You can remove a worker node that is no longer working correctly from a vRealize Log Insight cluster. Do not remove worker nodes that are operating correctly from a cluster.

Warning: Removing a node results in data loss. If a node must be removed, ensure that it has been backed up first. Avoid removing nodes within 30 minutes of adding new nodes.

Prerequisites

Verify that you are logged in to the vRealize Log Insight web user interface as a Super Admin user, or a user associated with a role that has the relevant permissions. See Create and Modify Roles for more information. The URL format of the web user interface is https://log-insight-host, where log-insight-host is the IP address or host name of the vRealize Log Insight virtual appliance.

  2. Under Management, click Cluster.
  3. In the Workers table, find the node you want, click the pause icon,"" and click Continue.

    vRealize Log Insight removes the node from the cluster and sends out an email notification.
