) of raw samples on the given lookbehind window d, which are equal to eq. See this feature request. Thanks to @Damon07 for the pull request.

  • FEATURE: vmauth: allow configuring deadline for a backend to be excluded from the rotation on errors via -failTimeout cmd-line flag. This feature could be useful when it is expected for backends to be not available for significant periods of time. See this issue for details. Thanks to @SunKyu for the pull request.

  • FEATURE: vmalert: remove deprecated in v1.61.0 -rule.configCheckInterval command-line flag. Use -configCheckInterval command-line flag instead.

  • FEATURE: vmalert: remove support of deprecated web links of /api/v1/<groupID>/<alertID>/status form in favour of /api/v1/alerts?group_id=<>&alert_id=<> links. Links of /api/v1/<groupID>/<alertID>/status form were deprecated in v1.79.0. See this issue for details.

  • FEATURE: vmctl: allow disabling binary export API protocol via -vm-native-disable-binary-protocol cmd-line flag when migrating data from VictoriaMetrics. Disabling binary protocol can be useful for deduplication of the exported data before ingestion. For this, deduplication need to be configured at -vm-native-src-addr side and -vm-native-disable-binary-protocol should be set on vmctl side.

  • FEATURE: vmctl: add support of week step for time-based chunking migration. See this issue.

  • FEATURE: vmctl: allow specifying custom full url at --remote-read-src-addr command-line flag if --remote-read-disable-path-append command-line flag is set. This allows importing data from urls, which do not end with /api/v1/read. For example, from Promscale. See this issue.

  • FEATURE: vmui: add warning in query field of vmui for partial data responses. See this issue.

  • FEATURE: vmui: allow displaying the full error message on click for trimmed error messages in vmui. See this issue.

  • FEATURE: Official Grafana dashboards for VictoriaMetrics: add Concurrent inserts panel to vmagent's dasbhoard. The new panel supposed to show whether the number of concurrent inserts processed by vmagent isn't reaching the limit.

  • FEATURE: Official Grafana dashboards for VictoriaMetrics: add panels for absolute Mem and CPU usage by vmalert. See related issue here.

  • FEATURE: Official Grafana dashboards for VictoriaMetrics: correctly calculate Bytes per point value for single-server and cluster VM dashboards. Before, the calculation mistakenly accounted for the number of entries in indexdb in denominator, which could have shown lower values than expected.

  • FEATURE: Alerting rules for VictoriaMetrics: ConcurrentFlushesHitTheLimit alerting rule was moved from single-server and cluster alerts to the list of "health" alerts as it could be related to many VictoriaMetrics components.

  • BUGFIX: storage: properly set next retention time for indexDB. Previously it may enter into endless retention loop. See this issue for details.

  • BUGFIX: vmagent: return human readable error if opentelemetry has json encoding. Follow-up after PR.

  • BUGFIX: vmagent: properly validate scheme for proxy_url field at the scrape config. See this issue for details.

  • BUGFIX: vmagent: properly apply if filters during relabeling. Previously the if filter could improperly work. See this issue and this pull request.

  • BUGFIX: vmagent: use local scrape timestamps for the scraped metrics unless honor_timestamps: true option is explicitly set at scrape_config. This fixes gaps for metrics collected from cadvisor or similar exporters, which export metrics with invalid timestamps. See this issue and this comment for details. The issue has been introduced in v1.68.0.

  • BUGFIX: vmagent: fixes runtime panic at OpenTelemetry parser. Opentelemetry format allows histograms without sum fields. Such histogram converted as counter with _count suffix. See this issue.

  • BUGFIX: vmagent: keep unmatched series at stream aggregation when -remoteWrite.streamAggr.dropInput is set to false to match intended behaviour introduced at v1.92.0. See this issue.

  • BUGFIX: vmalert: properly set vmalert_config_last_reload_successful value on configuration updates or rollbacks. The bug was introduced in v1.92.0 in this PR.

  • BUGFIX: vmalert: fix vmalert_remotewrite_send_duration_seconds_total value, before it didn't count in the real time spending on remote write requests. See this pr for details.

  • BUGFIX: vmbackupmanager: fix panic when creating a backup to a local filesystem on Windows. See this issue.

  • BUGFIX: vmui: properly handle client address with X-Forwarded-For part at the Active queries page. See this comment.

  • BUGFIX: MetricsQL: prevent from panic when the lookbehind window in square brackets of rollup function is parsed into negative value. See this issue.

v1.92.1

Released at 2023-07-28

v1.92.0

Released at 2023-07-27

Update note: this release contains backwards-incompatible change to indexdb, so rolling back to the previous versions of VictoriaMetrics may result in partial data loss of entries in indexdb.

Update note: starting from this release, stream aggregation writes the following samples to the configured remote storage by default:

  • aggregated samples;
  • the original input samples, which match zero match options from the provided config.

Previously only aggregated samples were written to the storage by default. The previous behavior can be restored in the following ways:

  • by passing -streamAggr.dropInput command-line flag to single-node VictoriaMetrics;
  • by passing -remoteWrite.streamAggr.dropInput command-line flag per each configured -remoteWrite.streamAggr.config at vmagent.

  • SECURITY: upgrade base docker image (alpine) from 3.18.0 to 3.18.2. See alpine 3.18.2 release notes.

  • SECURITY: upgrade Go builder from Go1.20.5 to Go1.20.6. See the list of issues addressed in Go1.20.6.

  • FEATURE: reduce memory usage by up to 5x for setups with high churn rate and long retention. See the description for this change and this issue for details.

  • FEATURE: reduce spikes in CPU and disk IO usage during indexdb rotation (aka inverted index), which is performed once per -retentionPeriod. The new algorithm gradually pre-populates newly created indexdb during the last hour before the rotation. The number of pre-populated series in the newly created indexdb can be monitored via vm_timeseries_precreated_total metric. This should resolve this issue.

