If you want a report, you should check out the sar command; using it will show you a report similar to
this:
smp smp 4.0 2 PENTIUM 09/17/98
00:00:00 %usr %sys %wio %idle
07:00:00 0 0 3 97
08:00:00 0 1 4 95
08:10:00 1 2 9 87
08:20:00 2 4 11 83
08:30:00 3 5 57 35
08:40:00 2 5 23 69
08:45:00 3 6 61 30
Notice how the situation starts to get really ugly at 8:20 (when everyone’s had their coffee and is now
tearing into things)? At 8:30, the system is only 35 percent idle, as opposed to 97 percent idle at 7:00. As
you can see, the sar command can help you with long-term monitoring. Both sar and vmstat have
manual pages that you can access online by typing this:
man
NetWare
If you’re a NetWare user, unfortunately, you have no long-term resource monitoring solution provided by
Novell, although third-party solutions are available. You can, however, use the NetWare monitor screen
to check out various resources. Simply type
load monitor
at your console prompt, and you’ll see the processor utilization on the front page. Go to the Processor,
Memory, or Resource Utilization submenus for more details.
