5.6 Monitor settings

After entering the MONSET command (or selecting option E), we navigate to the

screen shown in Figure 5-12.

Figure 5-12 Monitor settings (option E or the MONSET command)

The Initial settings correspond to the monitor commands that were

uncommented from the PROFILE EXEC prior to invoking the PERFKIT

MODULE. They do not include the enabling of the USER EVENT that was

needed to display the system transaction statistics. As with system settings (the

SYSSET command), the monitor event scheduler must be enabled in order to

see the monitor settings changes in the bottom part of the display.
