How To Check The Health Status Of Your Cluster

Overview

This guide demonstrates different methods on how to check and review the health status of your Ondat cluster. Below are two of the common methods on how to assess the health status of a cluster:

  1. Through the Ondat SaaS Platform.
  2. Through the Ondat CLI

Prerequisites

  • If you are using the Ondat SaaS platform, ensure that your cluster has been successfully registered.
  • If you are using the Ondat CLI, ensure that you have successfully downloaded and configured the utility to communicate with your Ondat cluster.

Procedure

Option 1 - Check Cluster Health Status Through The Ondat SaaS Platform

  1. Login to the Ondat SaaS Platform and navigate to the Clusters tab » Click on View Details on the cluster that you would like to inspect further.

  2. In the Cluster Summary tab, information about the Connection Status is provided. To review the health status of the nodes in the cluster, click on the Nodes tab for more information.

Option 2 - Check Cluster Health Status Through The Ondat CLI

  1. Deploy and run the Ondat CLI utility as a deployment first, so that you can interact and manage Ondat through kubectl. Once deployed, obtain the Ondat CLI utility pod name for later reference.

    # Get the pod name of the Ondat CLI utility.
kubectl get pods --namespace storageos | grep "storageos-cli"

storageos-cli-578c4f4674-7jwrj                       1/1     Running   0          70s

  2. With the Ondat CLI now deployed, you can check the cluster health and nodes status:

    # Get the cluster-wide configuration and show the number of healthy nodes.
kubectl --namespace=storageos exec storageos-cli-578c4f4674-7jwrj -- storageos get cluster

# Get the number of nodes in your cluster and also show their health status.
kubectl --namespace=storageos exec storageos-cli-578c4f4674-7jwrj -- storageos get nodes
