Drilling down into report windows

You should now be able to use the active report windows. To drill down into these windows,

move the cursor to any of the titles that are active (active titles display the number or letter in

white; inactive titles are in green). Some of the more useful report windows to drill down into

are:

21. User resource usage

22. User paging load

23. User wait states

28. User configuration

29. Linux systems

For example, to drill down into the Linux systems submenu window, enter the following

command:

Command ===> 29

Then type S over the in the row corresponding to the report you want to see.

14.3 Monitoring Linux

Measurements can show resource consumption of the Linux guest as measured and

dispatched by the VM host. It is also possible to measure performance data from within the

Linux guest itself.

To monitor Linux performance data at this level, a data gatherer process must be running

within each Linux guest you want to monitor. There are different ways of gathering this data.

Data can be gathered in the kernel and as a user application. Novell SUSE SLES9, SLES10