  • FEATURE: MetricsQL: allow selecting time series matching at least one of multiple or filters. For example, {env="prod",job="a" or env="dev",job="b"} selects series with either {env="prod",job="a"} or {env="dev",job="b"} labels. This functionality allows passing the selected series to rollup functions without the need to use subqueries. See these docs.

  • FEATURE: MetricsQL: add ability to preserve metric names for binary operation results via keep_metric_names modifier. For example, ({__name__=~"foo|bar"} / 10) keep_metric_names leaves foo and bar metric names in division results. See these docs. This helps to address issues like this one.

  • FEATURE: MetricsQL: add ability to copy all the labels from one side of many-to-one operations by specifying * inside group_left() or group_right(). Also allow adding a prefix for copied label names via group_left(*) prefix "..." syntax. For example, the following query copies Kubernetes namespace labels to kube_pod_info series and adds ns_ prefix for the copied label names: kube_pod_info * on(namespace) group_left(*) prefix "ns_" kube_namespace_labels. The labels from on() list aren't prefixed. This feature resolves this and that questions at StackOverflow.

  • FEATURE: MetricsQL: add ability to specify durations via WITH templates. Examples:

    • WITH (w = 5m) m[w] is automatically transformed to m[5m]
    • WITH (f(window, step, off) = m[window:step] offset off) f(5m, 10s, 1h) is automatically transformed to m[5m:10s] offset 1h Thanks to @lujiajing1126 for the initial idea and implementation. See this feature request.
  • FEATURE: vmui: added a new page with the list of currently running queries. See this issue and these docs.

  • FEATURE: vmagent: add support for data ingestion via OpenTelemetry protocol. See these docs, this feature request and this pull request.

  • FEATURE: vmagent: allow sharding outgoing time series among the configured remote storage systems. This can be useful for building horizontally scalable stream aggregation, when samples for the same time series must be aggregated by the same vmagent instance at the second level. See these docs and this feature request for details.

  • FEATURE: vmagent: allow configuring staleness interval in stream aggregation config. See this issue for details.

  • FEATURE: vmagent: allow specifying a list of series selectors inside if option of relabeling rules. The corresponding relabeling rule is executed when at least a single series selector matches. See these docs.

  • FEATURE: stream aggregation: allow specifying a list of series selectors inside match option of stream aggregation configs. The input sample is aggregated when at least a single series selector matches. See this feature request.

  • FEATURE: stream aggregation: preserve input samples, which match zero match options from the configured aggregations. Previously all the input samples were dropped by default, so only the aggregated samples are written to the output storage. The previous behavior can be restored by passing -streamAggr.dropInput command-line flag to single-node VictoriaMetrics or by passing -remoteWrite.streamAggr.dropInput command-line flag to vmagent.

  • FEATURE: vmctl: add verbose output for docker installations or when TTY isn't available. See this issue.

  • FEATURE: vmctl: interrupt backoff retries when import process is cancelled. The change makes vmctl more responsive in case of errors during the import. See this pull request.

  • FEATURE: vmctl: update backoff policy on retries to reduce probability of overloading for source or destination databases. See this issue.

  • FEATURE: vmstorage: suppress "broken pipe" and "connection reset by peer" errors for search queries on vmstorage side. See this and this commits.

  • FEATURE: Official Grafana dashboards for VictoriaMetrics: add panel for tracking rate of syscalls while writing or reading from disk via process_io_(read|write)_syscalls_total metrics.

  • FEATURE: accept timestamps in milliseconds at start, end and time query args in Prometheus querying API. See these docs and this feature request.

  • FEATURE: vmalert: update retry policy for pushing data to -remoteWrite.url. By default, vmalert will make multiple retry attempts with exponential delay. The total time spent during retry attempts shouldn't exceed -remoteWrite.retryMaxTime (default is 30s). When retry time is exceeded vmalert drops the data dedicated for -remoteWrite.url. Before, vmalert dropped data after 5 retry attempts with 1s delay between attempts (not configurable). See -remoteWrite.retryMinInterval and -remoteWrite.retryMaxTime cmd-line flags.

  • FEATURE: vmalert: expose vmalert_remotewrite_send_duration_seconds_total counter, which can be used for determining high saturation of every connection to remote storage with an alerting query sum(rate(vmalert_remotewrite_send_duration_seconds_total[5m])) by(job, instance) > 0.9 * max(vmalert_remotewrite_concurrency) by(job, instance). This query triggers when a connection is saturated by more than 90%. This usually means that -remoteWrite.concurrency command-line flag must be increased in order to increase the number of concurrent writings into remote endpoint. See this feature request.

  • FEATUTE: vmalert: display the error message received during unsuccessful config reload in vmalert's UI. See this issue for details.

  • FEATUTE: vmalert: allow disabling of step param attached to instant queries. This might be useful for using vmalert with datasources that to not support this param, unlike VictoriaMetrics. See this issue for details.

  • FEATUTE: vmalert: support option for "blackholing" alerting notifications if -notifier.blackhole cmd-line flag is set. Enable this flag if you want vmalert to evaluate alerting rules without sending any notifications to external receivers (eg. alertmanager). See this issue for details. Thanks to @venkatbvc for the pull request.

  • FEATURE: vmalert: add unit test for alerting and recording rules, see more details here. Thanks to @Haleygo for the pull request.

  • FEATURE: vmalert: allow overriding default GET params for rules with graphite datasource type, in the same way as it happens for prometheus type. See this issue.

  • FEATUTE: vmalert: support keep_firing_for field for alerting rules. See docs updated here and this issue. Thanks to @Haleygo for the pull request.

  • FEATURE: vmauth: expose vmauth_user_request_duration_seconds and vmauth_unauthorized_user_request_duration_seconds summary metrics for measuring requests latency per user.

