VictoriaMetrics

v1.145.0

Release candidate

• SECURITY: upgrade Go builder from Go1.26.3 to Go1.26.4. See the list of issues addressed in Go1.26.4.

• FEATURE: enterprise vmsingle and vmstorage in VictoriaMetrics cluster: add the new metrics vm_downsampling_partitions_scheduled_rows and vm_retention_filters_partitions_scheduled_rows for measuring background historical data merge completion time. See #10960

• FEATURE: vmalert: support match[]=<label_selector> query parameters in /api/v1/rules and /api/v1/alerts APIs to return only the rules that have configured labels satisfying the provided label selectors. See 11020.

• FEATURE: vmagent, vmsingle and vminsert in VictoriaMetrics cluster: add -opentelemetry.promoteAllResourceAttributes and -opentelemetry.promoteScopeMetadata command-line flags to allow managing label promotion for resource attributes and OTel scope metadata. See OpenTelemetry docs and #10931.

• FEATURE: vmagent : introduce vmagent_remotewrite_kafka_outbuf_latency_seconds and vmagent_remotewrite_kafka_rtt_seconds metrics for kafka integration. The metrics could help identify throughput bottlenecks. See #10730.

• FEATURE: vmauth: properly log user information when a missing route error occurs. See #11052.

• FEATURE: vmctl: add the ability to migrate data from Mimir object storage to VictoriaMetrics. See #7717.

• FEATURE: dashboards: show the full version label in the Version panel when short_version label is empty (e.g. custom builds from feature branch). Previously, the panel could appear empty. See #11047.

• BUGFIX: vmalert: fix the Notifiers page in web UI appearing blank despite the API returning notifier data correctly. See #11035.

• BUGFIX: vmalert: reset the group evaluation timestamp if it exceeds the current host time. Previously, vmalert could use future timestamps for evaluations if the system clock was shifted backward. See #10985.

• BUGFIX: vmagent and vmsingle: properly parse Prometheus Native Histograms, previously Protobuf parser could produce unexpected vmrange labels. See #11041.

• BUGFIX: vmauth: properly calculate number of loaded users to be printed in startup log. Previously, it was only accounting for static users and skipped JWT configuration entries. See #11050.

• BUGFIX: MetricsQL: integrate() no longer extrapolates the last sample's value past the end of the time series. Previously, querying integrate(metric[1h]) at a timestamp where the series had already ended would keep accruing area as if the last value continued indefinitely, producing values much larger than the true integral. See #9474. Thanks to @wtfashwin for contribution.

• BUGFIX: vmselect in VictoriaMetrics cluster: avoid returning HTTP 503 for queries with partial results when a storage group is unavailable and -search.denyPartialResponse is disabled. See #11009. Thanks to @fxrlv for the contribution.

• BUGFIX: vmsingle and vmselect in VictoriaMetrics cluster: properly escape utf-8 label names for /federate API requests. See #10968.

• BUGFIX: vmui: persist the Disable deduplication toggle under its own local storage key. Before this fix, the toggle state was lost after reload and could overwrite the Compact view table setting. See #11004. Thanks to @immanuwell for the contribution.

• BUGFIX: vmselect in VictoriaMetrics cluster: fix intermittent write: connection timed out errors caused by silently dropped TCP connections being reused from the connection pool. See #10735.
