Opsview - Remove a collector cluster

This article describes how to completely remove a collector cluster, including all collectors within the cluster.

Prerequisites

First, you must either delete the hosts monitored by the cluster or move them to be monitored by other clusters. The following articles may help:

• Identify hosts monitored by a collector cluster
• Move all hosts monitored by a cluster to another cluster

The cluster being deleted cannot have any monitored hosts assigned to it, except hosts that are collectors within the cluster,

Process

1. Log in to the UI as an administrator and navigate to Configuration > Monitoring Collectors then switch to the Clusters tab.
2. Click the contextual menu of the cluster to be deleted, then click Edit.
3. Click to untick the Activated box.
4. Click Submit Changes.
5. Click the contextual menu of the cluster to be deleted, then click Delete.
6. Click OK to confirm the cluster deletion.
7. Switch to the Collectors tab.
8. Delete each collector that was in the cluster by clicking its contextual menu then clicking Delete. These clusters will have no entry in the Monitoring Cluster column.

10. Update your deploy files to remove any configuration related to the deleted cluster and its deleted collectors. You must update opsview_deploy.yml and may also need to update user_vars.yml.
