Microsoft recently announced availability of Azure Monitor for containers for checking health and performance of Kubernetes clusters hosted on Azure Kubernetes Service (AKS). Major items to watch on that are:

 Multi-cluster View

Helps monitor all available clusters across subscriptions, resource groups and workspaces, and even helps you identify those clusters which are not yet monitored.

Drilldown in Performance Grid

From cluster view you can drill down to view performance details of your nodes, controllers and containers.

Live debugging

Review your container logs directly in Azure portal and allows pausing of live streams and search within logs for errors and issues.

Onboarding

Other than portal this monitor can be onboarded using Azure Resource Manager and CLI.