  • FEATURE: vmbackup: show backup progress percentage in log during backup uploading. See this issue.

  • FEATURE: vmrestore: show restoring progress percentage in log during backup downloading. See this issue.

  • FEATURE: add ability to fine-tune Graphite API limits via the following command-line flags: -search.maxGraphiteTagKeys for limiting the number of tag keys returned from Graphite API for tags -search.maxGraphiteTagValues for limiting the number of tag values returned from Graphite API for tag values -search.maxGraphiteSeries for limiting the number of series (aka paths) returned from Graphite API for series See this issue.

  • BUGFIX: properly return series from /api/v1/series if it finds more than the limit series (limit is an optional query arg passed to this API). Previously the limit exceeded error error was returned in this case. See this issue.

  • BUGFIX: vmui: fix application routing issues and problems with manual URL changes. See this pull request and this issue.

  • BUGFIX: add validation for invalid partial RFC3339 timestamp formats in query and export APIs.

  • BUGFIX: vmctl: interrupt explore procedure in influx mode if vmctl found no numeric fields.

  • BUGFIX: vmctl: fix panic in case --remote-read-filter-time-start flag is not set for remote-read mode. This flag is now required to use remote-read mode. See this issue.

  • BUGFIX: vmctl: fix formatting issue, which could add superflouos s characters at the end of samples/s output during data migration. For example, it could write samples/ssssss. See this issue.

  • BUGFIX: vmalert: use RFC3339 time format in query args instead of unix timestamp for all issued queries to Prometheus-like datasources.

  • BUGFIX: vmalert: correctly calculate evaluation time for rules. Before, there was a low probability for discrepancy between actual time and rules evaluation time if evaluation interval was lower than the execution time for rules within the group.

  • BUGFIX: vmalert: reset evaluation timestamp after modifying group interval. Before, there could have latency on rule evaluation time.

  • BUGFIX: vmselect: fix timestamp alignment for Prometheus querying API if time argument is less than 10m from the beginning of Unix epoch.

  • BUGFIX: vmagent: close HTTP connections to service discovery servers when they are no longer needed. This should prevent from possible connection exhasution in some cases. See this issue.

  • BUGFIX: vmagent: do not show relabel debug links at the /targets page when vmagent runs with -promscrape.dropOriginalLabels command-line flag, since it has no the original labels needed for relabel debug. See this issue.

  • BUGFIX: vminsert: fixed decoding of label values with slash when accepting data via pushgateway protocol. This fixes Prometheus golang client compatibility. See this issue.

  • BUGFIX: MetricsQL: properly parse binary operations with reserved words on the right side such as foo + (on{bar="baz"}). Previously such queries could lead to panic. See this issue.

  • BUGFIX: Official Grafana dashboards for VictoriaMetrics: display cache usage for all components on panel Cache usage % by type for cluster dashboard. Before, only vmstorage caches were shown.

v1.91.3

Released at 2023-06-30

  • SECURITY: upgrade Go builder from Go1.20.4 to Go1.20.5. See the list of issues addressed in Go1.20.5.

  • BUGFIX: vmagent: fix possible panic at shutdown when stream aggregation is enabled. See this pull request for details.

  • BUGFIX: vmagent: fixed service name detection for consulagent service discovery in case of a difference in service name and service id. See this issue for details.

  • BUGFIX: vmalert: retry all errors except 4XX status codes while pushing via remote-write to the remote storage. Previously, errors like broken connection could prevent vmalert from retrying the request.

  • BUGFIX: vmalert: properly interrupt retry attempts on vmalert shutdown. Before, vmalert could have waited for all retries to finish for shutdown.

  • BUGFIX: vmbackupmanager: fix an issue with vmbackupmanager not being able to restore data from a backup stored in GCS. See this issue for details.

  • BUGFIX: VictoriaMetrics cluster: properly return error from /api/v1/query and /api/v1/query_range at vmselect when the -search.maxSamplesPerQuery or -search.maxSamplesPerSeries limit is exceeded. Previously incomplete response could be returned without the error if vmselect runs with -replicationFactor greater than 1. See this pull request.

  • BUGFIX: storage: prevent from possible crashloop after the migration from versions below v1.90.0 to newer versions. See this issue for details.

  • BUGFIX: vmui: fix a memory leak issue associated with chart updates. See this pull request.

  • BUGFIX: vmbackupmanager: fix removing storage data dir before restoring from backup.

  • BUGFIX: vmselect: wait for all vmstorage nodes to respond when the -replicationFactor flag is set bigger than > 1. Before, vmselect could have skip waiting for the slowest replicas to respond. This could have resulted in issues illustrated here. Now, this optimization is disabled by default and could be re-enabled by passing -search.skipSlowReplicas cmd-line flag to vmselect. See more details here.

v1.91.2

Released at 2023-06-02

  • BUGFIX: vmalert: fix nil map assignment panic in runtime introduced in this change.

  • FEATURE:vmagent: Adds follow_redirects at service discovery level of scrape configuration. See this issue. Thanks to @Haleygo for the pull request.

  • FEATURE: vmselect: Decreases startup time for vmselect with a big number of vmstorage nodes. See this issue. Thanks to @Haleygo for the pull request.

  • BUGFIX: vmalert: Properly form path to static assets in WEB UI if http.pathPrefix set. See this issue.

  • BUGFIX: vmalert: Properly set datasource query params. See this issue. Thanks to @gsakun for the pull request.

  • BUGFIX: vmalert: properly return empty slices instead of nil for /api/v1/rules for groups with present name but absent rules. See this issue.

  • BUGFIX: vmauth: Properly handle LOCAL command for proxy protocol. See this issue.

  • BUGFIX: vmbackupmanager: Fixes crash on startup. See this issue.

