VictoriaMetrics

v1.143.0

Released at 2026-05-08

• SECURITY: upgrade Go builder from Go1.26.2 to Go1.26.3. See the list of issues addressed in Go1.26.3.

• FEATURE: all VictoriaMetrics components: suppress TCP health check errors when -tls flag is set. See #10538.

• FEATURE: vmagent and vmsingle: add __meta_hetzner_robot_datacenter label for robot role in hetzner_sd_configs. See #10909. Thanks to @juliusrickert for contribution.

• FEATURE: vmalert: add -rule.stripFilePath to support stripping rule file paths in logs and all API responses, including /metrics. See #5625.

• FEATURE: vmalert: add formatTime template function for formatting a Unix timestamp using the provided layout. For example, {{ now | formatTime "2006-01-02T15:04:05Z07:00" }} returns the current time in RFC3339 format. See issue #10624. Thanks to @andriibeee for the contribution.

• FEATURE: vmagent, vmsingle, vminsert in VictoriaMetrics cluster: add support for Prometheus native histogram during ingestion. See #10743.

• FEATURE: vmagent, vmsingle, vmselect in VictoriaMetrics cluster and vmstorage in VictoriaMetrics cluster: introduce the vm_fs_info metric. It exposes the filesystem type (e.g., ext4, xfs, nfs) used for -*Path related flags. See #10482.

• FEATURE: dashboards/vmagent: add Kafka (Enterprise) row with panels for monitoring traffic (bytes), messages in/out, producer and consumer errors. See #10728.

• BUGFIX: vmagent and vmsingle: properly obtain __meta_hetzner_hcloud_location and __meta_hetzner_hcloud_location_network_zone labels for hetzner_sd_configs. Hetzner changed discovery API response and returns location information from different field. See #10909. Thanks to @juliusrickert for contribution.

• BUGFIX: vminsert in VictoriaMetrics cluster: properly discover addresses of storage nodes with enterprise automatic-vmstorage-discovery. Bug was introduced at v1.141.0.

• BUGFIX: vmauth: now correctly respects disabling retries via -maxRequestBodySizeToRetry=0. Previously, disabling retries required setting both -maxRequestBodySizeToRetry and -requestBufferSize to 0. See #10857. Thanks to @andriibeee for the contribution.

• BUGFIX: vmbackupmanager: explicitly set the MD5 checksum for DeleteObjects requests. Starting with aws-sdk-go-v2/service/s3 v1.73.0, the SDK switched the checksum algorithm from MD5 to CRC32, which can break compatibility with some third-party S3 implementations, including Dell ECS. See #10907.

• BUGFIX: vmauth: attempt to route requests to the first backend when all backends are marked as broken. Previously, vmauth returned an error immediately without attempting any backend. This change may improve success rate in rare edge cases. See #10837.

• BUGFIX: vmsingle: and vmselect in VictoriaMetrics cluster: give priority to extra_label and extra_filters[] params defined in URL query string over those defined in request body form, to properly respect constraints imposed by vmauth. See #10908.

• BUGFIX: vmsingle and vmselect in VictoriaMetrics cluster: set CORS headers on /api/v1/export, /api/v1/export/csv and /api/v1/export/native. See #10899. Thanks to @andriibeee for the contribution.
