However kubernetes prohibits readinessprobe from being used because init containers cannot define readiness distinct from completion. Whilst a pod is running the kubelet is able to restart containers to handle some kind of faults.

With azure monitor for containers you can use the performance charts and health status to monitor the workload of kubernetes clusters hosted on azure kubernetes service aks azure stack or other environment from two perspectives.
