Hui Wang	282f13cf11	app/vmalert: improve performances when rules produce large volumes of results ... 1. Avoid storing the last evaluation results outside of rules, check for stale time series as soon as possible; 2. remove duplicated template `Clone()`. This pull request is primarily reducing memory usage when rules produce large volumes of results, as seen in https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6894. The CPU time spent on garbage collection remains high and may be addressed in a separate PR.	2024-11-14 18:21:20 +01:00
Hui Wang	9616814728	vmalert: integrate with victorialogs (#7255) ... address https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6706. See https://github.com/VictoriaMetrics/VictoriaMetrics/blob/vmalert-support-vlog-ds/docs/VictoriaLogs/vmalert.md. Related fix https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7254. Note: in this pull request, vmalert doesn't support [backfilling](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/vmalert-support-vlog-ds/docs/VictoriaLogs/vmalert.md#rules-backfilling) for rules with a customized time filter. It might be added in the future, see [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7289) for details. Feature can be tested with image `victoriametrics/vmalert:heads-vmalert-support-vlog-ds-0-g420629c-scratch`. --------- Signed-off-by: hagen1778 <roman@victoriametrics.com> Co-authored-by: hagen1778 <roman@victoriametrics.com> (cherry picked from commit 68bad22fd2)	2024-10-29 16:32:00 +01:00
