Aliaksandr Valialkin	cfd6aa28e1	lib/promscrape/discovery/kubernetes: refresh endpoints and endpointslices scrape targets every 5 seconds, since they may depend on changed service and pod objects This should make endpoints and endpointslices scrape targets eventually consistent with the maximum delay of 5 seconds after the related service or pod object changes. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1240	2021-05-12 14:10:34 +03:00
Aliaksandr Valialkin	904bbffc7f	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 12:23:50 +03:00
Aliaksandr Valialkin	2ab1266593	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 10:14:26 +03:00

Aliaksandr Valialkin	b46194472f	lib/promscrape/discovery/kubernetes: reduce CPU time spent on registering big number of Kubernetes objects shared among big number of scrape jobs Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1182	2021-04-05 22:04:30 +03:00
Aliaksandr Valialkin	a51d0ec6ec	lib/promscrape/discovery/kubernetes: load objects missing in local cache from api seriver in getObjectByRole() This should fix possible race for `role: endpoints` and `role: endpointslices` service discovery, when the referred `pod` and `service` objects aren't propagated to urlWatcher cache yet. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1182#issuecomment-813353359 for details.	2021-04-05 20:31:17 +03:00
Aliaksandr Valialkin	f010d773d6	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. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1182	2021-04-05 14:20:12 +03:00
Aliaksandr Valialkin	5153410ced	lib/promscrape: support for simple HTTP proxies without `CONNECT` method support such as https://github.com/prometheus-community/PushProx See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1179	2021-04-04 00:40:40 +03:00

Aliaksandr Valialkin	d409898515	lib/promscrape/discovery/kubernetes: further optimize kubernetes service discovery for the case with many scrape jobs Do not re-calculate labels per each scrape job - reuse them instead for scrape jobs with identical Kubernetes role Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113	2021-03-14 21:14:53 +02:00

Aliaksandr Valialkin	133b288681	lib/promscrape/discovery/kubernetes: use a single watcher per apiURL Previously multiple scrape jobs could create multiple watchers for the same apiURL. Now only a single watcher is used. This should reduce load on Kubernetes API server when many scrape job configs use Kubernetes service discovery.	2021-03-11 16:43:04 +02:00
Aliaksandr Valialkin	bebcb8130c	lib/promscrape/discovery/kubernetes: localize Bookmark parsing code This is a follow-up for `e772d1c920`	2021-03-11 13:08:08 +02:00
Aliaksandr Valialkin	e772d1c920	lib/promscrape/discovery/kubernetes: reduce load on Kubernetes API server by using watch bookmarks This allows continuing object watch from the last bookbark instead of reloading all the objects on watch errors or timeouts. See https://kubernetes.io/docs/reference/using-api/api-concepts/#watch-bookmarks	2021-03-10 15:06:35 +02:00

Aliaksandr Valialkin	ab4f090c63	lib/promscrape/discovery/kubernetes: reduce memory usage further when big number of scrape jobs are configured for the same `kubernetes_sd_config` role Serialize reloading per-role objects, so they don't occupy too much memory when objects for many scrape jobs are simultaneously refreshed. Do not reload per-role objects if they were already refreshed by concurrent goroutines. This should reduce load on Kubernetes API server when big number of scrape jobs are configured for the same Kubernetes role. This is a follow-up for `17b87725ed` Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113	2021-03-07 19:51:03 +02:00
Aliaksandr Valialkin	17b87725ed	lib/promscrape/discovery/kubernetes: reduce memory usage when Kubernetes service discovery is configured on a big number of scrape jobs Previously vmagent was creating a separate Kubernetes object cache per each scrape job. This could result in increased memory usage when monitoring a Kubernetes cluster with big number of objects (pods / nodes / services, etc.) as seen at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113 Now it uses a shared map of scrape objects across multiple scrape jobs.	2021-03-05 17:29:55 +02:00
