Add an Agent to a Cluster Group

By default, Tenable Nessus assigns new agents to the default cluster group. You can also add agents to a different cluster group manually; 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 add an agent to a cluster group, the agent relinks to an available node in the cluster group.

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 add an agent to a cluster group:

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

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

   The Cluster Groups page appears.

3. In the cluster groups table, click the row of the cluster group to which you want to add an agent.

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

4. Click the Agents tab.

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

5. In the upper-right corner, click Add Agents.

   The Add Agents window appears and shows available agents.

6. (Optional) Search for an agent by name to filter the results.

7. In the agents table, select the check box next to each agent you want to add.

   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.

8. Click Add.

   Tenable Nessus Manager adds the agent to the cluster group.
