Roman Khavronenko	3adf8c5a6f	vmalert: explicitly set extra labels to alert entities (#886) ... The previous implementation treated extra labels (global and rule labels) as separate label set to returned time series labels. Hence, time series always contained only original labels and alert ID was generated from sorted labels key-values. Extra labels didn't affect the generated ID and were applied on the following actions: - templating for Summary and Annotations; - persisting state via remote write; - restoring state via remote read. Such behaviour caused difficulties on restore procedure because extra labels had to be dropped before checking the alert ID, but that not always worked. Consider the case when expression returns the following time series `up{job="foo"}` and rule has extra label `job=bar`. This would mean that restored alert ID will be always different to the real time series because of collision. To solve the situation extra labels are now always applied beforehand and `vmalert` doesn't store original labels anymore. However, this could result into a new error situation. Consider the case when expression returns two time series `up{job="foo"}` and `up{job="baz"}`, while rule has extra label `job=bar`. In such case, applying extra labels will result into two identical time series and `vmalert` will return error: `result contains metrics with the same labelset after applying rule labels` https://github.com/VictoriaMetrics/VictoriaMetrics/issues/870	2020-11-10 00:27:32 +02:00

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

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
