v1.132.0

Released at 2025-12-12

• SECURITY: upgrade Go builder from Go1.25.4 to Go1.25.5. See the list of issues addressed in Go1.25.5.

• FEATURE: dashboards/operator: add panels for flags and configuration parameters values. See #1341-operator.

• FEATURE: dashboards/single, dashboards/cluster: add Memory usage breakdown panels to Drilldown section. These panels help analyze overall memory distribution and diagnose anomalies or leaks. See #10139.

• FEATURE: dashboards/single, dashboards/cluster: add Major page faults rate panels to Troubleshooting and Drilldown sections. See #9974

• FEATURE: Influx line protocol data ingestion: reduce CPU and memory usage when parsing Influx lines with escaped chars - ,, \\, = and . See #10053.

• FEATURE: OpenTelemetry data ingestion: reduce CPU usage when parsing metrics received via OpenTelemetry protocol. See 293d809.

• FEATURE: vmagent: add a warning to active targets panel when -dropOriginalLabels=true is set (default), indicating that some debug information may not be available. See #9901.

• FEATURE: vmbackup, vmrestore, vmbackupmanager: add support for SSE KMS Key ID and ACL for use with S3-compatible storages. See #9796. Thanks to @sylr for the contribution.

• FEATURE: vminsert in VictoriaMetrics cluster: improve slowness-based rerouting logic. Now rerouting occurs only for the slowest storage node, and only if the cluster as a whole has enough available capacity to handle the additional load. This prevents unnecessary rerouting when the entire cluster is under heavy load or avoid "rerouting storm". The logic is disabled by default; to enable set -disableRerouting=false. See #9890 for details.

• FEATURE: vmsingle, vmagent: add support of Zabbix Connector ingestion format. See #6087. Thanks to @SinotQ for the contribution.

• FEATURE: vmui: improve legend auto-collapse with a higher threshold, a warning message, and a toggle option. See #10075.

• BUGFIX: all VictoriaMetrics components: properly validate remaining system memory limit. Previously it could have negative values. See #10083.

• BUGFIX: vmalert: don't increase vmalert_alerting_rules_errors_total/vmalert_recording_rules_errors_total for request context cancellation, which may occur during graceful shutdown or group configuration update. See #10128. Thanks to @tIGO for the contribution.

• BUGFIX: vmauth: verify backend network reachability with a TCP dial before marking it healthy. Previously, backends were auto-restored after -failTimeout even if the network was still unreachable, causing requests to hang repeatedly. vmauth now performs a 1s TCP dial check before returning a backend to the healthy pool. See #9997.

• BUGFIX: vmctl: properly handle process termination during prompt confirmation. Previously, termination signal was ignored and process was still waiting for user input. See #10104.

• BUGFIX: vmgateway: properly recover from proxy requests errors. Previously, vmgateway may return empty response.

• BUGFIX: vmsingle and vmstorage in VictoriaMetrics cluster: report stats only for most utilized instances of indexdb/tagFiltersToMetricIDs and indexdb/date_metricID caches. This makes it clear when a cache is full and an action needs to be taken (such as adding more memory or adjusting cache limits). See #10131.

• BUGFIX: vmsingle and vmselect in VictoriaMetrics cluster: disable rollup result cache for instant queries that contain rate function with a lookbehind window larger than -search.minWindowForInstantRollupOptimization. Previously, utilizing the cache might yield incorrect results when time series samples are not continuous. See #10098.

• BUGFIX: vmstorage in VictoriaMetrics cluster: do not wait after closing the last connections from vminsert when shutting down. The bug was introduced in #9487. See #10136.

• BUGFIX: vmsingle and vmstorage in VictoriaMetrics cluster: dateMetricIDCache metrics were renamed to follow the naming pattern used for other caches. vm_date_metric_id_cache_resets_total becomes vm_cache_resets_total{type="indexdb/date_metricID"} and vm_date_metric_id_cache_syncs_total became vm_cache_syncs_total{type="indexdb/date_metricID"}. See #10152.

• BUGFIX: vmsingle and vmstorage in VictoriaMetrics cluster: fix performance degradation caused by redundant indexdb lookups at the start of each hour. See #10114. Thanks to @fxrlv for the contribution.

• BUGFIX: vmsingle and vmstorage in VictoriaMetrics cluster: fix potential datapoint lost in response when query at the last millisecond of the day. See #9804.
