Aliaksandr Valialkin	576da0fe46	app/{vminsert,vmagent}: improve documentation for -influxListenAddr command-line flag	2020-08-14 18:04:44 +03:00
Aliaksandr Valialkin	c402265e88	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 17:15:25 +03:00
Aliaksandr Valialkin	ef7e2af8f5	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 22:59:19 +03:00
Aliaksandr Valialkin	e969ef2639	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 20:57:36 +03:00
Aliaksandr Valialkin	8adba82c02	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 15:16:42 +03:00
Aliaksandr Valialkin	f3d33e23c9	app/vmstorage: improve error logging when the request times out	2020-08-10 13:23:26 +03:00
Roman Khavronenko	0be5b09fb4	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 09:41:29 +03:00

Aliaksandr Valialkin	e7959094f6	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.

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 23:50:33 +03:00

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.

Aliaksandr Valialkin	86a1cd700b	lib/storage: remove inmemory index for recent hour, since it uses too much memory ... 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. The query performance for the current day index should be good enough given the 100M rows/sec scan speed per CPU core.	2019-11-13 17:58:07 +02:00

The previous async removal process breaks in the following case during VictoriaMetrics start - VictoriaMetrics opens index, finds incomplete merge transactions and starts replaying them. - The transaction instructs removing old directories for parts, which were already merged into bigger part. - VictoriaMetrics removes these directories, but their removal is delayed due to NFS errors. - VictoriaMetrics scans partition directory after all the incomplete merge transactions are finished and finds directories, which should be removed, but weren't still removed due to NFS errors. - VictoriaMetrics panics when it finds unexpected empty directory.

Aliaksandr Valialkin	63b05c0b9f	app/vmselect/promql: adjust memory limits calculations for incremental aggregate functions ... 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

Aliaksandr Valialkin	c66a691593	app/vmselect/prometheus: add -search.maxLookback command-line flag for overriding dynamic calculations for max lookback interval ... This flag is similar to `-search.lookback-delta` if set. The max lookback interval is determined dynamically from interval between datapoints for each input time series if the flag isn't set. The interval can be overriden on per-query basis by passing `max_lookback=<duration>` query arg to `/api/v1/query` and `/api/v1/query_range`.
