Add a Node to a Cluster Group
By default, Nessus assigns new linked nodes to the default cluster group. You can also add a node to a different cluster group manually; for example, you could add nodes that are in a similar location to the same cluster group. A node can only belong to one cluster group at a time.
When you move a node that belonged to another cluster group, any agents that were linked to that node remain in their original cluster group and relink to another node in the original cluster group.
Note: If cluster child nodes have automatic software updates disabled, you must manually update them to Nessus 8.12 in order 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 Nessus 8.12 prior to configuring custom cluster groups.
Before you begin:
- Ensure you have added at least one child node to the cluster, as described in Link a Node.
- If you want to add a node to a cluster group other than the default cluster group, first Create a Cluster Group.
To add a child node to a cluster group:
Log in to the Nessus Manager parent node.
In the left navigation bar, click Agent Clustering.
The Cluster Groups page appears.
In the cluster groups table, click the row of the cluster group to which you want to add a node.
The cluster group details page appears and shows the Cluster Nodes tab by default.
In the upper-right corner, click Add Nodes.
The Add Nodes window appears and shows the available nodes.
- (Optional) Search for a node by name to filter the results.
In the nodes table, select the check box next to each node you want to add.
Note: A node can only belong to one cluster group at a time. When you move a node that belonged to another cluster group, any agents that were linked to that node remain in their original cluster group and relink to another node in the original cluster group.
- Click Add.
Nessus Manager moves the node to the cluster group.
