Aliaksandr Valialkin	d13906bf1f	lib/promscrape: exponentially increase retry interval on unsuccesful requests to scrape targets or to service discovery services ...

Aliaksandr Valialkin	e6c19cb09d	lib/promscrape/discovery/kubernetes: start watchers for pods and services before starting watchers for endpoints ... This should eliminate possible race when an update on endpoints depends on pods and/or services, which are missing in the cache yet. This could result in missing targets based on endpoints or endpointslices. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1240	2021-05-05 12:23:16 +03:00
Aliaksandr Valialkin	43c52ff77a	lib/storage: use WARNING instead of INFO level for logging dropped labels	2021-05-03 13:57:28 +03:00
Aliaksandr Valialkin	ec6becd3f5	lib/httpserver: stop the process on panics in request handlers ... Panics may leave the process in inconsistent state. That's why it is better to stop the process after the panic instead of recovering from the panic. Unfortunately, the standard net/http.Server recovers panics in request handlers. See https://github.com/golang/go/issues/16542 . That's lib/httpserver must stop the process on itself after the panic.	2021-05-03 12:00:44 +03:00

Aliaksandr Valialkin	421a92983a	lib/promscrape/discovery/kubernetes: remove a mutex at urlWatcher - use groupWatcher mutex for accessing all the urlWatcher children ... This simplifies the code a bit and reduces the probability of improper mutex handling and deadlocks.	2021-04-29 10:17:45 +03:00

Aliaksandr Valialkin	02b83e0957	lib/promscrape/discovery: remove superflouos check in registerPendingAPIWatchers ... The check `_, ok := uw.aws[aw]; !ok` isn't needed, since aw cannot exist in uw.aws because of the check inside subscribeAPIWatcher	2021-04-07 13:10:04 +03:00

Aliaksandr Valialkin	fe084fdd33	lib/promscrape/discovery/kubernetes: synchronously load Kubernetes objects on first access ... Remove async registration of apiWatchers, since it breaks discovering `role: endpoints` and `role: endpointslices` targets, which depend on pod and service objects. There is no need in reloading `endpoints` and `endpointslices` targets if the referenced `pod` or `service` objects change, since in this case the corresponding `endpoints` and `endpointslices` objects should also change because they contain ResourceVersion of the referenced `pod` or `service` objects, which is modified on object update.

Aliaksandr Valialkin	b8a5ee2e93	lib/{mergeset,storage}: allow merging smaller number of small parts ... While this may increase CPU and disk IO usage needed for background merge, this also recudes CPU usage during queries in production.

Previously targets with big number of metrics and/or labels could generated too big buffers, which then could be re-used when scraping targets with small number of metrics. This resulted in memory waste. Now big buffers are used only for targets with big number of metrics / labels, while small buffers are used for targets with small number of metrics / labels.	2020-08-16 22:30:34 +03:00

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. 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 17:29:19 +03:00

Aliaksandr Valialkin	b0131c79b6	lib/storage: improve search speed for time series matching Graphite whildcards such as foo.*.bar.baz ... Add index for reverse Graphite-like metric names with dots. Use this index during search for filters like `__name__=~"foo\\.[^.]*\\.bar\\.baz"` which end with non-empty suffix with dots, i.e. `.bar.baz` in this case. This change may "hide" historical time series during queries. The workaround is to add `[.]*` to the end of regexp label filter, i.e. "foo\\.[^.]*\\.bar\\.baz" should be substituted with "foo\\.[^.]*\\.bar\\.baz[.]*".	2020-05-27 21:48:08 +03:00
