The top of the topology pane displays a status message that logs the last updated timestamp, a summary of server status, and, if raised, a status change event message.
Sybase Central monitors the status of the multiplex and automatically refreshes the topology view and status message when servers are deleted or excluded. You can also specify a refresh interval.
