fix(etcd): stop counting canceled watch streams as failed gRPC requests by yankawai · Pull Request #4985 · cozystack/cozystack

europrinter (yankawai) · 2026-10-20T09:14:40Z

What this PR does

The tenant etcd chart has its own copy of etcdHighNumberOfFailedGRPCRequests, and both of its rules count every grpc_code other than OK as a failure. grpc_server_handled_total counts a Watch stream once, when it ends, and the streams of a kube-apiserver that goes away end with Canceled. So whenever an API server on a tenant etcd stops, the Watch method of every member reads as 100 percent failed and the critical rule fires on all of them.

Both rules now count only Unknown|FailedPrecondition|ResourceExhausted|Internal|Unavailable|DataLoss|DeadlineExceeded, the list the etcd mixin has used since etcd-io/etcd#13127 and the one the platform copy in packages/system/monitoring-agents/alerts/etcd.yaml already uses. The grouping BY (job, instance, grpc_service, grpc_method), the thresholds, for and the annotations stay as they are, so the alerts keep their labels.

Seen on a v1.6.5 cluster while a Kubernetes cluster on a tenant etcd was created and deleted a few minutes later. vmalert had the critical alert firing for grpc_method="Watch" on all three members with the value 100. At that point rate(grpc_server_handled_total{grpc_code!="OK"}[10m]) was 0.63 for Watch with Canceled, and the only other non-OK codes were FailedPrecondition on RoleGet and UserGet at 0.0017 each, which is one call each. The same query an hour earlier returned nothing. The platform copy runs in the same vmalert over the same series, and none of the firing alerts came from it. Each alert also showed up seven times there, once per tenant copy of these rules, because the root tenant's vmalert loads the rules of every tenant namespace. This PR does not change that.

hack/etcd-grpc-alerts.bats renders the chart's PrometheusRule with helm template and replays it through vmalert-tool v1.136.0 pinned by digest, the same image #4963 uses. hack/testdata/etcd-grpc-alerts/unittest.yaml has three cases with seven checks. Watch streams that end only with Canceled must not fire at 6, 12 and 30 minutes. Range calls failing with Unavailable at 25 percent must fire the critical rule at 7 minutes and both rules at 12, with the labels and the summary pinned. Both together must fire only for Range. Against the rules on main the suite fails 4 of the 7 checks, all of them on Watch alerts with the value 100. Dropping Unavailable from the list, or grouping by job and instance only, fails 3 checks each.

$ bats hack/etcd-grpc-alerts.bats
1..1
ok 1 tenant etcd failed gRPC request alerts pass their vmalert-tool cases

The same run on the rules from main prints not ok 1 and the four failing checks. With Bats 1.14.0 at the commit CI pins, the suite passes together with bats-strict-setup, bats-no-negated-assert, bats-no-exit-trap, bats-runner-coverage, bats-runner-contract, alert-severity-contract and image-pin-consistency, 81 of 81. Like the migration suites it needs docker, and only the image pull touches the network. Helm 3.17.3 and 4.2.4 render the same rules. I have not run the new rules in vmalert on a live cluster.

The rules file is the same on release-1.6 and release-1.7. The commit cherry-picks onto release-1.6 without conflicts, and that backport is a separate PR with one more commit that drops the load test_helper line, because release-1.6 runs hack/*.bats through hack/cozytest.sh.

Screenshots

Not a UI change.

Downstream repositories

A rule template in packages/extra/etcd, a Bats suite under hack/ and its test data. No values, schema, README, image or ApplicationDefinition change, and the website does not mention these rules, so no trigger map entry applies.

Release note

fix(etcd): the tenant etcd alert etcdHighNumberOfFailedGRPCRequests now counts only the gRPC codes that the etcd mixin and the platform copy of the alert count, so the Canceled watch streams of a Kubernetes API server that stops no longer fire it on every etcd member.

Summary by CodeRabbit

Bug Fixes
- Refined etcd gRPC failure alerts to target specific failure status codes, reducing alerts for non-failure responses while preserving existing thresholds and timing.
- Added coverage for canceled watch streams, unavailable range requests, and combined failure scenarios, including warning and critical alert evaluations.
Tests
- Added integration validation for rendering etcd alert rules and running them through the alert-testing tool, including failure handling when prerequisites are unavailable.

