Roman Khavronenko	b38edec7ee	vmalert: use stringified label keys for duplicates map in recroding rules (#1301) ... duplicates map helps to determine wheter extra labels has overriden labels which make time series unique. It was using a sorted hashed labels sequence as a key. But hashing algorithm could have collisions, so it is more convenient to not use hashing at all. Log message for recording rules duplicates was improved as well. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1293	2021-05-15 13:25:57 +03:00
Aliaksandr Valialkin	10a47af631	app/{vmalert,vmauth}: explicitly set MaxIdleConnsPerHost in net/http.Client.Transport ... By default MaxIdleConnsPerHost is set to 2.

Roman Khavronenko	5c448126dc	vmalert: add support for round_digits param in datasource package (#1278) ... Starting from v1.56.0 VM supports `round_digits` which allows to limit the number of digits after the decimal point in response value. The feature can be used to reduce entropy of produced by recording rules values and significantly improve the compression. See more details in link below. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/525	2021-05-10 11:11:45 +03:00
Roman Khavronenko	4247168a2d	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.	2021-05-10 11:06:31 +03:00

Roman Khavronenko	9cdd4696fe	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. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1252	2021-05-05 10:07:19 +03:00

Roman Khavronenko	f3a048288e	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.	2021-04-30 09:46:03 +03:00

Roman Khavronenko	87018650dd	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`.	2021-04-26 01:03:22 +03:00
Aliaksandr Valialkin	52b4b1605e	app/vmagent/remotewrite: increase the maximum possible number of inmemory blocks for systems with high amounts of RAM ...

Aliaksandr Valialkin	fb37b853e9	app/vmagent/remotewrite: count maxLabelsPerBlock as 10x of maxRowsPerBlock ...

Roman Khavronenko	c6a8ebb11f	docs: update docs ordering and formatting (#1192) ... The major change is adding `sort` directive to docs. For those docs which are copied from internal packages `sort` is added via makefile command. For the rest it is added manually since they're updated manually as well. The rest of changes is connected with markdown formatting. For example, changing headers in some files (`##` => `#`) makes navigation on .github.io to look better. This especially useful for `changelog` docs. Table of contents for `vmctl` is dropped, since we already have it autogenerated on .github.io. No link changes expected. The corresponding PR to `cluster` branch will be made in follow-up PR.	2021-04-07 13:39:16 +03:00

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

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
