Move an Agent to a Cluster Group

By default, Tenable Nessus assigns new agents to the default cluster group. You can manually add agents to a different cluster group; for example, you could add agents that are in a similar location to the same cluster group. An agent can only belong to one cluster group at a time.

When you move an agent to a cluster group, the agent relinks to an available node in the cluster group. There may be a mismatch in the number of agents listed for the cluster group and actual usage when an agent is moving or relinking.

Before you begin:

• Ensure you have added at least one child node to the cluster, as described in Link a Node.
• Ensure the cluster group you want to add an agent to has at least one node, as described in Add a Node to a Cluster Group.

To move an agent to a different cluster group:

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

2. In the top navigation bar, click Sensors.

   The Linked Agents page appears. By default, Linked Agents is selected in the left navigation menu and the Linked Agents tab is active.

3. In the left navigation bar, click Agent Clustering.

   The Cluster Groups page appears.

4. In the cluster groups table, click the row of the cluster group that contains the agent you want to move.

   The cluster group details page appears and shows the Cluster Nodes tab by default.

5. Click the Agents tab.

   The agents assigned to the cluster group appear in a table.

6. In the agents table, select the check box for each agent that you want to move to a different cluster group.

7. In the upper-right corner, click Move.

   The Move Agent window appears.

8. In the drop-down box, select the cluster group to which you want to move the agent.

   Note: Agents can only belong to one cluster group at a time. If you move the agent to a different group, it relinks to an available node in the new cluster group.

9. Click Move.

   Tenable Nessus Manager moves the agent to the cluster group.
