Check the Health of a Load Balancer

Learn how to view the status of a load balancers associated with the instance's Kubernetes cluster manged by Oracle WebLogic Server for OKE.

1. Access the administration compute instance for your domain.
   See Access the Administration Instance.
2. Run the following command:

   kubectl get services --all-namespaces

   Output example:

   NAMESPACE                 NAME                                   TYPE           CLUSTER-IP      EXTERNAL-IP       PORT(S)                      AGE

   Make a note of the IP address of the services with type LoadBalancer and in the EXTERNAL-IP column.

3. Disconnect from the administration compute instance.
4. Sign in to the Oracle Cloud Infrastructure Console.
5. Click the navigation menu and select Networking > Load Balancers.
6. Select the Compartment that contains your stack.
7. Find the required load balancer by searching with the IP addresses that you noted in Step2.
8. Click the name of the load balance against the IP address you searched for.
9. Under Resources on the left, click Metrics.

   The Metrics tab displays a default set of charts for the selected load balancer.
