KubeDeploymentReplicasMismatch

This means that deployment has not matched the expected number of replicas for longer than an hour. It can be caused by different triggers.

Troubleshooting

• Check the pod logs
• kubectl describe pod and look at the events
• when the namespace is monitoring-stack-corp-xxx, the component is Thanos. After troubleshooting, if you decided to reinstall one of the Thanos components, use the following documentation to do it.

Note

When the namespace is monitoring-stack-corp-xxx, notice that deployment=thanos-query means that the problem appears on the Querier dedicated to the Ruler.