  • BUGFIX: vmui: fix bug with custom URL in global settings not respecting tenantID change. See this issue.

v1.91.0

  • SECURITY: upgrade Go builder from Go1.20.3 to Go1.20.4. See the list of issues addressed in Go1.20.4.

  • SECURITY: serve /robots.txt content to disallow indexing of the exposed instances by search engines. See this issue for details.

  • FEATURE: update docker compose environment to V2 in respect to V1 deprecation notice from June 2023. See Migrate to Compose V2.

  • FEATURE: deprecate -bigMergeConcurrency command-line flag, since improper configuration for this flag frequently led to uncontrolled growth of unmerged parts, which, in turn, could lead to queries slowdown and increased CPU usage. The concurrency for background merges can be controlled via -smallMergeConcurrency command-line flag, though it isn't recommended to change this flag in general case.

  • FEATURE: do not execute the incoming request if it has been canceled by the client before the execution start. See this pull request.

  • FEATURE: support time formats with timezones. For example, 2024-01-02+02:00 means January 2, 2024 at +02:00 time zone. See these docs.

  • FEATURE: expose process_* metrics at /metrics page of all the VictoriaMetrics components under Windows OS. See this pull request.

  • FEATURE: reduce the amounts of unimportant INFO logging during VictoriaMetrics startup / shutdown. This should improve visibility for potentially important logs.

  • FEATURE: upgrade base docker image (alpine) from 3.17.3 to 3.18.0. See alpine 3.18.0 release notes.

  • FEATURE: VictoriaMetrics cluster: do not pollute logs with cannot read hello: cannot read message with size 11: EOF messages at vmstorage during TCP health checks performed by Consul or other services. See this issue.

  • FEATURE: vmagent: support the ability to filter consul_sd_configs targets in more optimal way via new filter option. See this feature request.

  • FEATURE: vmagent: add support for consulagent_sd_configs. See this feature request.

  • FEATURE: vmagent: emit a warning if too small value is passed to -remoteWrite.maxDiskUsagePerURL command-line flag. See this issue.

  • FEATURE: vmalert: add support of recursive globs for -rule and -rule.templates command-line flags by using ** in the glob pattern. See this issue.

  • FEATURE: vmalert: add ability to specify custom per-group HTTP headers sent to the configured notifiers. See this issue. Thanks to @Haleygo for the pull request.

  • FEATURE: vmalert: detect alerting rules which don't match any series. See these docs and this feature request.

  • FEATURE: vmalert: support loading rules via HTTP URL. See this issue. Thanks to @Haleygo for the pull request.

  • FEATURE: vmalert: add buttons for filtering groups/rules with errors or with no-match warning in web UI for page /groups. See this issue.

  • FEATURE: vmalert: do not retry remote-write requests for responses with 4XX status codes. This aligns with Prometheus remote write specification. Thanks to @MichaHoffmann for the pull request.

  • FEATURE: vmauth: add ability to filter incoming requests by IP. See these docs and this feature request.

  • FEATURE: vmauth: add ability to proxy requests to the specified backends for unauthorized users. See this feature request.

  • FEATURE: vmauth: add ability to specify default route for unmatched requests. See this feature request.

  • FEATURE: vmauth: retry POST requests on the remaining backends if the currently selected backend isn't reachable. See this issue.

  • FEATURE: vmui: add ability to compare the data for the previous day with the data for the current day at Cardinality Explorer. See this feature request.

  • FEATURE: vmui: display histograms as heatmaps in Metrics explorer. See this feature request.

  • FEATURE: vmui: add WITH template playground. See this feature request.

  • FEATURE: vmui: add ability to debug relabeling. See this feature request.

  • FEATURE: vmui: add an ability to copy and execute queries listed at top queries page. Also make more human readable the query duration column. See this feature request and this pull request.

  • FEATURE: vmui: increase default font size for better readability.

  • FEATURE: vmui: cardinality explorer: return back a table with labels containing the highest number of unique label values. See issue.

  • FEATURE: vmui: add notification icon for queries that do not match any time series. A warning icon appears next to the query field when the executed query does not match any time series. See this feature request.

Previously filters from --vm-native-filter-match were only used to discover the metric names, and the metric names like __name__="metric_name" has been taken into account, while the remaining filters were ignored. For example --vm-native-src-addr={foo="bar",baz="abc"} may found metric_name{foo="bar",baz="abc"} and filter was treated as --vm-native-src-addr={__name__="metrics_name"}, e.g. foo="bar",baz="abc" filter was ignored. See this issue.

v1.89.1

Released at 2023-03-12

  • BUGFIX: prevent from possible cannot unmarshal timeseries from rollupResultCache panic after the upgrade to v1.89.0.

v1.89.0

  • FEATURE: add -internStringCacheExpireDuration command-line flag for controlling the lifetime of cached interned strings.

  • BUGFIX: MetricsQL: fix panic when executing the query aggr_func(rollup*(some_value)). The panic has been introduced in v1.88.0.

  • BUGFIX: vmagent: use the provided -remoteWrite.* auth options when determining whether the remote storage supports VictoriaMetrics remote write protocol. Previously the auth options were ignored. This was preventing from automatic switch to VictoriaMetrics remote write protocol.

  • BUGFIX: vmagent: do not register vm_promscrape_config_* metrics if -promscrape.config flag is not used. Previously those metrics were registered and never updated, which was confusing and could trigger false-positive alerts.

  • BUGFIX: vmctl: skip measurements with no fields when migrating data from influxdb. See this issue.

  • BUGFIX: delete failed snapshot contents from disk on failed attempt to create snapshot. Previously failed snapshot contents could remain on disk in incomplete state. See this issue

v1.88.0

Released at 2023-02-24

  • SECURITY: upgrade base docker image (alpine) from 3.17.1 to 3.17.2. See alpine 3.17.2 release notes.

