Configure the Kubernetes adapter to monitor clusters created on Red Hat OpenShift. You have to create one Kubernetes adapter for each Guest Cluster that you want to monitor.
Prerequisites
-
Verify that you have installed VMware Aria Operations Management Pack for Kubernetes.
- Verify that the control plane of the Management Cluster is accessible and resolvable.
-
Select either the cAdvisor or Prometheus monitoring option.
- If you want to use Prometheus, ensure you have the server running and the endpoint is accessible with the credentials.
- The Prometheus server packaged with Red Hat OpenShift is accessible only with token based auth. If you want to use this Prometheus instance, ensure you have a proxy set up in front of the Prometheus server.
-
Note:
-
You can create user-defined custom roles but it should have the read-only access to all the resources in the cluster and the Kubernetes API.
- Only a few performance metrics are collected using cAdvisor collector service for certain container runtimes.
