Release Date: 2020-08-15 // over 3 years ago

  • 🔄 Changes since v1.39.4

    • 🔋 FEATURE: release Kubernetes operator for VictoriaMetrics - see https://github.com/VictoriaMetrics/operator .
    • 🔋 FEATURE: respect CPU limits set via cgroups. This should reduce CPU trashing and reduce memory usage for cases when VictoriaMetrics components run in containers (Docker, Kubernetes) with CPU limits. See #685 .
    • FEATURE: support %{ENV_VAR} placeholders in yaml configs in all the vm* components. Such placeholders are substituted by the corresponding environment variable values. See #583 .
    • 🔋 FEATURE: vmagent: reduce memory usage when scraping big number of targets. Thanks to @dxtrzhang for the original idea at #688 . See #689 .
    • FEATURE: reduce memory usage when exporting time series with big number of samples via /api/v1/export if max_rows_per_line is set to non-zero value. See #685 .
    • 🔋 FEATURE: add -memory.allowedBytes command-line flag for setting absolute memory limit for VictoriaMetrics caches.
    • 🔋 FEATURE: allow passing multiple args to aggregate functions such as avg(q1, q2, q3). See MetricsQL docs for details.
    • 🔋 FEATURE: update Go builder from Go1.14.7 to Go1.15.0.
    • 🛠 BUGFIX: vmagent, vminsert: prevent from busy loop on repeated timeout errors when reading streams of ingested data. See #696 .
    • 🛠 BUGFIX: vmagent, vminsert: accept precision=us and precision=µ query args according to https://docs.influxdata.com/influxdb/v1.8/tools/api/#write-http-endpoint .
    • 🛠 BUGFIX: vmagent: show real timestamp and real scrape duration on /targets page. Previously the scrape duration could be negative when calculated scrape timestamp drifts away from the real scrape timestamp.
    • 🛠 BUGFIX: vmagent: properly retry requests on the server closed connection before returning the first response byte error during service discovery API calls and target scrapes.
