|
|||
* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add a legend in the top right corner for shortcut keys. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2813).
|
||||
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add `toTime()` template function in the same way as Prometheus 2.38 [does](https://github.com/prometheus/prometheus/pull/10993). See [these docs](https://prometheus.io/docs/prometheus/latest/configuration/template_reference/#numbers).
|
||||
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add `$alertID` and `$groupID` template variables. These variables may be used for templating annotations or `-external.alert.source` command-line flag. See the full list of supported variables [here](https://docs.victoriametrics.com/vmalert.html#templating).
|
||||
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): add `$activeAt` template variable. See more details [here](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2999). See the full list of supported variables [here](https://docs.victoriametrics.com/vmalert.html#templating). Thanks to @laixintao.
|
||||
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): point alert source to [vmalert's UI](https://docs.victoriametrics.com/vmalert.html#web) at `/vmalert/alert?...` instead of JSON handler at `/vmalert/api/v1/alert?...`. This improves user experience. The old behavior can be achieved by setting {% raw %}`-external.alert.source=vmalert/api/v1/alert?group_id={{.GroupID}}&alert_id={{.AlertID}}`{% endraw %} command-line flag.
|
||||
|
||||
* BUGFIX: prevent from excess CPU usage when the storage enters [read-only mode](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#readonly-mode).
