Aliaksandr Valialkin	1a28f0e5b3	lib/promrelabel: pass query args via query string at /metric-relabel-debug and /target-relabel-debug pages if their length doesnt exceed 1000 ... This allows copy-n-pasting the url to another browser window and seeing the same result. The limit in 1000 chars is selected in order to prevent from potential issues with systems which limit the url length such as Internet Explorer - see https://stackoverflow.com/questions/812925/what-is-the-maximum-possible-length-of-a-query-string If the limit is exceeded, then query args are sent via POST method and aren't visible in the url.

Aliaksandr Valialkin	0dea3b71da	lib/promscrape: pre-fetch metric_relabel_configs rules when debugging metric relabeling for a particular target ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3407	2023-01-05 03:26:49 -08:00

Aliaksandr Valialkin	31886aef3d	lib/promrelabel: add support for keepequal and dropequal relabeling actions ... These actions are supported by Prometheus starting from v2.41.0 See https://github.com/prometheus/prometheus/pull/11564 , https://github.com/prometheus/prometheus/issues/11556 and https://github.com/prometheus/prometheus/issues/3756 Side note: It's a pity that Prometheus developers decided inventing `keepequal` and `dropequal` relabeling actions instead of adding support for `keep_if_equal` and `drop_if_equal` relabeling actions supported by VictoriaMetrics since June 2020 - see 2a39ba639d .	2022-12-21 20:04:55 -08:00
Aliaksandr Valialkin	a8b8e23d68	lib/promscrape: implement target-level and metric-level relabel debugging ... Target-level debugging is performed by clicking the 'debug' link at the corresponding target on either http://vmagent:8429/targets page or on http://vmagent:8428/service-discovery page. Metric-level debugging is perfromed at http://vmagent:8429/metric-relabel-debug page. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3407 See https://docs.victoriametrics.com/vmagent.html#relabel-debug	2022-12-10 02:09:44 -08:00

Aliaksandr Valialkin	f325410c26	lib/promscrape: optimize service discovery speed ... - Return meta-labels for the discovered targets via promutils.Labels instead of map[string]string. This improves the speed of generating meta-labels for discovered targets by up to 5x. - Remove memory allocations in hot paths during ScrapeWork generation. The ScrapeWork contains scrape settings for a single discovered target. This improves the service discovery speed by up to 2x.	2022-11-29 21:26:00 -08:00
Aliaksandr Valialkin	869e0f9f85	lib/promrelabel: go fmt after 5cec9706dc	2022-10-29 05:17:10 +03:00
Aliaksandr Valialkin	5cec9706dc	lib/promrelabel: add a test from https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3251 ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3251	2022-10-29 04:33:38 +03:00
Aliaksandr Valialkin	518c340ae3	lib/envtemplate: allow referring env vars from other env vars via %{ENV_VAR} syntax ... This is a follow-up for 02096e06d0	2022-10-26 14:49:33 +03:00

Aliaksandr Valialkin	b6e8c1403a	lib/promrelabel: add relabeling tests when the source label is missing	2022-10-17 14:47:52 +03:00
Aliaksandr Valialkin	50f5eae0e0	lib/promrelabel: remove unconditional sorting of the labels in ParsedConfigs.Apply(), since the sorting isnt needed in many places ... Sort labels explicitly after calling the ParsedConfigs.Apply() when needed. This reduces CPU usage when performing metric-level relabeling, where labels' sorting isn't needed.	2022-10-09 14:51:16 +03:00
Aliaksandr Valialkin	f9df0cae16	lib/promscrape: allow specifying full target url in __address__ label ... Previously the `__address__` label could contain only `host:port` part of the target url, while the scheme and metrics path were obtained from `__scheme__` and `__metrics_path__` labels. Now it is possible to set the full url in `__address__` label. This makes valid the following scrape config, which is frequently used by novice users: scrape_configs: - job_name: foo static_configs: - targets: - http://host1/metrics1 - https://host2/metrics2	2022-10-07 22:43:04 +03:00

Aliaksandr Valialkin	a18d6d5ccc	lib/promrelabel: optimize action: replace for non-trivial regex values ... Cache `action: replace` results for non-trivial regexs and return them next time instead of performing CPU-intensive regex replacement. Optimize also `action: labelmap_all` and `action: replace_all` in the same way.	2022-09-30 12:25:05 +03:00
Aliaksandr Valialkin	146021a076	lib/promrelabel: there is no need in calling regex.HasPrefix() after the optimization at 17289ff481	2022-09-30 10:49:18 +03:00

Aliaksandr Valialkin	ef435f8cc4	lib/promrelabel: add SanitizeName() function for sanitizing Prometheus metric names and label names ... Optimize this function by using results cache for input strings. Use this function all over the code. This is a follow-up for fcffdba9dc Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3113	2022-09-28 10:40:59 +03:00
Aliaksandr Valialkin	a2cd79576f	lib/promrelabel: call PromRegex.MatchString() on a slow path only if it contains non-empty literal prefix ... This should improve slow path speed for regexps without literal prefixes	2022-08-26 21:48:30 +03:00
Aliaksandr Valialkin	f49c9bb700	lib/promrelabel: optimize common regex mismatch cases for action: replace and action: labelmap	2022-08-26 15:45:31 +03:00
Aliaksandr Valialkin	4c6916f32a	lib/promrelabel: use regexutil.PromRegex for regex matching in actions labeldrop,labelkeep,drop and keep ... This makes possible optimizing additional cases inside regexutil.PromRegex	2022-08-26 15:23:45 +03:00
Aliaksandr Valialkin	7afe8450fc	lib/promrelabel: optimize matching for commonly used regex patterns in if option ... The following regex patterns are optimized: - literal string match, e.g. "foo" - prefix match, e.g. "foo.*" and "foo.+" - substring match, e.g. ".*foo.*" and ".+foo.+" - alternate values match, e.g. "foo|bar|baz"	2022-08-26 14:53:06 +03:00
Aliaksandr Valialkin	0ad3bbadd3	lib/regexutil: add Simplify() function for simplifying the regular expression	2022-08-26 11:57:12 +03:00
Aliaksandr Valialkin	b373661988	lib/promrelabel: optimize action: {drop,keep,labeldrop,labelkeep} with anchored regex prefix ... The following commonly used relabeling rules must work faster now: - action: labeldrop regex: "^foo.+$" - action: labeldrop regex: "^bar.*"	2022-08-25 23:23:55 +03:00
Aliaksandr Valialkin	0d4ea03a73	lib/promrelabel: optimize action: {labeldrop,labelkeep,keep,drop} with regex containing alternate values ... For example, the following relabeling rule must work much faster now: - action: labeldrop regex: "foo|bar|baz"	2022-08-24 17:54:29 +03:00

Aliaksandr Valialkin	e6ed92529b	all: remove explicit "xxhash" name when importing github.com/cespare/xxhash/v2 package ... This package already has the same name, so there is no need in explicit name	2022-06-21 20:23:32 +03:00

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.

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
