18.9. Changing the Agent's Availability Scan Period
Since availability is processed on the server, large environments with hundreds of agents and tens of thousands of resources can stress the server and hurt performance. In that case, the default scan interval may be too short, and setting a longer scan interval may improve JBoss ON server performance.
Note
When changing core agent or server settings, especially ones that impact JBoss ON performance, contact Red Hat Support Services for assistance.
