Description of problem:
CNV 4.17.3 / OCP 4.17.10 and this alert is constant still... there are 397 of them firing in the last insights report:
cat ocp/5866595/b78eb09e-a2c0-4bdb-af29-5ae974612241/20250131160428-a4ee2e651a5d4667ac53881b968b3256/config/alerts.json | jq '.[] | select(.labels.alertname == "PodDisruptionBudgetAtLimit") | .labels.alertname' | wc -l
379
They are all from when the VMs were deployed on Jan 22 or 23:
{
"labels": {
"alertname": "PodDisruptionBudgetAtLimit",
"namespace": "vmtest",
"openshift_io_alert_source": "platform",
"poddisruptionbudget": "kubevirt-disruption-budget-b7mx4",
"prometheus": "openshift-monitoring/k8s",
"severity": "warning"
},
"annotations": {
"description": "The pod disruption budget is at the minimum disruptions allowed level. The number of current healthy pods is equal to the desired healthy pods.",
"runbook_url": "https://github.com/openshift/runbooks/blob/master/alerts/cluster-kube-controller-manager-operator/PodDisruptionBudgetAtLimit.md",
"summary": "The pod disruption budget is preventing further disruption to pods."
},
"endsAt": "2025-01-31T16:01:56.284Z",
"startsAt": "2025-01-23T16:21:26.284Z",
"updatedAt": "2025-01-31T15:57:56.345Z",
"status": {
"inhibitedBy": [],
"silencedBy": [],
"state": "active"
}
The operator is logging once per hour that the alert is already silenced:
./hco-operator-598f4b7cbc-d7lb4/hyperconverged-cluster-operator/hyperconverged-cluster-operator/logs/current.log:2025-01-22T16:43:34.664979676Z {"level":"info","ts":"2025-01-22T16:43:34Z","logger":"controller_observability","msg":"KubeVirt PodDisruptionBudgetAtLimit alerts are already silenced"}
It looks like it silenced the first alert and nothing after.
./hco-operator-598f4b7cbc-d7lb4/hyperconverged-cluster-operator/hyperconverged-cluster-operator/logs/previous.log:2025-01-13T18:21:26.255441563Z {"level":"info","ts":"2025-01-13T18:21:26Z","logger":"controller_observability","msg":"Silenced PodDisruptionBudgetAtLimit alerts"}
