Your CronJobs run on schedule, but Kubernetes won't alert you when they fail. Add heartbeat monitoring in one line of YAML.
Resource constraints, node affinity rules, or taints can prevent pods from scheduling. The job never starts.
Registry authentication expires, image tags change, or network issues block pulls. Job fails before code runs.
Memory limits exceeded, container killed mid-execution. No graceful error handling, no notification.
Deadlocks, network timeouts, or waiting on unavailable resources. The job never completes.
kubectl get cronjobs shows the schedule, not whether jobs actually succeed. You need external monitoring.
