VictoriaMetrics/VictoriaMetrics v1.64.0 on GitHub

Changes

FEATURE: add support for Prometheus staleness markers. See this issue.
FEATURE: vmagent: automatically generate Prometheus staleness markers for the scraped metrics when scrape targets disappear in the same way as Prometheus does. See this issue.
FEATURE: add present_over_time(m[d]) function, which returns 1 if m has a least a single sample over the previous duration d. This function has been added also to Prometheus 2.29.
FEATURE: vmagent: support multitenant writes according to these docs. This allows using a single vmagent instance in front of VictoriaMetrics cluster for all the tenants. Thanks to @omarghader for the pull request. See this issue.
FEATURE: vmagent: add __meta_ec2_availability_zone_id label to discovered Amazon EC2 targets. This label is available in Prometheus starting from v2.29.
FAETURE: vmagent: add __meta_gce_interface_ipv4_<name> labels to discovered GCE targets. These labels are available in Prometheus starting from v2.29.
FEATURE: add -search.maxSamplesPerSeries command-line flag for limiting the number of raw samples a single query can process per each time series. This option can protect from out of memory errors when a query processes tens of millions of raw samples per series. See this issue.
FEATURE: add -search.maxSamplesPerQuery command-line flag for limiting the number of raw samples a single query can process across all the time series. This option can protect from heavy queries, which select too big number of raw samples. Thanks to @jiangxinlingdu for the initial pull request.
FEATURE: improve performance for queries that process big number of time series and/or samples on systems with big number of CPU cores.
FEATURE: vmalert: expose vmalert_alerting_rules_last_evaluation_samples and vmalert_recording_rules_last_evaluation_samples metrics. See this issue.
FEATURE: vminsert: expose vm_rpc_send_duration_seconds_total counter, which can be used for determining high saturation of every vminsert -> vmstorage link with an alerting query rate(vm_rpc_send_duration_seconds_total) > 0.9s. This query triggers when the link is saturated by more than 90%. This usually means that more vminsert or vmstorage nodes must be added to the cluster in order to increase the total number of vminsert -> vmstorage links.
FEATURE: vmagent: expose vmagent_remotewrite_send_duration_seconds_total counter, which can be used for determining high saturation of every connection to remote storage with an alerting query rate(vmagent_remotewrite_send_duration_seconds_total) > 0.9s. This query triggers when a connection is satureated by more than 90%. This usually means that -remoteWrite.queues command-line flag must be increased in order to increase the number of connections per each remote storage.
FEATURE: vmui: automatically fill Server URL field. See this issue.
BUGFIX: fix corner cases for queries on time ranges exceeding 40 days. Previously some series can be missing in query results. See this issue.
BUGFIX: vmselect: return dummy response at /rules page in the same way as for /api/v1/rules page. The /rules page is requested by Grafana 8. See this issue for details.
BUGFIX: vmbackup: automatically set default us-east-1 S3 region if it is missing. This should simplify using S3-compatible services such as MinIO for backups. See this issue.
BUGFIX: vmselect: prevent from possible deadlock when multiple target query args are passed to Graphite Render API.
BUGFIX: return series with a op b labels and N values for (a op b) default N if (a op b) returns series with all NaN values. Previously such series were removed.
BUGFIX: vmui: fix layout when the query selects more than 27 time series. See this issue.
BUGFIX: vmagent: restore red highlighting for DOWN targets at /targets page. See this issue.
