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	069401a304	all: log error when environment variables referred from -promscrape.config are missing ... This should prevent from using incorrect config files	2022-10-18 10:47:16 +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	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	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	8550c44e31	app/vmagent: add ability to construct a label from multiple existing labels by referring them in the replacement field during relabeling ... For example: - target_label: composite-label replacement: "{{source_label1}}-{{source_label2}}"	2022-08-21 22:50:01 +03:00
Aliaksandr Valialkin	68c4ec9472	lib/promrelabel: do not split regex into multiple lines if it contains groups ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2928	2022-08-08 03:15:26 +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	3f49bdaeff	lib/promrelabel: add support for conditional relabeling via if filter ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1998	2022-02-24 02:27:26 +02:00

Aliaksandr Valialkin	207c5760ce	lib/promrelabel: fix parsing regex: true in relabeling rules	2021-09-21 23:00:53 +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
Aliaksandr Valialkin	78f83dc5ad	app/{vmagent,vminsert}: follow-up after 2fe045e2a4 ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1343	2021-06-04 20:27:58 +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	d136081040	lib/promrelabel: add more optimizations for relabeling for common cases	2021-02-22 16:33:55 +02:00
Vasily	6fcbd17bdd	Add omitempty for DisableCompression and DisableKeepAlive fields in ScrapeConfig (#796) ... * Add omitempty for DisableCompression and DisableKeepAlive fields in ScrapeConfig * Add omitempty annotation to all the default/optional values * Fix annotations after review	2020-11-13 16:19:05 +02:00
Aliaksandr Valialkin	c402265e88	all: support %{ENV_VAR} placeholders in yaml configs in all the vm* components ... Such placeholders are substituted by the corresponding environment variable values. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/583	2020-08-13 17:15:25 +03:00
Aliaksandr Valialkin	91b3482894	app/vminsert: add ability to apply relabeling to all the incoming metrics if -relabelConfig command-line arg points to a file with a list of relabel_config entries ... See https://victoriametrics.github.io/#relabeling	2020-07-02 20:39:28 +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
Aliaksandr Valialkin	5820c0ffb7	lib/promrelabel: allows regex capture groups in target_label like Prometheus does ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/569	2020-06-19 02:21:24 +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