  • SECURITY: upgrade Go builder from Go1.20.0 to Go1.20.1. See the list of issues addressed in Go1.20.1.

  • FEATURE: vmagent: add support for VictoriaMetrics remote write protocol. This protocol allows saving egress network bandwidth costs when sending data from vmagent to VictoriaMetrics located in another datacenter or availability zone. This also allows reducing disk IO under high load when vmagent starts queuing the collected data to disk when the remote storage is temporarily unavailable or cannot keep up with the data ingestion rate. See this feature request.

  • FEATURE: vmagent: add support for Kuma Control Plane targets discovery aka kuma_sd_configs. See this issue.

  • FEATURE: vmgateway: add the ability to verify JWT signature via JWKS endpoint. See these docs.

  • FEATURE: vmauth: automatically retry failing GET requests on all the configured backends. Previously the backend error has been immediately returned to the client without retrying the request on the remaining backends.

  • FEATURE: vmauth: choose the backend with the minimum number of concurrently executed requests among the configured backends in a round-robin manner for serving the incoming requests. This allows spreading the load among backends more evenly, while improving the response time.

  • FEATURE: vmalert enterprise: add ability to read alerting and recording rules from S3, GCS or S3-compatible object storage. See these docs.

  • FEATURE: vmctl: automatically retry requests to remote storage if up to 5 errors occur during the data migration process. This should help continuing the data migration process on temporary errors. Previously vmctl was stopping after the first error. See this feature request.

  • FEATURE: MetricsQL: support optional 2nd argument min, max or avg for rollup, rollup_delta, rollup_deriv, rollup_increase, rollup_rate and rollup_scrape_interval function. If the second argument is passed, then the function returns only the selected aggregation type. This change can be useful for situations where only one type of rollup calculation is needed. For example, rollup_rate(requests_total[1i], "max") would return only the max increase rates for requests_total metric per each interval between adjacent points on the graph. See this article for details.

  • FEATURE: MetricsQL: support optional 2nd argument open, low, high, close for rollup_candlestick function. If the second argument is passed, then the function returns only the selected aggregation type.

  • FEATURE: MetricsQL: add share(q) aggregate function.

  • FEATURE: MetricsQL: add mad_over_time(m[d]) function for calculating the median absolute deviation over raw samples on the lookbehind window d. See this feature request.

  • FEATURE: MetricsQL: add range_mad(q) function for calculating the median absolute deviation over points per each time series returned by q.

  • FEATURE: MetricsQL: add range_zscore(q) function for calculating z-score over points per each time series returned from q.

  • FEATURE: MetricsQL: add range_trim_outliers(k, q) function for dropping outliers located farther than k*range_mad(q) from the range_median(q). This should help removing outliers during query time at this issue.

  • FEATURE: MetricsQL: add range_trim_zscore(z, q) function for dropping outliers located farther than z*range_stddev(q) from range_avg(q). This should help removing outliers during query time at this issue.

  • FEATURE: vmui: show median instead of avg in graph tooltip and line legend, since median is more tolerant against spikes. See this issue.

  • FEATURE: add -search.maxSeriesPerAggrFunc command-line flag, which can be used for limiting the number of time series MetricsQL aggregate functions can return in a single query. This flag can be useful for preventing OOMs when count_values function is improperly used.

  • FEATURE: vmui: small UX improvements for mobile view. See this feature request and this pull request.

  • FEATURE: add -search.logQueryMemoryUsage command-line flag for logging queries, which need more memory than specified by this command-line flag. See this feature request. Thanks to @michal-kralik for the idea and the intial implementation.

  • FEATURE: allow setting zero value for -search.latencyOffset command-line flag. This may be needed in some cases. Previously the minimum supported value for -search.latencyOffset command-line flag was 1s.

  • BUGFIX: vmagent: immediately cancel in-flight scrape requests during configuration reload when stream parsing mode is disabled. Previously vmagent could wait for long time until all the in-flight requests are completed before reloading the configuration. This could significantly slow down configuration reload. See this issue.

  • BUGFIX: vmagent: do not wait for 2 seconds after the first unsuccessful attempt to scrape the target before performing the next attempt. This should improve scrape speed when the target closes http keep-alive connection between scrapes. See this and this issues.

  • BUGFIX: vmagent: fix Azure service discovery inside Azure Container App. See this issue. Thanks to @MattiasAng for the fix!

  • BUGFIX: do not put auxiliary directories scheduled for removal into snapshots. This should prevent from cannot create hard links from ...must-remove... errors when making snapshots / backups. See this issue.

  • BUGFIX: prevent from possible data ingestion slowdown and query performance slowdown during background merges of big parts on systems with small number of CPU cores (1 or 2 CPU cores). The issue has been introduced in v1.85.0 when implementing this feature. See also this issue.

  • BUGFIX: properly parse timestamps in milliseconds when ingesting data via OpenTSDB telnet put protocol. Previously timestamps in milliseconds were mistakenly multiplied by 1000. Thanks to @Droxenator for the pull request.

  • BUGFIX: MetricsQL: do not add extrapolated points outside the real points when using interpolate() function. See this issue.

  • SECURITY: upgrade Go builder from Go1.20.1 to Go1.20.2. See the list of issues addressed in Go1.20.2.

  • BUGFIX: vmstorage: fix a bug, which could lead to incomplete or empty results for heavy queries selecting tens of thousands of time series. See this pull request.

  • BUGFIX: vmselect: reduce memory usage and CPU usage when performing heavy queries. See this issue.

  • BUGFIX: prevent from possible invalid memory address or nil pointer dereference panic during background merge. The issue has been introduced at v1.85.0. See this issue.