The tenant etcd copy of etcdHighNumberOfFailedGRPCRequests counted every code other than OK. A Watch stream is counted once, when it ends, and the streams of a kube-apiserver that stops end with Canceled. So whenever an API server on that etcd goes away, the Watch method of every member reads as 100 percent failed and the critical rule fires on all of them. The rules now count the codes the etcd mixin counts since etcd-io/etcd#13127, the same list the platform copy in monitoring-agents already uses. The grouping by method stays, so the alert labels do not change. Assisted-by: LLM Signed-off-by: Yan Bondarenko <[email protected]>

📝 Walkthrough

The etcd warning and critical gRPC alerts now match a defined set of failure status codes. New integration tests cover canceled watch streams, unavailable Range calls, and combined scenarios.

Changes: etcd gRPC alert rules

Layer / File(s)	Summary
Filter alert status codes `packages/extra/etcd/templates/prometheus-rules.yaml`	The warning and critical alerts now select specific failure status codes instead of all codes other than `OK`.
Test alert evaluations `hack/testdata/etcd-grpc-alerts/unittest.yaml`, `hack/etcd-grpc-alerts.bats`	The test data covers canceled watch streams, unavailable `Range` calls, and their combination. The Bats test renders the rules and runs `vmalert-tool`.

Clean up the temp directory on every exit path.

The rm -rf "$work" command runs only if every earlier command succeeds. Under bats, a failed helm template or yq command stops the test early, because bats runs tests with set -e. The temp directory then stays on disk. Use teardown or a trap so cleanup always runs.

Approving. Code list is the one etcd mixin uses and the same our platform copy in monitoring-agents/alerts/etcd.yaml already has. Grouping, thresholds and labels stay, so only canceled watch streams stop counting. I ran hack/etcd-grpc-alerts.bats at this head (passes) and with rules from main (fails on Watch alerts at 100).

## What this PR does Backports to `release-1.7` from `main`, picked by the rules of the [backport policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md) in merge order. A merged pull request comes as its own commits, picked with `git cherry-pick -x` so each keeps its author, message and sign-offs, and a merge commit that carries the original's merge message with a `Backported-from:` trailer naming it; a squash-merged one comes as one pick. `backport-batch verify` checks that shape. A pick listed as changed differs from the commit it came from; `git range-diff <merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A conflict or a failing check here is a [backport task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md). -

