Aliaksandr Valialkin	fd596945e7	lib/promscrape: improve logging for scrape_config_files parse errors ... Log the actual file path, which led to the parse error. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1789	2021-11-08 13:34:12 +02:00
Aliaksandr Valialkin	cbfc7b7c92	app/{vminsert,vmagent}: hide passwords and auth tokens by default at /config page ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1764	2021-11-05 14:41:16 +02:00
Aliaksandr Valialkin	aa534c2582	lib/promscrape: add -promscrape.maxResponseHeadersSize command-line flag for tuning the maximum http response headers size from Prometheus scrape targets	2021-11-03 22:26:56 +02:00
Aliaksandr Valialkin	74b8af9891	lib/promscrape: add collapse and expand buttons per each group of targets from the same scrape job	2021-10-27 20:03:24 +03:00
Aliaksandr Valialkin	6608705652	app/{vmalert,vmagent}: improve the distribution of scrape offsets among targets / rules ... Previously only the lower part of 64-bit hash was used for calculating the offset. This may give uneven distribution in some cases. So let's use all the available 64 bits from the hash for calculating the offset.	2021-10-27 19:59:16 +03:00
Aliaksandr Valialkin	4821adfd95	lib/promscrape: properly show proxy_url option value at /config page ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1755	2021-10-26 21:23:54 +03:00
Aliaksandr Valialkin	7fa15f7f86	lib/promscrape: do not populate response body to memory in stream parsing mode if -promscrape.noStaleMarkers is set ... The response body isn't used if -promscrape.noStaleMarkers is set after the commit 2876137c92 , so there is no sense in pupulating it in memory. This should reduce memory usage when scraping big responses. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1728#issuecomment-949630694	2021-10-22 16:44:44 +03:00
Aliaksandr Valialkin	6106d4069d	lib/promscrape: do not sort original labels and do not intern label string for the original labels before the sharding code is executed ... This should reduce CPU and memory usage in shard mode when service discovery finds big number of scrape targets with many long labels. See https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets This is a follow-up after 9882cda8b9 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1728	2021-10-22 13:54:30 +03:00
Aliaksandr Valialkin	2876137c92	lib/promscrape: reduce memory usage if -promscrape.noStaleMarkers command-line flag is passed ... Do not store in memory the response from the last scrape per each target if -promscrape.noStaleMarkers option is enabled. This should reduce memory usage when the scraped targets return large responses.	2021-10-22 13:10:29 +03:00
Aliaksandr Valialkin	3408a05d12	lib/promscrape/discovery/kubernetes: log a warning if role: endpoints discovers more than 1000 targets per a single endpoint ... In this case `role: endpointslice` must be used instead. See the following references: * https://kubernetes.io/docs/reference/labels-annotations-taints/#endpoints-kubernetes-io-over-capacity * https://github.com/kubernetes/kubernetes/pull/99975 * https://github.com/prometheus/prometheus/issues/7572#issuecomment-934779398	2021-10-19 13:20:40 +03:00
Nikolay	cbcc622786	changes job source for /target api (#1723) ... use jobNameOriginal instead of relabeled as prometheus does https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1707	2021-10-19 08:49:36 +03:00
Aliaksandr Valialkin	c37f285466	lib/promscrape: set honor_timestamps: true by default if this option isnt set explicitly in scrape configs ... This aligns the behavior to Prometheus - see https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config	2021-10-16 20:49:08 +03:00
Aliaksandr Valialkin	c055bc478c	lib/promscrape: expose promscrape_series_limit_max_series and promscrape_series_limit_current_series metrics per each scrape target with the enabled unique series limiter	2021-10-16 18:47:13 +03:00
Aliaksandr Valialkin	06b0982d6b	lib/promscrape: always initialize http client for stream parsing mode ... Stream parsing mode can be automatically enabled when scraping targets with big response bodies exceeding the -promscrape.minResponseSizeForStreamParse , so it must be always initialized.	2021-10-16 13:18:23 +03:00
Aliaksandr Valialkin	32793adbd9	lib/promscrape: store the last scraped response in compressed form if its size exceeds -promscrape.minResponseSizeForStreamParse ... This should reduce memory usage when scraping targets with big response bodies.	2021-10-16 13:00:30 +03:00
Aliaksandr Valialkin	9866dd95c1	lib/promscrape: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice ... This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode at the cost of the increased memory usage, since now the potentially big response is kept in the lastScrape byte slice per each scrapeWork. In practice the memory usage increase shouldn't be big, since the response size is usually much smaller than the parsed metrics from this response after the relabeling, which usually adds a big pile of target-specific labels per each metric.	2021-10-15 15:39:23 +03:00
Aliaksandr Valialkin	f6d33596ff	lib/promscrape/discovery/kubernetes: rename endpointslices.go -> endpointslice.go in order to be consistent with EndpointSlice struct name ... This is a follow-up for 31b42b30b6	2021-10-15 12:27:12 +03:00
Aliaksandr Valialkin	bbd34fa15e	lib/promscrape: add -promscrape.minResponseSizeForStreamParse command-line option for automatic switching to stream parsing mode when scraping targets with big responses ... This should reduce memory usage when vmagent scrapes targets with non-uniform response sizes. This is common case in Kubernetes monitoring.	2021-10-14 12:29:35 +03:00
Aliaksandr Valialkin	1a7287c408	lib/promscrape: return error if sample_limit or series_limit options are set when stream parsing mode is enabled	2021-10-14 12:11:23 +03:00
Aliaksandr Valialkin	e3c8304deb	lib/promscrape: add ability to show the original labels for discovered targets at /targets page ... See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1698	2021-10-13 15:59:58 +03:00