  • BUGFIX: prevent from possible SIGBUS crash on ARM architectures (Raspberry Pi), which deny unaligned access to 8-byte words. Thanks to @oliverpool for narrowing down the issue and for the initial attempt to fix it.

  • BUGFIX: VictoriaMetrics cluster: always return is_partial: true in partial responses. Previously partial responses could be returned as non-partial in some cases.

  • BUGFIX: VictoriaMetrics cluster: properly take into account -rpc.disableCompression command-line flag at vmstorage. It was ignored since v1.78.0. See this pull request.

  • BUGFIX: vmagent: do not register vm_promscrape_config_* metrics if -promscrape.config flag is not used. Previously those metrics were registered and never updated, which was confusing and could trigger false-positive alerts.

  • BUGFIX: vmctl: skip measurements with no fields when migrating data from influxdb. See this issue.

  • BUGFIX: vmauth: fix cannot serve http panic when plain HTTP request is sent to vmauth configured to accept requests over proxy protocol-encoded request (e.g. when vmauth runs with -httpListenAddr.useProxyProtocol command-line flag). The issue has been introduced at v1.87.0 when implementing this feature.

  • FEATURE: vmalert: alerts state restore procedure was changed to become asynchronous. It doesn't block groups start anymore which significantly improves vmalert's startup time. This also means that -remoteRead.ignoreRestoreErrors command-line flag becomes deprecated now and will have no effect if configured. While previously state restore attempt was made for all the loaded alerting rules, now it is called only for alerts which became active after the first evaluation. See this issue.

  • FEATURE: vmui: optimize VMUI for use from smartphones and tablets. See this feature request.

  • FEATURE: vmui: add ability to search tenants in the drop-down list for the tenant selector. See this feature request.

  • FEATURE: vmui: add avg/min/max/last values to line legends and tooltips for graphs. See this feature request.

  • FEATURE: vmui: hide the default per-job resource usage dashboard if there is a custom dashboard exists at the directory specified via -vmui.customDashboardsPath command-line flag. See this feature request.

  • BUGFIX: vmagent: fix panic in HashiCorp Nomad service discovery. Thanks to @mr-karan for the pull request.

  • BUGFIX: vmalert: fix display of rules number per-group for groups with identical names in UI.

  • BUGFIX: vmalert: prevent disabling state updates tracking per rule via setting values < 1. The minimum number of update states to track is now set to 1.

  • BUGFIX: vmalert: properly update debug and update_entries_limit rule's params on config's hot-reload.

  • BUGFIX: properly initialize the vm_concurrent_insert_current metric before exposing it. Previously this metric could be left uninitialized in some cases, e.g. its value was zero. This could lead to false alerts for the query avg_over_time(vm_concurrent_insert_current[1m]) >= vm_concurrent_insert_capacity. See this issue.

  • BUGFIX: vmagent: immediately cancel in-flight scrape requests during configuration reload when using stream parsing mode. Previously vmagent could wait for long time until all the in-flight requests are completed before reloading the configuration. This could significantly slow down configuration reload. See this issue.

  • BUGFIX: vmgateway: do not validate JWT signature if no public keys are provided. Previously this could result in the error setting up jwt verification error.

v1.87.0

Released at 2023-02-01

v1.87.x is a line of LTS releases (e.g. long-time support). It contains important up-to-date bugfixes. The v1.87.x line will be supported for at least 12 months since v1.87.0 release

  • FEATURE: stream aggregation: add the ability to de-duplicate input samples before aggregation via -streamAggr.dedupInterval and -remoteWrite.streamAggr.dedupInterval command-line options.

  • FEATURE: vmui: add dark mode - it can be selected via settings menu in the top right corner. See this pull request.

  • FEATURE: vmui: improve visual appearance of the top menu. See this feature request.

  • FEATURE: vmui: embed fonts into binary instead of loading them from external sources. This allows using vmui in full from isolated networks without access to Internet. Thanks to @ScottKevill for the pull request.

  • FEATURE: vmui: add ability to switch between tenants by selecting the needed tenant in the drop-down list at the top right corner of the UI. See this pull request.

  • FEATURE: vmagent: reduce memory usage when sending stale markers for targets, which expose big number of metrics. See this and this issues.

  • FEATURE: vmagent: add __meta_kubernetes_pod_container_id meta-label to the targets discovered via kubernetes_sd_configs. This label has been added in Prometheus starting from v2.42.0. See this feature request.

  • FEATURE: vmagent: add __meta_azure_machine_size meta-label to the targets discovered via azure_sd_configs. This label has been added in Prometheus starting from v2.42.0. See this pull request.

  • FEATURE: vmauth: allow limiting the number of concurrent requests sent to vmauth via -maxConcurrentRequests command-line flag. This allows controlling memory usage of vmauth and the resource usage of backends behind vmauth. See this feature request. Thanks to @dmitryk-dk for the initial implementation.

  • FEATURE: allow using VictoriaMetrics components behind proxies, which communicate with the backend via proxy protocol. See this feature request. For example, vmauth accepts proxy protocol connections when it starts with -httpListenAddr.useProxyProtocol command-line flag.

  • FEATURE: add -internStringMaxLen command-line flag, which can be used for fine-tuning RAM vs CPU usage in certain workloads. For example, if the stored time series contain long labels, then it may be useful reducing the -internStringMaxLen in order to reduce memory usage at the cost of increased CPU usage. See this issue.

  • FEATURE: provide GOARCH=386 binaries for single-node VictoriaMetrics, vmagent, vmalert, vmauth, vmbackup and vmrestore components at releases page. See this feature request. Thanks to @denisgolius for the pull request.

  • BUGFIX: fix a bug, which could prevent background merges for the previous partitions until restart if the storage didn't have enough disk space for final deduplication and down-sampling.

