* FEATURE: add the following functions to [MetricsQL](https://victoriametrics.github.io/MetricsQL.html):
|
||||||
|
- `histogram_avg(buckets)` - returns the average value for the given buckets.
|
||||||
|
- `histogram_stdvar(buckets)` - returns standard variance for the given buckets.
|
||||||
|
- `histogram_stddev(buckets)` - returns standard deviation for the given buckets.
|
||||||
|
* FEATURE: vmagent: add ability to replicate scrape targets among `vmagent` instances in the cluster with `-promscrape.cluster.replicationFactor` command-line flag. See [these docs](https://victoriametrics.github.io/vmagent.html#scraping-big-number-of-targets).
|
||||||
|
* FATURE: vmagent: accept `scrape_offset` option at `scrape_config`. This option may be useful when scrapes must start at the specified offset of every scrape interval. See [these docs](https://victoriametrics.github.io/vmagent.html#troubleshooting) for details.
|
||||||
|
* FEATURE: vmauth: allow using regexp paths in `url_map`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1112) for details.
|
||||||
|
|
||||||
|
* BUGFIX: vmagent: prevent from high CPU usage bug during failing scrapes with small `scrape_timeout` (less than a few seconds).
|
||||||
|
* BUGFIX: vmagent: reduce memory usage when Kubernetes service discovery is used in big number of distinct jobs by sharing the cache. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113
|
||||||
|
* BUGFIX: prevent exponent overflow when processing extremely small values close to zero such as `2.964393875E-314`. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1114
