Enable Clustering

When you enable clustering on Tenable Nessus Manager it becomes a parent node. You can then link child nodes, each of which manages Tenable Nessus Agents. Once you enable clustering on a parent node, you cannot undo the action and turn Tenable Nessus Manager into a regular scanner or Tenable Nessus Agent manager.

Note: To enable Tenable Nessus Manager clustering in Tenable Nessus 8.5.x or 8.6.x, you must contact your Tenable representative. In Tenable Nessus Manager 8.7.x and later, you can enable clustering using the following procedure.

Note: All Tenable Nessus nodes in a cluster must be on the same version. Otherwise, the cluster deployment is unsupported.

To enable clustering in Tenable Nessus Manager:

  1. 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.

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

    The Cluster Setup page appears and displays the Settings tab.

  3. Select Enable Cluster.

    Caution: Once you enable clustering on a parent node, you cannot undo the action and turn Tenable Nessus Manager into a regular scanner or Tenable Nessus Agent manager.

  4. Click Save.

    Your Tenable Nessus Manager becomes a parent node of a cluster.

What to do next:

  • Link child nodes to the parent node.
  • Manage cluster groups.
