v1.134.0 #

Released at 2026-01-16

SECURITY: upgrade Go builder from Go1.25.5 to Go1.25.5. See the list of issues addressed in Go1.25.6 .
FEATURE: dashboards/single : refine VictoriaMetrics - single dashboard and aligned it with the VictoriaMetrics - cluster dashboard. For the full list of changes see #10132-comment and #10260 .
FEATURE: vmagent : add vm_persistentqueue_free_disk_space_bytes metric for vmagent’s persistent queue capacity. See #10193 .
FEATURE: vmsingle and vmselect in VictoriaMetrics cluster : expose vm_rollup_result_cache_requests_total which tracks the number of requests to the query rollup cache. See #10117 .
FEATURE: vmauth : add a metric vmauth_http_request_errors_total{reason="client_canceled"} to measure client cancelled requests. This should help with debugging vmauth issues. See #10233 .
FEATURE: vmauth : do not retry client canceled requests. See #10233 .
FEATURE: vmsingle and vmstorage in VictoriaMetrics cluster : add explicit month duration unit (M) for -retentionPeriod flag. This allows users to specify retention periods in months more explicitly. See #10181 .
FEATURE: dashboards/vmagent : add Persistent queue Full ETA panel to the Drilldown section. This panel helps estimate how much time remains until vmagent starts dropping incoming metrics. See #10193 .
FEATURE: vmalert : add support for $isPartial variable in alerting rule annotation templating . This allows users to include an additional warning message in alerts triggered by partial query responses. See #4531 .
FEATURE: vmsingle and vmselect in VictoriaMetrics cluster : calculate the lookbehind window as the median of the intervals between the last 20 raw samples within the requested time range for range queries. Previously, this calculation was based on the first 20 samples, using the last 20 samples should improve accuracy for recent data. See #10281 .
BUGFIX: vmagent : fix configuration reloading for -remoteWrite.relabelConfig and -remoteWrite.urlRelabelConfig when vmagent is launched with empty files. Previously, if vmagent started with an empty config, subsequent config reloads were ignored. See #10211 .
BUGFIX: vmsingle and vmstorage in VictoriaMetrics cluster : prevent slow ingestion requests and CPU usage spikes during midnight daily-index creation. See #10064 .
BUGFIX: vmsingle : fix a missing path error for http://<victoriametrics-addr>:8428/zabbixconnector/api/v1/history. See 10214 .
BUGFIX: vmstorage in VictoriaMetrics cluster : reduce default value for storage.vminsertConnsShutdownDuration flag from 25s to 10s seconds. It reduces probability of ungraceful storage shutdown at Kubernetes based environments, which has 30 seconds default graceful termination period value. See #10273
BUGFIX: vmui : remove legacy tenantID query param and use the URL path as the single source of truth for multitenancy. See #10232 .
BUGFIX: vmui : fix heatmap rendering issues where charts could break or appear empty when bucket values were uniform or sparse. See #10240 .
BUGFIX: all VictoriaMetrics components: prefer numerical values over stale markers when samples share the same timestamp during deduplication. See #10196 .
BUGFIX: vmstorage in VictoriaMetrics cluster : correctly return results for /api/v1/labels and /api/v1/label/{}/values when match[], extra_filters or extra_labels are specified. See #10294

v1.133.0 #

Released at 2026-01-02

Update Note 1: vmsingle and vmstorage in VictoriaMetrics cluster : Upgrading to per-partition index requires registering all active time series. Expect slow down of data ingestion and queries during upgrade roll-out. This is a one-time operation. Additionally, for users with retention periods shorter than 1 month the disk usage may increase.

SECURITY: upgrade base docker image (Alpine) from 3.22.2 to 3.23.2. See Alpine 3.23.2 release notes .
FEATURE: vmagent and vmsingle : add support for global sampleLimit setting. This allows users to efficiently limit the number of samples accepted per scrape target. This also ensures target-level sample_limit can correctly override the global setting. See #10145 . Thanks to @kobylyanskiy for the contribution.
FEATURE: vmauth : expose vmauth_user_request_backend_requests_total and vmauth_unauthorized_user_request_backend_requests_total metrics , which track the number of requests sent to backends. These counts may exceed vmauth_user_requests_total and vmauth_unauthorized_user_requests_total when requests are retried across multiple backends. See #10171 .
FEATURE: vmauth : expose vmauth_user_request_errors_total and vmauth_unauthorized_user_request_errors_total metrics , which track the number of user request errors. See #10188 .
FEATURE: vmauth : add -maxQueueDuration command-line flag for waiting until the incoming request could be executed if -maxConcurrentRequests are already exceeded. This should help with graceful handling of a short spike in the number of concurrent requests without leading to a retry storm. See #10078 .
FEATURE: vmsingle and vmstorage in VictoriaMetrics cluster : introduce per-partition index. This should reduce disk space occupied by indexDBs as they get deleted along with the corresponding partitions once those partitions become outside the retention window. Read more about the motivation behind this feature at #7599 and what to expect at #8134 .
BUGFIX: vmagent and vmsingle : properly add exported_ prefix to scraped metrics that have the same names as auto-generated metrics . Previously, some auto-generated metrics were not recognized, so scraped metrics with the same names could overwrite them. See #10197 . Thanks to @fxrlv for the contribution.
BUGFIX: vmagent : fix vmagent_rows_inserted_total{type="newrelic"} metric to correctly count samples. See #10191 . Thanks to @fxrlv for the contribution.
BUGFIX: vmauth : fix vmauth_user_request_backend_errors_total and vmauth_unauthorized_user_request_backend_errors_total to only reflect backend request errors. Previously, these counters could be overcounted with user request error. See #10177 .
BUGFIX: vmsingle and vmstorage in VictoriaMetrics cluster : rotate dateMetricIDCache instead of resetting it. This should make the eviction less aggressive. Since the cache does not have fixed max size anymore the -storage.cacheSizeIndexDBDateMetricID flag has been removed. See #10064 and PR #10169 .
BUGFIX: vmsingle : properly add metrics metadata scraped with promscrape.config and selfScrapeInterval. See #10175 .
BUGFIX: vmsingle and vmstorage in VictoriaMetrics cluster : fix stats collection for indexdb/tagFiltersToMetricIDs, indexdb/metricID, and indexdb/date_metricID caches. As per PR #10131 , the stats is collected for most utilized instance only, but if the size of all instances is 0 then the stats won’t be collected at all. This may result in max cache size alternating between the actual value and 0. See #10204 and #10230 .
BUGFIX: vmsingle and vmselect in VictoriaMetrics cluster : properly proxy requests to vmalert when -vmalert.proxyURL flag is set. See #10178 .
