Monitor
For the Monitor function to be enabled, you must first mark the Collector you want to monitor in the SQL Collector window. To mark a Collector, simply click the row you want to monitor.
To start monitoring
Click 
Warning: If you have already monitored the Collector, re-monitoring erases your existing information.
If the start time of the Collector has not been reached, SQL Collector for Monitor Server will wait until it is time to begin. During and after monitoring, information acquired is updated in the SQL Collector window.
The SQL Collector window must remain open during the monitoring process. If you have started the monitoring process, but the scheduled time has not arrived, this window must remain open for the monitoring process to start and run to completion.
Monitor is terminated automatically once the end time is reached.
At the end of the monitoring process, duplicated SQL statements are eliminated. This may take a few minutes to complete.
Note: The ad-hoc monitoring from the right-click menu does not use the start, until, and duration time. The ad-hoc monitoring starts immediately and is only terminated by clicking Abort Monitor.