Aliaksandr Valialkin	48e3e6c8df	lib/promscrape: add ability to configure scrape_timeout and scrape_interval via relabeling ... See https://github.com/prometheus/prometheus/pull/8911	2021-09-12 13:33:41 +03:00
Aliaksandr Valialkin	f3e89754a9	lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added metric ... Also reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics. The main idea is to perform the calculations on scrape_series_added and series_limit only if the set of metrics exposed by the target has been changed. Scrape targets rarely change the set of exposed metrics, so this optimization should reduce CPU usage in general case.	2021-09-12 12:53:14 +03:00
Aliaksandr Valialkin	9286107e82	lib/promscrape: send stale markers for disappeared metrics like Prometheus does	2021-09-11 10:51:04 +03:00
Aliaksandr Valialkin	4aeb8db83f	lib/promscrape: add ability to set series_limit and stream_parse options via relabeling ... This allows managing these options on a per-target basis. Typical use case: to manage these options for pods via Kubernetes annotations.	2021-09-09 18:49:39 +03:00
Aliaksandr Valialkin	468f941f7e	lib/promscrape: add the actual job name to the labels of promscrape_series_limit_rows_dropped_total metric	2021-09-09 17:37:37 +03:00
Aliaksandr Valialkin	086b5d0cf1	lib/promscrape: add scrape_ prefix to job and target labels exported by promscrape_series_limit_rows_dropped_total metric ... This is needed in order to prevent from possible clash with the corresponding (job, target) labels for the job, which scrapes this metric.	2021-09-09 17:29:21 +03:00
Aliaksandr Valialkin	f77dde837a	lib/promscrape: add the ability to limit the number of unique series per each scrape target ... The number of series per target can be limited with the following options: * Global limit with `-promscrape.maxSeriesPerTarget` command-line option. * Per-target limit with `max_series: N` option in `scrape_config` section.

Aliaksandr Valialkin	5c63d69454	lib/promscrape/discovery/kubernetes: return back support role: endpointslices, since it is used by VictoriaMetrics operator ... This is a follow up commit after 31b42b30b6	2021-08-29 12:37:03 +03:00
Aliaksandr Valialkin	31b42b30b6	lib/promscrape/discovery/kubernetes: rename role: endpointslices to role: endpointslice to be consistent with Prometheus ... See 2ec6c7dbb8/discovery/kubernetes/kubernetes.go (L99)	2021-08-29 11:23:08 +03:00
Aliaksandr Valialkin	2e001db4de	lib/promscrape/discovery/kubernetes: use v1 API instead of v1beta1 API for role: ingress and role: endpointslices ... This should fix service discovery for these roles in Kubernetes v1.22 and newer versions. See https://kubernetes.io/docs/reference/using-api/deprecation-guide/#ingress-v122 The corresponding change in Prometheus - https://github.com/prometheus/prometheus/pull/9205	2021-08-29 11:16:59 +03:00
Aliaksandr Valialkin	10f960fa0c	lib/promscrape: add ability to load scrape configs from multiple files ... See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1559	2021-08-26 08:51:16 +03:00
Aliaksandr Valialkin	c27ee35c5c	lib/promscrape: expose promscrape_discovery_http_errors_total metric for tracking errors per each http_sd config	2021-08-25 13:05:49 +03:00
Aliaksandr Valialkin	d5622b32e2	lib/promscrape: reduce memory and CPU usage when Prometheus staleness tracking is enabled for metrics from deleted / disappeared scrape targets ... Store the scraped response body instead of storing the parsed and relabeld metrics. This should reduce memory usage, since the response body takes less memory than the parsed and relabeled metrics. This is especially true for Kubernetes service discovery, which adds many long labels for all the scraped metrics. This should also reduce CPU usage, since the marshaling of the parsed and relabeld metrics has been substituted by response body copying.

Aliaksandr Valialkin	f46a73dcdd	lib/promscrape: use scrapeTimestamp when storing stale markers for failed scrape ... This will make timestamps for stale markers more consistent for timestamps for other samples	2021-08-19 14:18:05 +03:00
Aliaksandr Valialkin	c09446a9aa	lib/promscrape: send stale markers for the previously scraped metrics on failed scrapes like Prometheus does	2021-08-18 21:59:03 +03:00
Aliaksandr Valialkin	cdc372bb98	app/vmselect: add -search.noStaleMarkers command-line flag for disabling stale markers handling in queries ... This option allows reducing CPU usage a bit when VictoriaMetrics is used for collecting and processing non-Prometheus data. For example, InfluxDB line protocol, Graphite, OpenTSDB, CSV, etc.	2021-08-18 13:59:02 +03:00
Aliaksandr Valialkin	226143f31b	lib/promscrape: add ability to disable sending Prometheus staleness markers with -promscrape.disableStaleMarkers command-line flag ... This option can be useful when vmagent consumes too much additional memory for staleness markers functionality and when staleness markers aren't needed.	2021-08-18 13:43:21 +03:00