follow-up: ### Release note ```release-note fix(backupstrategy-controller): the ClickHouse (Altinity) and RabbitMQ backup strategy Pods now run a dedicated `backup-http-client` image (alpine + curl + jq + ca-certificates, non-root, ~7 MB) instead of the 349 MB `platform-migrations` image. Air-gapped mirrors need the new `ghcr.io/cozystack/cozystack/backup-http-client` repository. fix(e2e): a chainsaw assert in the e2e suites keeps polling through a transient API error such as an etcd leader change, instead of failing the suite long before its timeout. fix(ci): use GITHUB_TOKEN to start the initial packages build when freezing a release line fix(etcd): the tenant etcd alert etcdHighNumberOfFailedGRPCRequests now counts only the gRPC codes that the etcd mixin and the platform copy of the alert count, so the Canceled watch streams of a Kubernetes API server that stops no longer fire it on every etcd member. fix(tcp-balancer): HAProxy now takes its fd and thread caps from the replica's memory and CPU limits instead of the node, so a t1.nano balancer is no longer OOMKilled on nodes with many CPUs. maxconn follows the memory limit at about 16 connections per MiB, 2035 on t1.nano, and the pods roll once on upgrade. fix(kubernetes): the Proxmox cloud-controller-manager now runs v0.16.1, and the Proxmox CCM and CSI driver images are pinned by digest. The v0.15.0 tag referenced before was re-pushed upstream to a build that panics on start, which left every new Proxmox worker with the uninitialized taint. fix(marketplace): a tapped repository is pinned to a digest instead of following a mutable tag, so moving the tag upstream no longer changes what runs in the cluster; connect accepts oci://...＠sha256:... and an optional keyless cosign verify policy (anchored to an exact identity and preserved across re-connects), and with verify flags the CLI verifies the signature and pins the verified digest at tap time. fix(dashboard): tenant name in the tenant list links to its detail page now (where Delete is), and top level tenants get their Edit button back. fix(cilium): the IPAM migration hook no longer fails with "Argument list too long" on clusters with more than a few nodes, which blocked the cilium upgrade and every package that depends on networking. fix(kubernetes): the OIDC bootstrap Job no longer fails to start for a tenant cluster with about 240 or more oidc.users, the bindings now come from a ConfigMap the Job mounts. fix(clickhouse): a RestoreJob now restores the archive its Backup was taken as, not the newest one. New Backups record the archive name, Backups taken before this release are restored best effort from the newest archive stamped no later than their takenAt, with a warning in the restore pod log. A ClickHouse BackupJob created again under a name whose Backup still exists now fails instead of reporting that Backup as its result. fix(backups): the backup controller now re-renders the Velero BSL, the default backup strategies and the platform bucket's credentials Secret when their S3 endpoint is stale, so after the platform bucket's BucketAccess is re-granted for a new publishing.host, backups move to the new endpoint without forcing releases by hand. fix(securitygroups): a SecurityGroup with attachments and no rules no longer leaves an invalid CiliumNetworkPolicy behind; its backing policy is now accepted by Cilium and still allows or denies nothing. fix(postgres): the init script renders the declared databases in a stable order, so an upgrade that leaves the databases unchanged no longer rewrites the init-script Secret. fix(mariadb-operator): the MariaDB operator now uses the platform's networking.clusterDomain instead of a hard-coded cozy.local, so replication and User/Database/Grant reconciliation work on clusters with a non-default cluster domain. fix(redis): an instance with `replicas: 1` now runs one Sentinel instead of three, without a Sentinel PodDisruptionBudget; on upgrade, the PDB the operator created earlier is deleted. Instances with two replicas or more are unchanged. fix(lineage, kubernetes): the virt-launcher pods of Kubernetes worker nodes are now resolved to their Kubernetes application and marked as managed by Cozystack, so a SecurityGroup attached to a Kubernetes cluster now applies to its worker nodes, not only to its control plane. fix(api): tenant quota admission now counts the parent pool's usage of extended resources and hugepages, so a child tenant can no longer get a share the parent has already used. After upgrading, updates to existing tenants may be rejected if their quota for these resources exceeds the parent's remaining budget. This includes updates that leave the quota unchanged. fix(postgres): a Postgres BackupJob now fails as soon as its CloudNativePG Backup fails, with the recorded error, instead of after 30 minutes, and a BackupJob waiting on a CloudNativePG Backup reports a WaitingForCNPGBackup condition with the Backup's phase. fix(postgres): databases now refuses the PostgreSQL system databases postgres, template0 and template1, and the init job never runs DROP DATABASE on them. A system database a previous version took over is handed back to the superuser on the next upgrade (event trigger removed, ownership and public schema restored, its <db>_admin and <db>_readonly roles dropped). A release that declares one of them must remove the entry before upgrading. fix(mariadb): a MariaDB BackupJob or RestoreJob whose operator Job failed now ends Failed instead of Succeeded, and a failed backup no longer creates a Ready Backup without an archive. Backups created by failed runs before this fix are not removed; restoring from one can fail or select another dump from the shared prefix. fix(kubernetes, monitoring): the vmagent of tenant Kubernetes clusters now writes to the tenant's vminsert and labels series with the owning tenant instead of `cozy-monitoring`. Previously no tenant cluster metric reached the tenant's Monitoring. ```

## What this PR does Backports to `release-1.7` from `main`, picked by the rules of the [backport policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md) in merge order. A merged pull request comes as its own commits, picked with `git cherry-pick -x` so each keeps its author, message and sign-offs, and a merge commit that carries the original's merge message with a `Backported-from:` trailer naming it; a squash-merged one comes as one pick. `backport-batch verify` checks that shape. A pick listed as changed differs from the commit it came from; `git range-diff <merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A conflict or a failing check here is a [backport task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md). -

COSI driver is bumped to v0.4.0, which writes each grant to per-identity IAM file. ```

