VictoriaMetrics/VictoriaMetrics v1.66.0 on GitHub

Changes

FEATURE: vmalert: add web UI with the list of alerting groups, alerts and alert statuses. See this pull request.
FEATURE: vmalert: add -rule.maxResolveDuration command-line flag, which could be used for limiting the auto-resolve duration for the alerting rule. By default it is limited to 3x evaluation interval. This could be too high for big evaluation intervals. See this issue.
FEATURE: vmalert: add support for Bearer token authorization for -datasource.url, -remoteRead.url and -remoteWrite.url. See this issue.
FEATURE: vmagent: send stale markers for disappeared metrics like Prometheus does. Previously stale markers were sent only when the scrape target disappears or when it becomes temporarily unavailable. See these docs for details.
FEATURE: vmagent: add ability to set series_limit option for a particular scrape target via __series_limit__ label. This allows setting the limit on the number of time series on a per-target basis. See these docs for details.
FEATURE: vmagent: add ability to set stream_parse option for a particular scrape target via __stream_parse__ label. This allows managing the stream parsing mode on a per-target basis. See these docs for details.
FEATURE: vmagent: add ability to set scrape_interval and scrape_timeout options for a particular target via __scrape_interval__ and __scrape_timeout__ labels in the same way as Prometheus 2.30 does. See this pull request.
FEATURE: vmagent: generate scrape_timeout_seconds metric per each scrape target, so the target saturation could be calculated with scrape_duration_seconds / scrape_timeout_seconds. See the corresponding pull request from Prometheus 2.30.
FEATURE: vmagent: reduce CPU usage when calculating the number of newly added series per scrape (this number is sent to remote storage in scrape_series_added metric).
FEATURE: vmagent: reduce CPU usage when applying series_limit to scrape targets with constant set of metrics. See more information about series_limit here.
FEATURE: vminsert: disable rerouting by default when a few of vmstorage nodes start accepting data at lower speed than the rest of vmstorage nodes. This should improve VictoriaMetrics cluster stability during rolling restarts and during spikes in time series churn rate. The rerouting can be enabled by passing -disableRerouting=false command-line flag to vminsert.
FEATURE: vmauth: do not put invalid auth tokens into log by default due to security reasons. The logging can be returned back by passing -logInvalidAuthTokens command-line flag to vmauth. Requests with invalid auth tokens are counted at vmagent_http_request_errors_total{reason="invalid_auth_token"} metric exposed by vmauth at /metrics page.
FEATURE: add new relabeling actions: keep_metrics and drop_metrics. This simplifies metrics filtering by metric names. See these docs for more details.
FEATURE: allow splitting long regex in relabeling filters into an array of shorter regexps, which can be put into multiple lines for better readability and maintainability. See these docs for more details.
FEATURE: optimize performance for queries with regexp filters on metric name like {__name__=~"metric1|...|metricN"}. See this pull request from @faceair.
FEATURE: vmui: use Prometheus-compatible query args, so vmui could be accessed from graph editor in Grafana. See this pull request. Thanks to @Loori-R.
FEATURE: vmselect: automatically add missing port to -storageNode hostnames. For example, -storageNode=vmstorage1,vmstorage2 is automatically translated to -storageNode=vmstorage1:8401,vmstorage2:8401. This simplifies manual setup of VictoriaMetrics cluster.
FEATURE: vminsert: automatically add missing port to -storageNode hostnames. For example, -storageNode=vmstorage1,vmstorage2 is automatically translated to -storageNode=vmstorage1:8400,vmstorage2:8400. This simplifies manual setup of VictoriaMetrics cluster.
FEATURE: add mad(q) function to MetricsQL. It calculates Median absolute deviation for groups of points with identical timestamps across multiple time series.
FEATURE: add outliers_mad(tolerance, q) function to MetricsQL. It returns time series with peaks outside the Median absolute deviation multiplied by tolerance.
FEATURE: add histogram_quantiles("phiLabel", phi1, ..., phiN, buckets) function to MetricsQL. It calculates the given phi*-quantiles over the given buckets and returns time series per each quantile with the corresponding {phiLabel="phi*"} label.
FEATURE: add quantiles_over_time("phiLabel", phi1, ..., phiN, series_selector[d]) function to MetricsQL. It calculates the given phi*-quantiles over raw samples selected by series_selector on the given lookbehind window d. It returns time series per each quantile with the corresponding {phiLabel="phi*"} label.
FEATURE: enterprise: do not ask for -eula flag if -version flag is passed to enteprise app. See this issue.
BUGFIX: properly handle queries with multiple filters matching empty labels such as metric{label1=~"foo|",label2="bar|"}. This filter must match the following series: metric, metric{label1="foo"}, metric{label2="bar"} and metric{label1="foo",label2="bar"}. Previously it was matching only metric{label1="foo",label2="bar"}. See this issue.
BUGFIX: vmselect: reset connection timeouts after each request to vmstorage. This should prevent from cannot read data in 0.000 seconds: unexpected EOF warning in logs. See this issue. Thanks to @mxlxm .
BUGFIX: keep metric name for time series returned from rollup_candlestick function, since the returned series don't change the meaning of the original series. See this issue.
BUGFIX: use Prometheus-compatible label value formatting for count_values function. Previously big values could be improperly formatted, which could break query results, which rely on label value such as ... on(label) count_values("label", ...).
BUGFIX: vmagent: properly use https scheme for wildcard TLS certificates for role: ingress targets in Kubernetes service discovery. See this issue.
BUGFIX: vmagent: support host networking mode for docker_sd_config. See this issue.
BUGFIX: fix non-repeatable results from quantile_over_time() function when the number of input samples exceeds 1000. See this issue.
BUGFIX: vmagent: fix EC2 zone discovery when filters are specified in ec2_sc_config. See this issue.
