Predefined PrometheusRules

This page lists the PrometheusRules that KubeStack+ ships out of the box. You can route their alerts to your channels — there is no need to write the rules yourself.

How it works

The rules below are deployed and evaluated by the platform's Mimir ruler against every workload on the cluster. When one fires, the alert is routed through the same Alertmanager that handles your custom alerts — your AlertmanagerConfig (see Configure application alerting) picks them up automatically based on namespace.

What you get

Kubernetes apps

Name	Description
KubePodCrashLooping	Pod Namespace/Pod is restarting N times / 5 minutes.
KubePodNotReady	Pod Namespace/Pod has been in a non-ready state for longer than 15 minutes
KubeDeploymentGenerationMismatch	Deployment generation for Namespace/Deployment does not match, this indicates that the Deployment has failed but has not been rolled back.
KubeDeploymentReplicasMismatch	Deployment Namespace/Deployment has not matched the expected number of replicas for longer than 15 minutes.
KubeStatefulSetReplicasMismatch	StatefulSet Namespace/StatefulSet has not matched the expected number of replicas for longer than 15 minutes
KubeStatefulSetGenerationMismatch	StatefulSet generation for Namespace/StatefulSet does not match, this indicates that the StatefulSet has failed but has not been rolled back.
KubeStatefulSetUpdateNotRolledOut	StatefulSet Namespace/StatefulSet update has not been rolled out.
KubeDaemonsetRolloutStuck	Daemonset Namespace/Daemonset has not finished or progressed for at least 15 minutes.
KubeContainerWaiting	Pod Namespace/Pod container Container has been in waiting state for longer than 1 hour.
KubeDaemonsetNotScheduled	Pods of Daemonset Namespace/Daemonset are not scheduled.
KubeJobCompletion	Job Namespace/Job is taking more than 12 hours to complete.
KubeJobFailed	Job Namespace/Job failed to complete. Removing failed job after investigation should clear this alert.
KubeHpaReplicasMismatch	HPA (Horizontal Pod Autoscaler) Namespace/HPA has not matched the desired number of replicas for longer than 15 minutes.
KubeHpaMaxedOut	HPA (Horizontal Pod Autoscaler) Namespace/HPA has been running at max replicas for longer than 15 minutes.

Kubernetes storage

Name	Description
KubePersistentVolumeFillingUp	The PersistentVolume claimed by PersistentVolume in Namespace Namespace is only Percentage % free.
KubePersistentVolumeErrors	The persistent volume PersistentVolume has status Failed/Pending.
