Aliaksandr Valialkin	60c7397be5	all: support %{ENV_VAR} placeholders in yaml configs in all the vm* components ... Such placeholders are substituted by the corresponding environment variable values. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/583	2020-08-13 17:17:06 +03:00
Aliaksandr Valialkin	6721e47ae9	app: respect CPU limits set via cgroups ... Update GOMAXPROCS to limits set via cgroups. This should reduce CPU trashing and reduce memory usage for cases when VictoriaMetrics components run in containers with CPU limits. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/685	2020-08-11 23:01:03 +03:00
Aliaksandr Valialkin	62b6e54622	app/vmselect: reduce memory usage when exporting time series with big number of samples via /api/v1/export if max_rows_per_line is set to non-zero value ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/685	2020-08-10 20:57:43 +03:00
Aliaksandr Valialkin	c9f5c5623f	app/vmselect/netstorage: vary batch size for data unpacking depending on the available CPU cores ... This should reduce contention on the channel with unpack work for systems with high number of CPU cores	2020-08-10 15:16:48 +03:00
Aliaksandr Valialkin	b3d4ff7ee2	app/vmstorage: improve error logging when the request times out	2020-08-10 13:17:24 +03:00
Roman Khavronenko	78afc61896	app/vmalert: extend metrics set exported by vmalert #573 (#654) ... * app/vmalert: extend metrics set exported by `vmalert` #573 New metrics were added to improve observability: + vmalert_alerts_pending{alertname, group} - number of pending alerts per group per alert; + vmalert_alerts_acitve{alertname, group} - number of active alerts per group per alert; + vmalert_alerts_error{alertname, group} - is 1 if alertname ended up with error during prev execution, is 0 if no errors happened; + vmalert_recording_rules_error{recording, group} - is 1 if recording rule ended up with error during prev execution, is 0 if no errors happened; * vmalert_iteration_total{group, file} - now contains group and file name labels. 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	29bbab0ec9	lib/storage: remove prioritizing of merging small parts over merging big parts, since it doesn't work as expected ... The prioritizing could lead to big merge starvation, which could end up in too big number of parts that must be merged into big parts. Multiple big merges may be initiated after the migration from v1.39.0 or v1.39.1. It is OK - these merges should be finished soon, which should return CPU and disk IO usage to normal levels.

Aliaksandr Valialkin	d5057f6d04	app/vmagent/remotewrite: create new request on failure to send a block of data to remote storage ... Previously the request body was already consumed before the retry, so this led to the following error: http: ContentLength=... with Body length 0	2020-07-27 17:33:05 +03:00
Aliaksandr Valialkin	b191e425b3	app/vmselect/promql: improve further the accuracy of buckets_limit() function ... The accuracy is increased by mergin the smallest bucket with the smallest adjacent bucket.	2020-07-26 12:10:56 +03:00

Aliaksandr Valialkin	c91ccce50c	app/vminsert: fix relabeling for metrics ingested via Influx line protocol ...

Aliaksandr Valialkin	0bff96fe4b	lib/storage: prioritize data ingestion over heavy queries ... Heavy queries could result in the lack of CPU resources for processing the current data ingestion stream.

Expose `vm_search_delays_total` metric, which may be used in for alerting when there is no enough CPU resources for data ingestion and/or for executing heavy queries.

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

nicbaz	46c5c0772c	vmselect: fix label_replace when mismatch (#579) ... 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
nicbaz	ea2ed4b7e8	vmalert: add support for TLS configuration (#578) ... app/vmalert: add support for TLS configuration Add support for TLS optional configuration in a similar fashion to what is currently supported in other vmutils such as vmagent.

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
