Preparing Your Environment

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 vRealize^® 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.
