Jeremy PLANCKEEL	16fdd2af8a	test(golang): add test to function addRowToTimeseries (#3282 ) Co-authored-by: jplanckeel-externe <jplanckeel.externe@bedrockstreaming.com>	2022-11-09 15:41:26 +02:00
Aliaksandr Valialkin	7fa5d043f5	lib/promscrape/discovery/consul: add `__meta_consul_partition` label in the same way as Prometheus does See https://github.com/prometheus/prometheus/pull/11482	2022-11-07 15:25:53 +02:00
Aliaksandr Valialkin	76e8888272	lib/promscrape: properly add `exported_` prefix to labels, which clash with target labels if `honor_labels: true` option isn't set. The issue was in the `labels := dst[offset:]` line in the beginning of appendExtraLabels() function. The `dst` may be re-allocated when adding extra labels to it. In this case the addition of `exported_` prefix to labels inside `labels` slice become invisible in the returned `dst` labels. While at it, properly handle some corner cases: - Add additional `exported_` prefix to clashing metric labels with already existing `exported_` prefix. - Store scraped metric names in `exported___name__` label if scrape target contains `__name__` label. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3278 Thanks to @jplanckeel for the initial attempt to fix this issue at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3281	2022-10-28 22:14:26 +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.

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	4998402004	lib/promscrape: add `external_labels` from `global` section of `-promscrape.config` after the relabeling is applied to the scraped metrics This aligns with Prometheus behaviour.

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	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	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
