Failed Kubernetes Job alerts

A Job runs work until it succeeds or reaches its failure condition. kwatch watches Jobs that fail or become suspended, helping the team distinguish a workload error from an intentional pause.

What kwatch detects

Setting	Default	Purpose
jobMonitor.enabled	true	Watch failed or suspended Jobs.

An intentional suspension may not require action. Check who changed the Job and whether the pause is part of a planned operation before responding.

Investigate a failed Job

kubectl describe job <name> -n <namespace>
kubectl get pods -n <namespace>

Look at Job conditions and the Pods it created. Inspect the failing Pod's Events and logs to understand whether the problem is in the task, its image, configuration, or a cluster dependency. If the Job is suspended, confirm the expected schedule and owner.

Configure the monitor

Use the interactive manager to change settings. The equivalent configuration fragment is:

jobMonitor:
  enabled: true

Run kwatch lint after a change. For recurring work, see the CronJob monitor.
