VictoriaMetrics

v1.146.0

Released at 2026-06-19

• FEATURE: all VictoriaMetrics components: add -http.header.disableServerHostname command-line flag for disabling the X-Server-Hostname HTTP response header. See #11067. Thanks to @zasdaym for contribution.

• FEATURE: vmsingle and vmselect in VictoriaMetrics cluster: log calls to /api/v1/admin/tsdb/delete_series API handler. This should help to identify events of metrics deletion from the database. See #11104.

• FEATURE: vmctl: add -vm-headers and -vm-bearer-token flags for authenticating requests to the VictoriaMetrics import destination. The flags are available in opentsdb, influx, remote-read, prometheus, mimir, and thanos vmctl sub-commands. See #8897.

• FEATURE: vmui: add the last value to graph legend statistics. See #10759.

• FEATURE: stream aggregation: expose vm_streamaggr_dedup_dropped_samples_total to allow tracking dropped old samples during deduplication.

• FEATURE: stream aggregation: use the aggregation rule interval as the default staleness_interval instead of 2*interval, to reduce spikes when there are gaps between received samples. See #11102.

• FEATURE: vmagent: add a new flag -remoteWrite.inmemoryQueues to prioritize recently ingested data over historical data stored at file-based persistent queue. See #8833

• FEATURE: vmagent: add -promscrape.cluster.shardByLabels command-line flag for selecting target labels used for sharding scrape targets among vmagent instances in cluster mode. See #11044.

• FEATURE: vmctl: add -vm-headers and -vm-bearer-token flags for authenticating requests to the VictoriaMetrics import destination. The flags are available in opentsdb, influx, remote-read, prometheus, mimir, and thanos vmctl sub-commands. See #8897.

• FEATURE: vmsingle and vmselect in VictoriaMetrics cluster: log calls to /api/v1/admin/tsdb/delete_series API handler. This should help to identify events of metrics deletion from the database. See #11104.

• FEATURE: vmui: add the last value to graph legend statistics. See #10759.

• BUGFIX: enterprise vmsingle and vmstorage in VictoriaMetrics cluster: properly expose metric vm_retention_filters_partitions_scheduled_rows. See #11138

• BUGFIX: stream aggregation: fix issue with producing aggregated samples with identical timestamps between flushes. See #10808.

• BUGFIX: vmagent: fix potential corruption of remote-write metadata Unit values. See #11120. Thanks for @fxrlv for the contribution.

• BUGFIX: vmalert,vmauth,vmagent and vmsingle: fix rare unbounded shutdown delay when config reload takes longer than -configCheckInterval. See #11107. Thanks to @PleasingFungus for contribution.

• BUGFIX: vmbackup, vmbackupmanager: do not fail backup list if directory is absent while using fs:// destination to align with other protocols. See 6c3c548d.

• BUGFIX: vmctl: push metrics to configured -pushmetrics.url on shutdown when migration fails. Previously, metrics were not pushed if vmctl exited with an error. See #11081. Thanks to @zasdaym for contribution.

• BUGFIX: vmrestore: disallow restoring parts outside the configured -storageDataPath directory. See 710c920d.

• BUGFIX: vmselect in VictoriaMetrics cluster: correctly apply long tenant filters. Previously, such filters could be truncated, causing tenants to be matched incorrectly. See #11096. Thanks for @fxrlv for the contribution.

• BUGFIX: vmselect in VictoriaMetrics cluster: fix corrupted metrics metadata when a response contains multiple rows. See #11115. Thanks for @fxrlv for the contribution.

• BUGFIX: vmselect in VictoriaMetrics cluster: don't cache empty responses for tenant IDs discovery during multitenant queries. This problem was visible during integration tests when multitenant queries were executed before the first ingestion happened. See #10982

• BUGFIX: vmsingle and vmselect in VictoriaMetrics cluster: properly escape metricFamilyName at metrics metadata response. See #11129. Thanks for @fxrlv for the contribution.

• BUGFIX: vmsingle and vmstorage in VictoriaMetrics cluster: prevent more cases of panic during directory deletion on NFS-based mounts. See #11060.
