VictoriaMetrics v1.39.3 Release Notes

Release Date: 2020-08-05 // over 3 years ago

  • 🔄 Changes since v1.39.2

    • FEATURE: add MetricsQL functions for calculating z-score over time range and over a group of time series. The following functions are added: zscore_over_time(m[d]) and zscore(q) by (group). They may be used for anomaly detection and alerting. See more details at MetricsQL docs.
    • 🔋 FEATURE: show X-Forwarded-For contents on /api/v1/status/active_queries page. See #659 .
    • 🔋 FEATURE: vmbackup, vmrestore: allow using ~/.aws/config without region. Determining bucket region via us-west-2. See vmbackup docs for details.
    • 🔋 FEATURE: use warning level instead of info level for logging slow queries that take longer than -search.logSlowQueryDuration.
    • 🛠 BUGFIX: vmagent: prevent from closing keep-alive connections to remote storage in case -remoteWrite.queues is set to value bigger than 1. See #663 .
    • 🛠 BUGFIX: reduce the maximum number of concurrent merge workers to GOMAXPROCS/2. The limit has been raised to GOMAXPROCS in v1.39.2, but it has been appeared that this may increase query latency, because more CPU cores are busy with merges.
    • 🛠 BUGFIX: do not adjust start and end query args passed to /api/v1/query_range when -search.disableCache command-line flag is set. See #563 .
