VictoriaMetrics/VictoriaMetrics v1.76.0

on GitHub

Changes

Update notes: this release introduces backwards-incompatible changes to communication protocol between vmselect and vmstorage nodes in cluster version of VictoriaMetrics, so vmselect and vmstorage nodes may log communication errors during the upgrade. These errors should stop after all the vmselect and vmstorage nodes are updated to new release.

• FEATURE: vmctl: add ability to verify files obtained via native export. See these docs and this feature request.

• FEATURE: vmui: add pre-defined dasbhoards for per-job CPU usage, memory usage and disk IO usage. See this pull request for details.

• FEATURE: vmalert: improve compatibility with Prometheus Alert Generator specification. See this pull request.

• FEATURE: vmalert: add -datasource.disableKeepAlive command-line flag, which can be used for disabling HTTP keep-alive connections to datasources. This option can be useful for distributing load among multiple datasources behind TCP proxy such as HAProxy.

• FEATURE: Cluster version of VictoriaMetrics: reduce memory usage by up to 50% for vminsert and vmstorage under high ingestion rate.

• FEATURE: vmgateway: Allow to read -ratelimit.config file from URL. Also add -ratelimit.configCheckInterval command-line option. See this issue.

• FEATURE: add the following command-line flags, which can be used for fine-grained limiting of CPU and memory usage during various API calls:

  • -search.maxFederateSeries for limiting the number of time series, which can be returned from /federate.
  • -search.maxExportSeries for limiting the number of time series, which can be returned from /api/v1/export.
  • -search.maxSeries for limiting the number of time series, which can be returned from /api/v1/series.
  • -search.maxTSDBStatusSeries for limiting the number of time series, which can be scanned during the request to /api/v1/status/tsdb.
  • -search.maxGraphiteSeries for limiting the number of time series, which can be scanned during the request to Graphite Render API.

Previously the -search.maxUniqueTimeseries command-line flag was used as a global limit for all these APIs. Now the -search.maxUniqueTimeseries is used only for limiting the number of time series, which can be scanned during requests to /api/v1/query and /api/v1/query_range.

When using cluster version of VictoriaMetrics, these command-line flags (including -search.maxUniqueTimeseries) must be passed to vmselect instead of vmstorage.

• BUGFIX: vmagent and vmauth: reduce the probability of TLS handshake error from XX.XX.XX.XX: EOF errors when -remoteWrite.url points to HTTPS url at vmauth. See this issue.
• BUGFIX: return Content-Type: text/html response header when requesting / HTTP path at VictoriaMetrics components. Previously text/plain response header was returned, which could lead to broken page formatting. See this issue.
• BUGFIX: Graphite Render API: accept floating-point values for maxDataPoints query arg, since some clients send floating-point values instead of integer values for this arg.
