Roman Khavronenko	e2b31590e6	vmalert: add Group name as label to generated alerts and timeseries (#761) ... Solves #611	2020-09-11 23:41:12 +03:00
Roman Khavronenko	16e0bb496e	vmalert: update groups on config reload only if changes detected (#759) ... On config reload event `vmalert` reloads configuration for every group. While it works for simple configurations, the more complex and heavy installations may suffer from frequent config reloads. The change introduces the `checksum` field for every group and is set to md5 hash of yaml configuration. The checksum will change if on any change to group definition like rules order or annotation change. Comparing the `checksum` field on config reload event helps to detect if group should be updated. The groups update is now done concurrently, so reload duration will be limited by the slowest group now. Partially solves #691 by improving config reload speed.	2020-09-11 23:41:12 +03:00

Nikolay Khramchikhin	80a9dc79fe	changed vmalert behaviour (#738) ... * VMAlert start with empty rules dir There are some applications (operator for instance), that generates alerts configuration at runtime and vmalert must start correctly without rules to support this behaviour. Later application will add rules files and send SIGHUP to vmalert, which will trigger reading rules files and start rules exectuion. Removing rules files with SIGHUP signal must stop rules execution and vmalert will wait for new rules. * imports sorted * added test cases for empty rules, removed blank line * fixed imports conflict * updated tests	2020-09-03 11:07:40 +03:00

Roman Khavronenko	78afc61896	app/vmalert: extend metrics set exported by vmalert #573 (#654) ... * app/vmalert: extend metrics set exported by `vmalert` #573 New metrics were added to improve observability: + vmalert_alerts_pending{alertname, group} - number of pending alerts per group per alert; + vmalert_alerts_acitve{alertname, group} - number of active alerts per group per alert; + vmalert_alerts_error{alertname, group} - is 1 if alertname ended up with error during prev execution, is 0 if no errors happened; + vmalert_recording_rules_error{recording, group} - is 1 if recording rule ended up with error during prev execution, is 0 if no errors happened; * vmalert_iteration_total{group, file} - now contains group and file name labels. This should improve control over specific groups; * vmalert_iteration_duration_seconds{group, file} - now contains group and file name labels. This should improve control over specific groups; Some collisions for alerts and recording rules are possible, because neither group name nor alert/recording rule name are unique for compatibility reasons. Commit contains list of TODOs for Unregistering metrics since groups and rules are ephemeral and could be removed without application restart. In order to unlock Unregistering feature corresponding PR was filed - https://github.com/VictoriaMetrics/metrics/pull/13 * app/vmalert: extend metrics set exported by `vmalert` #573 The changes are following: * add an ID label to rules metrics, since `name` collisions within one group is a common case - see the k8s example alerts; * supports metrics unregistering on rule updates. Consider the case when one rule was added or removed from the group, or the whole group was added or removed. The change depends on https://github.com/VictoriaMetrics/metrics/pull/16 where race condition for Unregister method was fixed.	2020-08-09 09:42:05 +03:00

Aliaksandr Valialkin	a586b8b6d4	app/vminsert/netstorage: do not re-route every time series to more than two vmstorage nodes when certain vmstorage nodes are temporarily slower than the rest of them ... Previously vminsert may spread data for a single time series across all the available vmstorage nodes when vmstorage nodes couldn't handle the given ingestion rate. This could lead to increased usage of CPU and memory on every vmstorage node, since every vmstorage node had to register all the time series seen in the cluster. Now a time series may spread to maximum two vmstorage nodes under heavy load. Every time series is routed to a single vmstorage node under normal load.	2020-06-25 16:42:37 +03:00

nicbaz	46c5c0772c	vmselect: fix label_replace when mismatch (#579) ... As per documentation on `label_replace` function: "If the regular expression doesn't match then the timeseries is returned unchanged". Currently this behavior is not enforced, if a regexp on an existing tag doesn't match then the tag value is copied as-is in the destination tag. This fix first checks that the regular expression matches the source tag before applying anything. Given the current implementation, this fix also changes the behavior of the **MetricsQL** `label_transform` function which does not document this behavior at the moment.	2020-06-23 23:54:29 +03:00

