fix(monitoring): send alerts to every Alertmanager replica - #4889
myasnikovdaniil merged 1 commit into
Conversation
vmalert had a single notifier, the headless vmalertmanager-alertmanager Service. It resolves to all three pods, but each alert reached one replica at a time and moved to another when vmalert reconnected. On clusters running 1.6.4 all active alerts sat on one replica while the other two had none, and on one of them the alert count of each replica changed about 170 times a day. The Alertmanager cluster deduplicates notifications only when every replica receives every alert. The replica an alert left let it expire and sent a resolved notification, and the replica it reached sent a new firing one. vmalert now lists each Alertmanager pod as its own notifier, using the <name>-<i>.<service>.<namespace>.svc address the operator itself gives StatefulSet pods. The replica count comes from one helper that also sets spec.replicaCount of the VMAlertmanager, so the two cannot drift. Assisted-by: LLM Signed-off-by: Yan Bondarenko <[email protected]>

There was a problem hiding this comment.
Checked this against a live Alertmanager StatefulSet. The governing Service is headless and its pods use the same per-pod names that --cluster.peer already has (vmalertmanager-alertmanager-<i>.vmalertmanager-alertmanager.<ns>), so the notifier addresses resolve the same way the replicas find each other. The live VMAlert still has the single Service notifier, so the problem described here is real.
Rendered the chart before and after with two metric storages. The only difference is the three notifier URLs in the VMAlert, replicaCount of the VMAlertmanager stays 3. helm unittest passes, 24 suites and 304 tests. I found no other place in the charts that points at the shared Service.
Approving. One thing to know, not blocking: the headless Service publishes not ready addresses, so while a replica restarts vmalert still tries its address and logs errors for that notifier, the other two keep receiving alerts.
…ager replica (#4890) ## What this PR does Backport of #4889 to `release-1.6`. The commit is cherry-picked from 9d4221b. The only conflict was in `templates/_helpers.tpl`, which is shorter on this branch, so the new `monitoring.alertmanager.replicas` helper is appended to the release-1.6 file and nothing else from main comes along. The vmalert and VMAlertmanager templates here are the same as on main before the fix, a single notifier on the shared Service and `replicaCount: 3`, so the change applies as is. The monitoring chart tests pass on this branch, 7 suites and 50 tests, the new suite included. ### Screenshots Not a UI change. ### Downstream repositories - [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: Same diff as #4889, two templates, the helpers and a test file of `packages/system/monitoring`, so no trigger map entry applies. ### Release note ```release-note fix(monitoring): vmalert now sends alerts to every Alertmanager replica instead of the shared Service, so the Alertmanager cluster deduplicates them and a long-running alert no longer produces repeated firing and resolved notifications. ```
…ager replica (#4943) ## What this PR does Backport of #4889 to `release-1.7`. The branch was cut on October 12, two days before #4889 merged, so its vmalert still sends to the shared Service and an upgrade from 1.6.5 to 1.7.0 would bring the bug back. The commit is cherry-picked from 9d4221b without conflicts, and after it the monitoring chart here is identical to main. The monitoring chart tests pass on this branch, 24 suites and 304 tests, the new suite included. Without the fix the new suite fails, 2 of 3 tests. ### Screenshots Not a UI change. ### Downstream repositories - [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: Same diff as #4889, two templates, the helpers and a test file of `packages/system/monitoring`, so no trigger map entry applies. ### Release note ```release-note fix(monitoring): vmalert now sends alerts to every Alertmanager replica instead of the shared Service, so the Alertmanager cluster deduplicates them and a long-running alert no longer produces repeated firing and resolved notifications. ```

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
vmalert sends every alert to every Alertmanager replica instead of to the shared Service.
The chart gave vmalert a single notifier,
http://vmalertmanager-alertmanager.<namespace>.svc:9093. That Service is headless and resolves to the three Alertmanager pods, but each alert reached one replica at a time and moved to another one whenever vmalert reconnected. The Alertmanager README asks for the opposite. It says "Do not load balance traffic between Prometheus and its Alertmanagers" and to point the sender at every instance, because the cluster deduplicates notifications only when each replica receives each alert.What this looked like on three clusters running 1.6.4, read through the Alertmanager API of each pod.
An alert that leaves a replica expires there and goes out as resolved, and the replica that receives it next sends it as a new firing notification. So a single long-running alert keeps producing firing and resolved notifications, and a receiver that rejects concurrent duplicates sees them as conflicts.
The change.
vm/vmalert.yamlrenders one notifier per Alertmanager pod,http://vmalertmanager-alertmanager-<i>.vmalertmanager-alertmanager.<namespace>.svc:9093. That is the address the operator builds for StatefulSet pods (VMAlertmanager.asPodFQDN), and the replicas already reach each other through the same per-pod names in their--cluster.peerarguments.monitoring.alertmanager.replicashelper, which now also setsspec.replicaCountof the VMAlertmanager. The notifier list cannot drift from the number of pods.Why not the operator's notifier selector.
VMAlertNotifierSpec.selectorexpands matched VMAlertmanagers into the same per-pod addresses, but only when the VMAlert is reconciled. The VMAlert controller does not watch VMAlertmanager objects, so a VMAlert reconciled before its VMAlertmanager exists, which can happen on a fresh install, would get no notifier until something else triggers a reconcile. A static list renders the same addresses without depending on that order.Upgrade impact. The VMAlertmanager is unchanged, it renders
replicaCount: 3as before. The VMAlert gets new notifier arguments, so the operator restarts the vmalert pod once.Testing.
helm unittestpasses for the monitoring chart, 24 suites and 304 tests. The new suitetests/vmalert_notifiers_test.yamlchecks the three notifier addresses, the replica count of the VMAlertmanager and the release namespace in the addresses.replicaCountthat no longer follows the helper.Screenshots
Not a UI change.
