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

As per documentation on `label_replace` function: "If the regular expression doesn't match then the timeseries is returned unchanged". Currently this behavior is not enforced, if a regexp on an existing tag doesn't match then the tag value is copied as-is in the destination tag. This fix first checks that the regular expression matches the source tag before applying anything.

Production workload shows that the index requires ~4Kb of RAM per active time series. This is too much for high number of active time series, so let's delete this index. Now the queries should fall back to the index for the current day instead of the index for the recent hour.

Incremental aggregate functions don't keep all the selected time series in memory - they keep only up to GOMAXPROCS time series for incremental aggregations. Take into account that the number of time series in RAM can be higher if they are split into many groups with `by (...)` or `without (...)` modifiers.

The origin of the error has been detected and documented in the code, so it is enough to export a counter for such errors at `vm_index_blocks_with_metric_ids_incorrect_order_total`, so it could be monitored and alerted on high error rates. Export also the counter for processed index blocks with metricIDs - `vm_index_blocks_with_metric_ids_processed_total`, so its' rate could be compared to `rate(vm_index_blocks_with_metric_ids_incorrect_order_total)`.	2019-11-06 14:28:11 +02:00
