Create a Cluster Group

By default, Tenable Nessus assigns new nodes and agents to the default cluster group. You can create cluster groups that conform to your network topology. For example, you could create cluster groups for different regions of where your nodes and agents are physically located, which could minimize network traffic and control where your agents' connections occur.

A cluster group is different from an agent group, which is a group of agents that you designate to scan a target. You can use cluster groups to manage the nodes that agents link to within a cluster.

Note: If cluster child nodes have automatic software updates disabled, you must manually update them to Nessus 8.12 or later to use agent cluster groups. If cluster child nodes have automatic software updates enabled, nodes can take up to 24 hours to update. To ensure correct linking and configuration, wait for all child nodes to update to a supported Nessus version before configuring custom cluster groups. All child nodes must be on the same Nessus version and operating system.

Before you begin:

To create a cluster group:

  1. Log in to the Tenable Nessus Manager parent node.
