Aliaksandr Valialkin	810dd74fb9	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 00:06:19 +03:00
Aliaksandr Valialkin	45385a5dc6	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.

Aliaksandr Valialkin	75c3514c5c	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 16:25:09 +03:00

Aliaksandr Valialkin	b8083b7659	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 16:19:52 +02:00

Aliaksandr Valialkin	3a444bb7bb	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.

Aliaksandr Valialkin	f422203e10	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 12:47:16 +03:00

Aliaksandr Valialkin	09f796e2ab	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).
