Hi, All.
I am trying to get the information about the system load averages
through the commands - uptime,vmstat,sar -q, even more TOP utility.
But, I don't know how much system load average is good for ?
Please, e-mail me.
Thanks.

Plus, it may not always give realistic "real world" performance
degredation figures, apart from the fact that "1" load average is
really number_of_processors on multiprocessor systems, I've had
perfectly acceptable responses on my system with loads of 300.

Hello,
I'm trying to monitor the usage of a machine. I know about process
accounting, which (as far as I understand) gives feedback about
per-user and per-processname usage. Can I get a feeling for "how
busy" the machine is from process accounting, or do I need to do this
some other way?
Naively, I would like to know things like the load average over time,
iowait statistics, and that sort of thing, but I am also looking for
suggestions on how to monitor this sort of thing on a longer
timescale. Any suggestions on either of these (admittedly ill
thought-out) questions?
