This reverts commit ac45082216. Reason for revert: the previous behavior for VictoriaMetrics is easier to understand and use by users - functions, which don't change the meaning of the time series shouldn't drop metric name.

Now `/targets` endpoint accepts optional `show_original_labels=1` query arg, which shows original labels for each target. This may simplify debugging for target relabeling. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/651	2020-10-08 18:59:25 +03:00
Aliaksandr Valialkin	f9f8e4a39c	app/vmalert: do not pring description for all the flags on config errors ... The description is too big to consume by human and it just distracts humans.	2020-10-08 13:35:46 +03:00

Aliaksandr Valialkin	fd7dd5064a	lib/storage: code cleanup after 10f2eedee0 ... Remove the code that uses metricIDs caches for the current and the previous hour during metricIDs search, since this code became unused after implementing per-day inverted index almost a year ago. While at it, fix a bug, which could prevent from finding time series with names containing dots (aka Graphite-like names such as `foo.bar.baz`).	2020-10-01 19:12:04 +03:00

Aliaksandr Valialkin	ffa6581c46	app/vminsert: refresh the list of healthy storage nodes only if the the row cannot be sent to destination storage node ...

Roman Khavronenko	16e0bb496e	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 23:41:12 +03:00
Aliaksandr Valialkin	b776a93608	app/vmselect/promql: support composite durations like Prometheus 2.21 does ...

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 09:42:05 +03:00

Aliaksandr Valialkin	a586b8b6d4	app/vminsert/netstorage: do not re-route every time series to more than two vmstorage nodes when certain vmstorage nodes are temporarily slower than the rest of them ... Previously vminsert may spread data for a single time series across all the available vmstorage nodes when vmstorage nodes couldn't handle the given ingestion rate. This could lead to increased usage of CPU and memory on every vmstorage node, since every vmstorage node had to register all the time series seen in the cluster. Now a time series may spread to maximum two vmstorage nodes under heavy load. Every time series is routed to a single vmstorage node under normal load.	2020-06-25 16:42:37 +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. Given the current implementation, this fix also changes the behavior of the **MetricsQL** `label_transform` function which does not document this behavior at the moment.	2020-06-23 23:54:29 +03:00

Aliaksandr Valialkin	0fdbe5de25	app/vmselect/netstorage: increase concurrency when processing small number of time series with big number of data points per each time series ... Previously VictoriaMetrics was processing up to 32 time series in a single goroutine. This could be slow if each time series contains big number of data points (10M+ or more), since only a single CPU core could be loaded with work, while other CPU cores were idle. Fix this by launching GOMAXPROCS workers for time series processing. This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/572	2020-06-23 22:45:57 +03:00

Before the change we were sending notifications to notifier if following conditions are met: * alert is in Fire state * alert is in Inactive state We were sending Inactive notifications to resolve alert ASAP.