## What this PR does On three 3-node clusters running v1.6.4 and v1.6.5 we found a tenant etcd with two of its three members on one node, a tenant Redis with two of its three Sentinels on the node that also ran the master, and several VictoriaMetrics and VictoriaLogs pairs (vmstorage, vmselect, vmalertmanager, vlstorage) sharing a node. Nothing alerted. Losing one of those nodes would have cost the etcd or Sentinel quorum, or both copies of a storage tier. Spread constraints keep new pods apart once they are in place (#4986 for etcd, #4989 for monitoring, #4990 for Redis), but a placement that already exists, or that comes from a soft rule or a drain, stays as it is, because the scheduler does not move running pods. This adds `PodReplicasColocated`, a warning in a new `workload-placement` group under `packages/system/monitoring-agents/alerts/`. It fires when two or more running pods of one StatefulSet, ReplicaSet, CNPG `Cluster` or `StrimziPodSet` have been on one node for an hour while the cluster has at least as many schedulable nodes as the workload has running pods, so five replicas on three nodes stay quiet. The alert carries `cluster`, `namespace`, `owner_kind`, `owner_name` and `node`, plus the `severity`, `exported_instance` and `service` labels the other platform alerts set, and its value is the number of pods on that node. DaemonSets, Jobs and every other owner kind are not in the list, so a DaemonSet surge pod next to its predecessor does not count. etcd-operator gives every member pod its own `EtcdMember` as controller owner ([etcdmember_controller.go#L546](https://github.com/cozystack/etcd-operator/blob/v0.5.6/controllers/etcdmember_controller.go#L546)), so grouping by owner would see one pod per group. Members get their names from `GenerateName: <cluster>-` ([etcdcluster_controller.go#L434](https://github.com/cozystack/etcd-operator/blob/v0.5.6/controllers/etcdcluster_controller.go#L434), [#L839](https://github.com/cozystack/etcd-operator/blob/v0.5.6/controllers/etcdcluster_controller.go#L839)), and members adopted from the old StatefulSet keep names like `etcd-0` ([adopt.go#L103](https://github.com/cozystack/etcd-operator/blob/v0.5.6/internal/migrate/adopt.go#L103)). The rule drops the last dash-separated part of the member name and reports the group as `EtcdCluster <name>`. With the etcd package that is one group per tenant namespace, and two etcd clusters in one namespace would still be told apart. CNPG instance pods carry a controller reference to their `Cluster` ([cluster_create.go#L1580](https://github.com/cloudnative-pg/cloudnative-pg/blob/v1.30.0/internal/controller/cluster_create.go#L1580)), and Strimzi pods one to their `StrimziPodSet` ([StrimziPodSetController.java#L369](https://github.com/strimzi/strimzi-kafka-operator/blob/0.45.1-rc1/cluster-operator/src/main/java/io/strimzi/operator/cluster/operator/assembly/StrimziPodSetController.java#L369)). Owner and node both come from `kube_pod_info`. kube-state-metrics fills `created_by_kind` and `created_by_name` from the controller owner reference and `node` from `spec.nodeName` ([pod.go#L638-L653](https://github.com/kubernetes/kube-state-metrics/blob/v2.15.0/internal/store/pod.go#L638-L653)). `kube_pod_owner` and `kube_pod_status_phase` have no node label of their own, and the kube-state-metrics scrape adds `node` from `__meta_kubernetes_pod_node_name` with `honorLabels: true` (`templates/kube-state-metrics-scrape.yaml`), so on those series `node` is the node of the kube-state-metrics pod. The test data keeps that label on the phase series. A pod counts while `kube_pod_status_phase{phase="Running"}` is 1, so a Failed or Pending pod on the same node does not. `kube_pod_labels` does carry every pod label here (`--metric-labels-allowlist=pods=[*]`), but the rule does not depend on it. A node counts as schedulable unless it has a `NoSchedule` or `NoExecute` taint. A cordon shows up as the `node.kubernetes.io/unschedulable:NoSchedule` taint ([node_lifecycle_controller.go#L549-L555](https://github.com/kubernetes/kubernetes/blob/v1.33.12/pkg/controller/nodelifecycle/node_lifecycle_controller.go#L549-L555)), and not ready and unreachable nodes get theirs from their conditions ([#L87-L99](https://github.com/kubernetes/kubernetes/blob/v1.33.12/pkg/controller/nodelifecycle/node_lifecycle_controller.go#L87-L99)), so one clause covers all three, and a tainted control plane does not count either. Pods that a drain had to put together on the remaining nodes therefore stay quiet while the node is out, and the hour starts once it is back. The alert waits an hour. A replacement pod runs next to its terminating predecessor only for the predecessor's grace period, and node maintenance takes the drained node out of the count, while a placement that has held for an hour does not fix itself. The alert is about