Haleygo	2aa0f5fc41	vmalert: add evalAlignment for rule group and fix evalutaion timstamp (#5066) ... * vmalert: add `query_time_alignment` for rule group 1. add `eval_alignment` attribute for group which by default is true. So group rule query stamp will be aligned with interval and propagated to ALERT metrics and the messages for alertmanager; 2. deprecate `datasource.queryTimeAlignment` flag. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5049	2023-10-10 12:41:19 +02:00
Haleygo	45c0e4bb31	vmalert: add eval_offset for group (#4693) ... Adds `eval_offset` attribute for Groups. If specified, Group will be evaluated at the exact time offset on the range of [0...evaluationInterval]. The setting might be useful for cron-like rules which must be evaluated at specific moments of time. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3409 Signed-off-by: Haley Wang <pipilong.25@gmail.com> Co-authored-by: hagen1778 <roman@victoriametrics.com>	2023-09-06 16:29:59 +02:00
Roman Khavronenko	91a8afa172	vmalert: reduce allocations for Prometheus resp parse (#3435) ... Method `metrics()` now pre-allocates slices for labels and results from query responses. This reduces the number of allocations on the hot path for instant requests. Signed-off-by: hagen1778 <roman@victoriametrics.com>	2022-12-05 08:34:54 +01:00
