Scratchpad is the “Design Mode of the Health Monitor”. Through Scratchpad you can design and configure:
Collector Managers
Collectors
Event Sources
Connectors
Event Source Servers
You can right-click the Sentinel icon and add the components. For more information, see Section 10.4.2, Adding Components to Event Source Hierarchy.
NOTE:You cannot view the status of any object in the design mode as they are not connected to an instance of a real Collector Manager.