  • BUGFIX: fix a bug, which could lead to increased CPU usage and disk IO usage when adding data to previous months and when the deduplication or downsampling is enabled. See this pull request.

  • BUGFIX: VictoriaMetrics cluster: propagate all the timeout-related errors from vmstorage to vmselect. Previously some timeout errors weren't returned from vmselect to vmstorage. Instead, vmstorage could log the error and close the connection to vmselect, so vmselect was logging cryptic errors such as cannot execute funcName="..." on vmstorage "...": EOF.

  • BUGFIX: vmui: add support for time zone selection for older versions of browsers. See this pull request.

  • BUGFIX: vmagent: update API version for ec2_sd_configs to fix the issue with missing __meta_ec2_availability_zone_id attribute.

  • BUGFIX: vmagent: properly return 200 OK HTTP status code when importing data via Pushgateway protocol. See this issue.

  • BUGFIX: vmagent: do not add exported_ prefix to scraped metric names, which clash with the automatically generated metric names if honor_labels: true option is set in the scrape_config. See the this and this issues.

  • BUGFIX: vmauth: allow re-entering authorization info in the web browser if the entered info was incorrect. Previously it was non-trivial to do via the web browser, since vmauth was returning 400 Bad Request instead of 401 Unauthorized http response code.

  • BUGFIX: vmauth: always log the client address and the requested URL on proxying errors. Previously some errors could miss this information.

  • BUGFIX: vmbackup: fix snapshot not being deleted after backup completion. This issue could result in unnecessary snapshots being stored, it is required to delete unnecessary snapshots manually. See the this issue.

  • BUGFIX: VictoriaMetrics cluster: fix panic on top-level vmselect nodes of multi-level setup when the -replicationFactor flag is set and request contains trace query parameter. See this issue.

v1.86.2

Released at 2023-01-18

  • SECURITY: vmbackup: do not expose basic auth passwords from -snapshot.createURL and -snapshot.deleteURL command-line flags in logs. Thanks to @toanju for the pull request.

  • FEATURE: vmui: add ability to show custom dashboards at vmui by specifying a path to a directory with dashboard config files via -vmui.customDashboardsPath command-line flag. See this feature request and these docs.

  • FEATURE: vmui: apply the step globally to all the displayed graphs. See this feature request.

  • FEATURE: vmui: improve the appearance of graph lines by using more visually distinct colors. See this feature request.

  • BUGFIX: do not slow down concurrently executed queries during assisted merges, since assisted merges already prioritize data ingestion over queries. The probability of assisted merges has been increased starting from v1.85.0 because of internal refactoring. This could result in slowed down queries when there is a plenty of free CPU resources. See this and this issues.

  • BUGFIX: reduce the increased CPU usage at vmselect to v1.85.3 level when processing heavy queries. See this issue.

  • BUGFIX: retention filters: fix FATAL: cannot locate metric name for metricID=...: EOF panic, which could occur when retention filters are enabled.

  • BUGFIX: vmagent: properly cancel in-flight service discovery requests for consul_sd_configs and nomad_sd_configs when the service list changes. See this issue.

  • BUGFIX: vmagent: dockerswarm_sd_configs: apply filters only to objects of the specified role. Previously filters were applied to all the objects, which could cause errors when different types of objects were used with filters that were not compatible with them. See this issue.

  • BUGFIX: vmagent: suppress all the scrape errors when -promscrape.suppressScrapeErrors is enabled. Previously some scrape errors were logged even if -promscrape.suppressScrapeErrors flag was set.

  • BUGFIX: vmagent: consistently put the scrape url with scrape target labels to all error logs for failed scrapes. Previously some failed scrapes were logged without this information.

  • BUGFIX: vmagent: do not send stale markers to remote storage for series exceeding the configured series limit. See this issue.

  • BUGFIX: vmagent: properly apply series limit when staleness tracking is disabled.

  • BUGFIX: vmagent: reduce memory usage spikes when big number of scrape targets disappear at once. See this issue. Thanks to @lzfhust for the initial fix.

  • BUGFIX: Pushgateway import: properly return 200 OK HTTP response code. See this issue.

  • BUGFIX: MetricsQL: properly parse M and Mi suffixes as 1e6 multipliers in 1M and 1Mi numeric constants. See this issue. The issue has been introduced in v1.86.0.

  • BUGFIX: vmui: properly display range query results at Table view. For example, up[5m] query now shows all the raw samples for the last 5 minutes for the up metric at the Table view. See this issue.

v1.86.1

Released at 2023-01-10

  • BUGFIX: return correct query results over time series with gaps. The issue has been introduced in v1.86.0.
  • BUGFIX: properly take into account the timeout passed by vmselect to vmstorage during query execution. This issue could result in the following error logs at vmstorage under load: cannot process vmselect request: cannot execute "search_v7": couldn't start executing the request in 0.000 seconds, since -search.maxConcurrentRequests=... concurrent requests are already executed. The issue has been introduced in v1.86.0.

v1.86.0

Released at 2023-01-10

It is recommended upgrading to VictoriaMetrics v1.86.1 because v1.86.0 contains a bug, which could lead to incorrect query results over time series with gaps.

Update note 1: This release changes the logic behind -maxConcurrentInserts command-line flag. Previously this flag was limiting the number of concurrent connections established from clients, which send data to VictoriaMetrics. Some of these connections could be temporarily idle. Such connections do not take significant CPU and memory resources, so there is no need in limiting their count. The new logic takes into account only those connections, which actively ingest new data to VictoriaMetrics and to vmagent. This means that the default -maxConcurrentInserts value should handle cases, which could require increasing the value in the previous releases. So it is recommended trying to remove the explicitly set -maxConcurrentInserts command-line flag after upgrading to this release and verifying whether this reduces CPU and memory usage.

