VictoriaMetrics v1.48.0 Release Notes

Release Date: 2020-11-26 // over 3 years ago
  • ๐Ÿ”„ Changes since v1.47.0

    ๐Ÿ”‹ FEATURE: added Snap package for single-node VictoriaMetrics. This simplifies installation under Ubuntu to a single command:

    snap install victoriametrics
    

    ๐Ÿ”‹ FEATURE: vmselect: add -replicationFactor command-line flag for reducing query duration when replication is enabled and a part of vmstorage nodes are temporarily slow and/or temporarily unavailable. See #711

    FEATURE: vminsert: export vm_rpc_vmstorage_is_reachable metric, which can be used for monitoring reachability of vmstorage nodes from vminsert nodes.

    FEATURE: vmagent: add Netflix Eureka service discovery (aka eureka_sd_config). See #851

    FEATURE: add filters option to dockerswarm_sd_config like Prometheus did in v2.23.0 - see prometheus/prometheus#8074

    FEATURE: expose __meta_ec2_ipv6_addresses label for ec2_sd_config like Prometheus will do in the next release.

    ๐Ÿ”‹ FEATURE: add -loggerWarnsPerSecondLimit command-line flag for rate limiting of WARN messages in logs. See #905

    ๐Ÿ”‹ FEATURE: apply loggerErrorsPerSecondLimit and -loggerWarnsPerSecondLimit rate limit per caller. I.e. log messages are suppressed if the same caller logs the same message at the rate exceeding the given limit. See #905 (comment)

    ๐Ÿ”‹ FEATURE: add remoteAddr to slow query log in order to simplify identifying the client that sends slow queries to VictoriaMetrics. Slow query logging is controlled with -search.logSlowQueryDuration command-line flag.

    ๐Ÿ”‹ FEATURE: add /tags/delSeries handler from Graphite Tags API. See https://victoriametrics.github.io/#graphite-tags-api-usage

    ๐Ÿ”‹ FEATURE: log metric name plus all its labels when the metric timestamp is out of the configured retention. This should simplify detecting the source of metrics with unexpected timestamps.

    ๐Ÿ”‹ FEATURE: add -dryRun command-line flag to single-node VictoriaMetrics in order to check config file pointed by -promscrape.config.

    ๐Ÿ›  BUGFIX: properly parse Prometheus metrics with exemplars such as foo 123 # {bar="baz"} 1.

    ๐Ÿ›  BUGFIX: properly parse "infinity" values in OpenMetrics format. See #924
