 ## tip

+## [v1.145.0](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/tag/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](https://github.com/golang/go/issues?q=milestone%3AGo1.26.4%20label%3ACherryPickApproved).

+* FEATURE: [enterprise](https://docs.victoriametrics.com/enterprise/) [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) and `vmstorage` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): 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](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10960)
 * FEATURE: [vmalert](https://docs.victoriametrics.com/victoriametrics/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](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11020).
 * FEATURE: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/), [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) and `vminsert` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): add `-opentelemetry.promoteAllResourceAttributes` and `-opentelemetry.promoteScopeMetadata` command-line flags to allow managing label promotion for resource attributes and OTel scope metadata. See [OpenTelemetry](https://docs.victoriametrics.com/victoriametrics/integrations/opentelemetry/) docs and [#10931](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10931).
 * FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent/) : introduce `vmagent_remotewrite_kafka_outbuf_latency_seconds` and  `vmagent_remotewrite_kafka_rtt_seconds` metrics for [kafka integration](https://docs.victoriametrics.com/victoriametrics/integrations/kafka/). The metrics could help identify throughput bottlenecks. See [#10730](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10730).
 * FEATURE: [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/): properly log user information when a missing route error occurs. See [#11052](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/11052).
-* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl/): add the ability to migrate data from Mimir object storage to VictoriaMetrics. See [#7717](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7717). 
+* FEATURE: [vmctl](https://docs.victoriametrics.com/vmctl/): add the ability to migrate data from [Mimir](https://docs.victoriametrics.com/victoriametrics/vmctl/mimir/#) object storage to VictoriaMetrics. See [#7717](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7717). 
+* FEATURE: [dashboards](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/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](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/11047).

 * BUGFIX: [vmalert](https://docs.victoriametrics.com/victoriametrics/vmalert/): fix the `Notifiers` page in web UI appearing blank despite the API returning notifier data correctly. See [#11035](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11035).
 * BUGFIX: [vmalert](https://docs.victoriametrics.com/victoriametrics/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](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10985).
 * BUGFIX: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/) and [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/): properly parse [Prometheus Native Histograms](https://prometheus.io/docs/specs/native_histograms/), previously Protobuf parser could produce unexpected `vmrange` labels. See [#11041](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/11041).
-* BUGFIX: [vmauth](https://docs.victoriametrics.com/victoriametrics/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.

Previously, it was only accounting for static users and skipped JWT configuration entries. See [#11050](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/11050/).
 * BUGFIX: [MetricsQL](https://docs.victoriametrics.com/victoriametrics/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](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9474). Thanks to @wtfashwin for contribution.
-* BUGFIX: `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): avoid returning HTTP 503 for queries with partial results when a storage group is unavailable and `-search.denyPartialResponse` is disabled.

See [#10968](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10968).
 * BUGFIX: [vmui](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#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](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/11004). Thanks to @immanuwell for the contribution.
+* BUGFIX: `vmselect` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): fix intermittent `write: connection timed out` errors caused by silently dropped TCP connections being reused from the connection pool. See [#10735](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10735#issuecomment-4535832301).

Nikolay	4cb5fae347	lib/storage: add scheduled rows metrics for calculation background merge completion (#1048 ) Previously, only the size and number of partitions were exposed as metrics. It's not enough to estimate the possible completion time. New metrics `vm_downsampling_partitions_scheduled_rows` and `vm_retention_filters_partitions_scheduled_rows` allow predicting completion time by the following query: ``` sum(vm_downsampling_partitions_scheduled_rows) / sum(rate(vm_rows_merged_total{type="storage/big"})) ``` and ``` sum(vm_retention_filters_partitions_scheduled_rows) / sum(rate(vm_rows_merged_total{type="storage/big"})) ``` Note, `vm_rows_merged_total` accounts for all possible merges, and it could slightly overestimate completion time.

Max Kotliar	42c1f729db	dashboards: show short_version when available, fall back to long version otherwise (#11047 ) The `Version` panel shows an empty value when a service is built from a feature branch. In such cases, `short_version` label is not available, so `by(job, short_version)` grouping produces no visible value in the panel. Previously, to see the actual version, one had to manually edit the panel query and add the relevant `version` label to the `by()` clause. The fix tries `short_version` and when empty falls back to a long `version` label. This is applied uniformly across all dashboards: - victoriametrics (single-node) - victoriametrics-cluster - vmagent - vmalert - vmauth - operator PR simplifies debugging with custom or feature-branch builds.	2026-06-04 17:28:25 +03:00
Max Kotliar	6851a75c71	lib/netutil: detect silently dropped idle TCP connections before reuse (#11024 ) Fixes https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10735 Related to https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10646 Connections silently dropped at the network layer (no RST/FIN) remain alive from the OS perspective until TCP_USER_TIMEOUT fires. It happens while the connection stays in the pool. When such a stale connection is reused from the pool, the next write fails immediately (<100 microseconds) with a `write: connection timed out` error. Since timeout errors are not retriable, it results in a user-visible query error like: ``` cannot flush requestData to conn: write tcp4 ...: write: connection timed out ``` Before returning a pooled connection to a caller, probe it with a non-blocking read, but only if it has been idle for 5 or more seconds. Fresh connections (idle < 5s) are returned without an extra alive check to avoid unnecessary overhead on the fast path. The alive probe sets ReadDeadline=now+5ms and reads 1 byte. A deadline-exceeded error means the connection is alive. Any other result (EOF, ETIMEDOUT, unexpected data) means the connection is dead, and it is discarded. PR https://github.com/VictoriaMetrics/VictoriaMetrics/pull/11024 This is useful for deployments with unstable network infrastructure, where established connections can be silently broken while sitting in the pool. When in doubt if it's your case or not, look for `write: connection timed out` errors in logs, or monitor the error ratio with: ``` sum( increase(vm_request_errors_total{action="search",type="rpcClient",name="vmselect"}[1m]) ) by (job) / sum( increase(vm_requests_total{action="search",type="rpcClient",name="vmselect"}[1m]) ) by (job) * 100 ```	2026-06-04 17:13:44 +03:00
