@ -34,6 +34,7 @@ The following tip changes can be tested by building VictoriaMetrics components f
* FEATURE: [Official Grafana dashboards for VictoriaMetrics](https://grafana.com/orgs/victoriametrics): add panel for tracking rate of syscalls while writing or reading from disk via `process_io_(read|write)_syscalls_total` metrics.
* FEATURE: accept timestamps in milliseconds at `start`, `end` and `time` query args in [Prometheus querying API](https://docs.victoriametrics.com/#prometheus-querying-api-usage). See [these docs](https://docs.victoriametrics.com/#timestamp-formats) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4459).
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): update retry policy for pushing data to `-remoteWrite.url`. By default, vmalert will make multiple retry attempts with exponential delay. The total time spent during retry attempts shouldn't exceed `-remoteWrite.retryMaxTime` (default is 30s). When retry time is exceeded vmalert drops the data dedicated for `-remoteWrite.url`. Before, vmalert dropped data after 5 retry attempts with 1s delay between attempts (not configurable). See `-remoteWrite.retryMinInterval` and `-remoteWrite.retryMaxTime` cmd-line flags.
* FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert.html): expose `vmalert_remotewrite_send_duration_seconds_total` counter, which can be used for determining high saturation of every connection to remote storage with an alerting query `sum(rate(vmalert_remotewrite_send_duration_seconds_total[5m])) by(job, instance) > 0.9 * max(vmalert_remotewrite_concurrency) by(job, instance)`. This query triggers when a connection is saturated by more than 90%. This usually means that `-remoteWrite.concurrency` command-line flag must be increased in order to increase the number of concurrent writings into remote endpoint. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4516).
* BUGFIX: add the following command-line flags, which can be used for limiting Graphite API calls:
`--search.maxGraphiteTagKeys` for limiting the number of tag keys returned from Graphite `/tags`, `/tags/autoComplete/*`, `/tags/findSeries` API.