a risk rather than an outage, so the wait costs nothing. The VMAlert sets both `remoteWrite` and `remoteRead`, so the pending state survives a vmalert restart ([vmalert docs](https://docs.victoriametrics.com/victoriametrics/vmalert/#alerts-state-on-restarts)). Not covered are workloads that run one pod per owner, such as ClickHouse with one StatefulSet per replica ([patterns.go#L45-L53](https://github.com/Altinity/clickhouse-operator/blob/release-0.25.2/pkg/model/chi/namer/patterns.go#L45-L53)) and the KubeVirt VMs behind a tenant Kubernetes node group. They would need grouping by pod labels, which this rule avoids. The node count is cluster-wide, so a workload that a node selector or affinity restricts to fewer nodes than it has pods fires too. `hack/workload-placement-alerts.bats` takes `.spec` of the VMRule and replays it through `vmalert-tool` v1.136.0 pinned by digest, the release vm-operator v0.68.4 deploys by default ([config.go#L38](https://github.com/VictoriaMetrics/operator/blob/v0.68.4/internal/config/config.go#L38)) and the same image #4963 and #4985 use. `hack/testdata/workload-placement-alerts/unittest.yaml` has 13 cases with 24 checks. Two of three StatefulSet pods on one node fire at 61 minutes and not at 59, with labels and annotations pinned. Spread pods, five ReplicaSet pods on three nodes, a DaemonSet surge pod, two pods of one Job, a Failed pod next to a running one, and one pod each in two clusters that share workload and node names stay quiet. etcd members fire as one `EtcdCluster` per namespace, for generated and adopted member names. A replacement pod next to its terminating predecessor for twenty minutes stays quiet, and the same overlap held past the hour fires and resolves when it ends. A cordoned node keeps the alert quiet until it is uncordoned, and a node with unreachable taints keeps it quiet throughout. ReplicaSet, CNPG `Cluster` and `StrimziPodSet` pods fire with their owner kind. ```console $ bats hack/workload-placement-alerts.bats 1..1 ok 1 workload placement alerts pass their vmalert-tool cases ``` With the expression replaced by one that never fires, the suite prints `not ok 1` and vmalert-tool reports 5 of the 24 checks, which are all the checks that expect an alert. On main, where the rule file does not exist, the suite fails as well. Each of these changes to the rule fails at least one check, with the number of failing checks in brackets. `for: 15m` (5), no phase filter (1), no node count (6), no `cluster` label (6), DaemonSet and Job in the kind list (3), no taint clause (4), `<` instead of `<=` (5), etcd members grouped per member (1). With Bats 1.14.0 at the commit CI pins, the suite passes together with `alert-severity-contract`, `bats-strict-setup`, `bats-no-negated-assert`, `bats-no-exit-trap`, `bats-runner-coverage`, `bats-runner-contract`, `image-pin-consistency` and `check-commit-trailers`, 109 of 109, and the severity contract lists the new alert as `warning`. helm-unittest 1.1.2, the version CI pins, passes the monitoring-agents chart with 19 of 19 tests in 6 suites, and `helm template` with Helm 3.17.3 renders the VMRule the same as the file. Like the migration suites the new suite needs docker, and only the image pull touches the network. I have not run the rule in vmalert on a live cluster. On release-1.6 kube-state-metrics 2.15.0, its scrape config, the alerts template, the VMAlert and vm-operator v0.68.4 are the same, and etcd-operator v0.5.5 and CNPG 1.28.2 set the same owners and member names. The new files apply there without changes. That backport is a separate PR with one more commit that drops the `load test_helper` line, because release-1.6 runs `hack/*.bats` through `hack/cozytest.sh`. ### Screenshots Not a UI change. ### Downstream repositories A new alert file under `packages/system/monitoring-agents/alerts/`, a Bats suite under `hack/` and its test data. No values, schema, README, image or `ApplicationDefinition` change, and the website does not list platform alerts by name, so no trigger map entry applies. - [x] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note feat(monitoring): new warning alert PodReplicasColocated fires when two or more running pods of one StatefulSet, ReplicaSet, CNPG Cluster, StrimziPodSet or etcd cluster have shared a node for an hour while the cluster has a schedulable node for each of them. ```  ## Summary by CodeRabbit * **New Features** * Added monitoring for workloads whose running pod replicas are colocated on the same node. * Alerts include workload, node, cluster, and severity details, along with quorum-loss guidance. * Coverage includes StatefulSets, ReplicaSets, Clusters, StrimziPodSets, and EtcdMembers. * **Tests** * Added validation for workload-placement alerts across scheduling, availability, cluster-isolation, and pod-replacement scenarios.