Aliaksandr Valialkin	0fdbe5de25	app/vmselect/netstorage: increase concurrency when processing small number of time series with big number of data points per each time series ... Previously VictoriaMetrics was processing up to 32 time series in a single goroutine. This could be slow if each time series contains big number of data points (10M+ or more), since only a single CPU core could be loaded with work, while other CPU cores were idle. Fix this by launching GOMAXPROCS workers for time series processing. This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/572	2020-06-23 22:45:57 +03:00

Recover from such a situation by removing the broken metricID. New metricID will be automatically created for time series with the given metricName when new data point will arive to it.	2019-12-02 20:52:13 +02:00

Aliaksandr Valialkin	494ad0fdb3	lib/storage: remove inmemory index for recent hour, since it uses too much memory ... Production workload shows that the index requires ~4Kb of RAM per active time series. This is too much for high number of active time series, so let's delete this index. Now the queries should fall back to the index for the current day instead of the index for the recent hour. The query performance for the current day index should be good enough given the 100M rows/sec scan speed per CPU core.	2019-11-13 18:08:58 +02:00
Aliaksandr Valialkin	633dd81bb5	lib/storage: add -disableRecentHourIndex flag for disabling inmemory index for recent hour ... This may be useful for saving RAM on high number of time series aka high cardinality	2019-11-13 15:10:12 +02:00
Aliaksandr Valialkin	f1620ba7c0	lib/storage: fix inmemory inverted index issues found in v1.29 ... Issues fixed: - Slow startup times. Now the index is loaded from cache during start. - High memory usage related to superflouos index copies every 10 seconds.	2019-11-13 13:35:38 +02:00

The previous async removal process breaks in the following case during VictoriaMetrics start - VictoriaMetrics opens index, finds incomplete merge transactions and starts replaying them. - The transaction instructs removing old directories for parts, which were already merged into bigger part. - VictoriaMetrics removes these directories, but their removal is delayed due to NFS errors. - VictoriaMetrics scans partition directory after all the incomplete merge transactions are finished and finds directories, which should be removed, but weren't still removed due to NFS errors. - VictoriaMetrics panics when it finds unexpected empty directory.

Aliaksandr Valialkin	33abbec6b4	app/vmselect/promql: adjust memory limits calculations for incremental aggregate functions ... Incremental aggregate functions don't keep all the selected time series in memory - they keep only up to GOMAXPROCS time series for incremental aggregations. Take into account that the number of time series in RAM can be higher if they are split into many groups with `by (...)` or `without (...)` modifiers.

Aliaksandr Valialkin	1c777e0245	lib/storage: substitute error message about unsorted items in the index block after metricIDs merge with counter ... The origin of the error has been detected and documented in the code, so it is enough to export a counter for such errors at `vm_index_blocks_with_metric_ids_incorrect_order_total`, so it could be monitored and alerted on high error rates. Export also the counter for processed index blocks with metricIDs - `vm_index_blocks_with_metric_ids_processed_total`, so its' rate could be compared to `rate(vm_index_blocks_with_metric_ids_incorrect_order_total)`.	2019-11-06 14:32:41 +02:00

Aliaksandr Valialkin	99786c2864	app/vmselect/prometheus: add -search.maxLookback command-line flag for overriding dynamic calculations for max lookback interval ... This flag is similar to `-search.lookback-delta` if set. The max lookback interval is determined dynamically from interval between datapoints for each input time series if the flag isn't set. The interval can be overriden on per-query basis by passing `max_lookback=<duration>` query arg to `/api/v1/query` and `/api/v1/query_range`.

Aliaksandr Valialkin	bd1cf053f6	app/vmselect/promql: add increases_over_time and decreases_over_time functions ... `increases_over_time(q[d])` returns the number of `q` increases during the given duration `d`. `decreases_over_time(q[d])` returns the number of `q` decreases during the given duration `d`.	2019-09-25 20:38:51 +03:00
