Roman Khavronenko	6ad6480400	vmalert: add Group name as label to generated alerts and timeseries (#761) ... Solves #611	2020-09-11 20:52:56 +01:00
Roman Khavronenko	4cdffb04a4	vmalert: update groups on config reload only if changes detected (#759) ... On config reload event `vmalert` reloads configuration for every group. While it works for simple configurations, the more complex and heavy installations may suffer from frequent config reloads. The change introduces the `checksum` field for every group and is set to md5 hash of yaml configuration. The checksum will change if on any change to group definition like rules order or annotation change. Comparing the `checksum` field on config reload event helps to detect if group should be updated. The groups update is now done concurrently, so reload duration will be limited by the slowest group now. Partially solves #691 by improving config reload speed.	2020-09-11 20:14:30 +01:00

Nikolay Khramchikhin	764b3d4fda	changed vmalert behaviour (#738) ... * VMAlert start with empty rules dir There are some applications (operator for instance), that generates alerts configuration at runtime and vmalert must start correctly without rules to support this behaviour. Later application will add rules files and send SIGHUP to vmalert, which will trigger reading rules files and start rules exectuion. Removing rules files with SIGHUP signal must stop rules execution and vmalert will wait for new rules. * imports sorted * added test cases for empty rules, removed blank line * fixed imports conflict * updated tests	2020-09-03 11:04:42 +03:00

Roman Khavronenko	0be5b09fb4	app/vmalert: extend metrics set exported by vmalert #573 (#654) ... * app/vmalert: extend metrics set exported by `vmalert` #573 New metrics were added to improve observability: + vmalert_alerts_pending{alertname, group} - number of pending alerts per group per alert; + vmalert_alerts_acitve{alertname, group} - number of active alerts per group per alert; + vmalert_alerts_error{alertname, group} - is 1 if alertname ended up with error during prev execution, is 0 if no errors happened; + vmalert_recording_rules_error{recording, group} - is 1 if recording rule ended up with error during prev execution, is 0 if no errors happened; * vmalert_iteration_total{group, file} - now contains group and file name labels. This should improve control over specific groups; * vmalert_iteration_duration_seconds{group, file} - now contains group and file name labels. This should improve control over specific groups; Some collisions for alerts and recording rules are possible, because neither group name nor alert/recording rule name are unique for compatibility reasons. Commit contains list of TODOs for Unregistering metrics since groups and rules are ephemeral and could be removed without application restart. In order to unlock Unregistering feature corresponding PR was filed - https://github.com/VictoriaMetrics/metrics/pull/13 * app/vmalert: extend metrics set exported by `vmalert` #573 The changes are following: * add an ID label to rules metrics, since `name` collisions within one group is a common case - see the k8s example alerts; * supports metrics unregistering on rule updates. Consider the case when one rule was added or removed from the group, or the whole group was added or removed. The change depends on https://github.com/VictoriaMetrics/metrics/pull/16 where race condition for Unregister method was fixed.	2020-08-09 09:41:29 +03:00
