This article describes how to check the health of the services running in HDInsight on AKS cluster. It includes the collection of the services and the status of each service running in the cluster. You can drill down on each service to check instance level details.

There are two categories of services:

  • Main Services: Core services with respect to each cluster type.

  • Internal Services: Ancillary services, which help in the proper functioning of the cluster directly/indirectly.

Note

To view details in the Services tab, a user should be assigned Azure Kubernetes Service Cluster User Role and Azure Kubernetes Service RBAC Reader roles to an AKS cluster corresponding to the cluster pool. Go to Kubernetes services in the Azure portal and search for AKS cluster with your cluster pool name and then navigate to Access control (IAM) tab to assign the roles.

If you don't have permission to assign the roles, please contact your admin.

To check the service health,

  1. Sign in to Azure portal.

  2. In the Azure portal search bar, type "HDInsight on AKS cluster" and select "Azure HDInsight on AKS clusters" from the drop-down list.
