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	69004a5f67	lib/promscrape: fix tests after the commit 658a8742ac ... The original commit copies `__address__` label to `instance` label when generating per-target labels as Prometheus does. See https://www.robustperception.io/life-of-a-label for details. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/453	2020-05-03 16:56:15 +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