Update note 2: The vm_concurrent_addrows_current and vm_concurrent_addrows_capacity metrics exported by vmstorage are replaced with vm_concurrent_insert_current and vm_concurrent_insert_capacity metrics in order to be consistent with the corresponding metrics exported by vminsert. Please update queries in dahsboards and alerting rules with new metric names if old metric names are used there.

  • FEATURE: vmagent: add support for aggregation of incoming samples by time and by labels. See these docs and this feature request.

  • FEATURE: vmagent: reduce memory usage when scraping big number of targets without the need to enable stream parsing mode.

  • FEATURE: vmagent: add support for Prometheus-compatible target discovery for HashiCorp Nomad services via nomad_sd_configs. See this feature request. Thanks to @mr-karan for the implementation.

  • FEATURE: vmagent: automatically pre-fetch metric_relabel_configs and the target labels when clicking on the debug metrics relabeling link at the http://vmagent:8429/targets page at the particular target. See these docs.

  • FEATURE: vmui: add ability to explore metrics exported by a particular job / instance. See these docs and this feature request.

  • FEATURE: allow passing partial RFC3339 date/time to time, start and end query args at querying APIs and export APIs. For example, 2022 is equivalent to 2022-01-01T00:00:00Z, while 2022-01-30T14 is equivalent to 2022-01-30T14:00:00Z. See these docs.

  • FEATURE: MetricsQL: allow using unicode letters in identifiers. For example, температура{город="Киев"} is a valid MetricsQL expression now. Previously every non-ascii letters should be escaped with \ char when used inside MetricsQL expression: \т\е\м\п\е\р\а\т\у\р\а{\г\о\р\о\д="Киев"}. Now both expressions are equivalent. Thanks to @hzwwww for the pull request.

  • FEATURE: relabeling: add support for keepequal and dropequal relabeling actions, which are supported by Prometheus starting from v2.41.0. These relabeling actions are almost identical to keep_if_equal and drop_if_equal relabeling actions supported by VictoriaMetrics since v1.38.0 - see these docs - so it is recommended sticking to keep_if_equal and drop_if_equal actions instead of switching to keepequal and dropequal.

  • FEATURE: csvimport: support empty values for imported metrics. See this issue.

  • FEATURE: vmalert: allow configuring the default number of stored rule's update states in memory via global -rule.updateEntriesLimit command-line flag or per-rule via rule's update_entries_limit configuration param. See these docs and this pull request.

  • FEATURE: improve the logic benhind -maxConcurrentInserts command-line flag. Previously this flag was limiting the number of concurrent connections from clients, which write data to VictoriaMetrics or vmagent. Some of these connections could be idle for some time. These connections do not need significant amounts of CPU and memory, so there is no sense in limiting their count. The updated logic behind -maxConcurrentInserts limits the number of active insert requests, not counting idle connections.

  • FEATURE: protect all the http endpoints with -httpAuth.* command-line flag. Previously endpoints protected by -*AuthKey command-line flags weren't protected by -httpAuth.*. This could complicate the proper security setup. See this issue.

  • FEATURE: VictoriaMetrics cluster: add -maxConcurrentInserts and -insert.maxQueueDuration command-line flags to vmstorage, so they could be tuned if needed in the same way as at vminsert nodes.

  • FEATURE: VictoriaMetrics cluster: limit the number of concurrently executed requests at vmstorage proportionally to the number of available CPU cores, since every request can saturate a single CPU core at vmstorage. Previously a single vmstorage could accept and start processing arbitrary number of concurrent requests received from big number of vmselect nodes. This could result in increased RAM, CPU and disk IO usage or event to out of memory crash at vmstorage side under high load. The limit can be fine-tuned if needed via -search.maxConcurrentRequests command-line flag at vmstorage according to these docs. vmstorage now exposes the following additional metrics at http://vmstorage:8482/metrics page:

    • vm_vmselect_concurrent_requests_capacity - the maximum number of requests allowed to execute concurrently
    • vm_vmselect_concurrent_requests_current - the current number of concurrently executed requests
    • vm_vmselect_concurrent_requests_limit_reached_total - the total number of requests, which were put in the wait queue when -search.maxConcurrentRequests concurrent requests are being executed
    • vm_vmselect_concurrent_requests_limit_timeout_total - the total number of canceled requests because they were sitting in the wait queue for more than -search.maxQueueDuration
  • BUGFIX: vmui: properly update the step value in url after the step input field has been manually changed. This allows preserving the proper step when copy-n-pasting the url to another instance of web browser. See this issue.

  • BUGFIX: vmui: properly update tooltip when quickly hovering multiple lines on the graph. See this issue.

  • BUGFIX: properly parse floating-point numbers without integer or fractional parts such as .123 and 20. during data import. See this issue.

  • BUGFIX: MetricsQL: properly parse durations with uppercase suffixes such as 10S, 5MS, 1W, etc. See this issue.

  • BUGFIX: vmagent: fix a panic during target discovery when vmagent runs with -promscrape.dropOriginalLabels command-line flag. See this issue. The bug has been introduced in v1.85.0.

  • BUGFIX: vmagent: dockerswarm_sd_configs: properly encode filters field. See this issue.

  • BUGFIX: vmagent: fix possible resource leak after hot reload of the updated consul_sd_configs. See this issue.

  • BUGFIX: vmagent: fix a panic in gce_sd_configs when the discovered instance has zero labels. See this issue. The issue has been introduced in v1.85.0.

  • BUGFIX: properly return label names starting from uppercase such as CamelCaseLabel from /api/v1/labels. See this issue.

  • BUGFIX: fix opentsdb HTTP endpoint not respecting -httpAuth.* flags. See this issue

  • BUGFIX: consistently select the sample with the biggest value out of samples with identical timestamps during querying when the deduplication is enabled according to this feature request. Previously random samples could be selected during querying.
