Through the Admin Console you can only delete the node agent configuration from the domain. You cannot delete the actual node agent. To delete the node agent itself, run the asadmin command delete-node-agent on the node agent’s local machine. For more information, see Deleting a Node Agent.
Before deleting the node agent configuration, the node agent must be stopped and it must not have any associated instances. To stop a node agent, use the asadmin command stop-node-agent. See Stopping a Node Agent for more information.
In the tree component, select the Node Agents node.
On the Node Agents page, select the checkbox next to the node agent to be deleted.
