f551b99082 docs/CHANGELOG.md: document vmalert fix for state restoration on startup 2021-05-10 11:10:34 +03:00

35237fe1f5 vmalert: fix error when rule didn't start if restore failed (#1279) 
Previously, `startGroup` could exit on restore errors despite the
`remoteRead.ignoreRestoreErrors` flag value. Now vmalert checks the
flag value before deciding whether to return error or just log it.

bb7e113dd4 vmalert: add flag to control behaviour on startup for state restore errors (#1265) 
Alerting rules now can return specific error type ErrStateRestore to indicate
whether restore state procedure failed. Such errors were returned and logged
before as well. But now user can specify whether to just log these errors
(remoteRead.ignoreRestoreErrors=true) or to stop the process
(remoteRead.ignoreRestoreErrors=false). The latter is important when VM isn't
ready yet to serve queries from vmalert and it needs to wait.

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.

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.

b55677e93d Vmalert: adjust time param for datasource queries according to evaluationInterval (#1257) 
* Simplify arguments list for fn `queryDataSource` to improve readbility

* vmalert: adjust `time` param according to rule evaluation interval

With this change, vmalert will start to use rule's evaluation interval
for truncating the `time` param. This is mostly needed to produce consistent
time series with timestamps unaffected by vmalert start time. Now, timestamp
becomes predictable.
Additionally, adjustment is similar to what Grafana does for plotting range graphs.
Hence, recording rule series and recording rule expression plotted in grafana
suppose to become similar in most of cases.

0ceb4f7565 vmalert: keep the returned timestamp when persisting recording rule (#1245) 
Previously, vmalert used `lastExecTime` timestamp when writing recording rules
to the remote storage. This may be incorrect, if vmalert uses `datasource.lookback` flag,
which means rule's expression will be executed at some moment in the past.
To avoid such situations, vmalert now will use returned timestamp instead of `lastExecTime`.
