Cluster Agent Validation

This page describes how to validate a Cluster Agent installation using the Kubernetes CLI or Helm chart.

Perform the following steps to validate that Cluster Agent is active.

  1. Verify that the Cluster Agent and Cluster Agent Operator pods are running by reviewing the status: 
    kubectl -n appdynamics get pods
NAME                                                           READY   STATUS    RESTARTS   AGE
appdynamics-operator-7958f676d9-gvdcw                          1/1     Running   0          4d21h
k8s-cluster-agent-5967c9b7b9-rkwzt                             1/1     Running   0          4d21h
  2. Verify that the Cluster Agent is reporting to the Controller. If the Cluster Agent successfully registers with the Controller based on the credentials you entered in the cluster-agent.yaml file, and the cluster-agent-secret you created in the appdynamics namespace (which contains the Controller Account Access Key), then the Cluster Agent displays in the Controller UI under Servers/Clusterusing the appName from cluster-agent.yaml
    Note: It may take 5-10 minutes for the data to populate.
  3. Verify the monitored namespaces. Under the cluster-agent Inventory dashboard, check that the monitored namespaces match the namespace configuration in the cluster-agent.yaml file and that the monitored namespaces contain deployed pods.

    If necessary, update the namespace configuration (nsToMonitorRegex) in the cluster-agent.yaml and re-create the Cluster Agent

    kubectl -n appdynamics delete -f cluster-agent.yaml
kubectl -n appdynamics create -f cluster-agent.yaml
