Aliaksandr Valialkin	123aa4c79e	lib/promscrape: properly implement ScrapeConfig.clone() ... Previously ScrapeConfig.clone() was improperly copying promauth.Secret fields - their contents was replaced with `<secret>` value. This led to inability to use passwords and secrets in `-promscrape.config` file. The bug has been introduced in v1.77.0 in the commit 67b10896d2 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2551	2022-05-07 00:05:40 +03:00
Aliaksandr Valialkin	3d0549c982	lib/promscrape: optimize getScrapeWork() function ... Reduce the number of memory allocations in this function. This improves its performance by up to 50%. This should improve service discovery speed when big number of potential targets with big number of meta-labels are generated by service discovery. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2270	2022-04-20 15:37:00 +03:00

Aliaksandr Valialkin	d6bd956930	lib/promrelabel: add keep_metrics and drop_metrics actions to relabeling rules ... These actions simlify metrics filtering. For example, - action: keep_metrics regex: 'foo|bar|baz' would leave only metrics with `foo`, `bar` and `baz` names, while the rest of metrics will be deleted. The commit also makes possible to split long regexps into multiple lines. For example, the following config is equivalent to the config above: - action: keep_metrics regex: - foo - bar - baz	2021-09-09 16:18:21 +03:00

jelmd	2fe045e2a4	new feature: debug relabeling (#1344) ... * new feature: relabel logging Use scrape_configs[x].relabel_debug = true to log metric names inkl. labels before and after relabeling. After relabeling related metrics get dropped, i.e. not submitted to servers. * vminsert wants relabel logging, too.	2021-06-04 17:50:23 +03:00

Aliaksandr Valialkin	83df20b5b5	lib/promscrape: clean references to label name and label value strings after applying per-target relabeling ... This should reduce memory usage when per-target relabeling creates big number of temporary labels with long names and/or values. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/825	2020-11-07 16:19:59 +02:00
Aliaksandr Valialkin	f42194d817	lib/promrelabel: make a copy of label with new name for action: labelmap in the same way as Prometheus does ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/812	2020-10-05 16:19:19 +03:00

Aliaksandr Valialkin	d5dddb0953	all: use %w instead of %s for wrapping errors in fmt.Errorf ... This will simplify examining the returned errors such as httpserver.ErrorWithStatusCode . See https://blog.golang.org/go1.13-errors for details.	2020-06-30 23:05:11 +03:00
Aliaksandr Valialkin	7eb171182b	lib/promrelabel: properly apply ^ and $ anchors to regex value in Prometheus relabeling rules	2020-06-25 17:19:19 +03:00
Aliaksandr Valialkin	2a39ba639d	lib/promrelabel: add support for keep_if_equal and drop_if_equal actions to relabel configs ... These actions may be useful for filtering out unneeded targets and/or metrics if they contain equal label values. For example, the following rule would leave the target only if __meta_kubernetes_annotation_prometheus_io_port equals __meta_kubernetes_pod_container_port_number: - action: keep_if_equal source_labels: [__meta_kubernetes_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]	2020-06-23 17:29:03 +03:00

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/453	2020-05-03 16:56:15 +03:00

Aliaksandr Valialkin	3b234d82e5	lib/promscrape: reload only modified scrapers on config changes ... This should improve scrape stability when big number of targets are scraped and these targets are frequently changed. Thanks to @xbsura for the idea and initial implementation attempts at the following pull requests: - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/449 - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/458 - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/459 - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/460	2020-05-03 12:45:40 +03:00

Aliaksandr Valialkin	6a75c95194	lib/promscrape: remove labels starting with __meta_ after applying relabel_configs as Prometheus does ... This should reduce CPU load during scraping when target discovery generates big number of `__meta_*` labels (for instance, k8s discovery). See https://www.robustperception.io/life-of-a-label for details.	2020-04-14 12:23:22 +03:00
Aliaksandr Valialkin	986dba5ab3	app/vmagent: do not allow non-supported fields in -remoteWrite.relabelConfig and file_sd_configs ... This should reduce possible confusion like in the https://github.com/VictoriaMetrics/VictoriaMetrics/issues/363	2020-03-06 20:19:13 +02:00
Aliaksandr Valialkin	04762344c6	app/vmagent: initial implementation for vmagent	2020-02-23 13:36:03 +02:00
