Hi All,
I just install Ubuntu 6.06 lts. With the box up and running it appears that there is disk activity because the light on the case is active. However running top shows the box is basically idle (CPU < 1%) and "ps aux" shows nothing unusual. I do not claim to be a sys admin however so I may not be interpreting things correctly. The fans seem to be working harder than before as well.
What command line tools should I be looking at determine the health of the machine and drives. The os is on an IDE drive and I have a raid (MegaRAID) for the other drive.
I know this is a bit vague but I am not sure where to start. I have been using opensuse but now I do not have x or the other tools that come bundled with kde.
Thanks, Mike
HI Mike,
Here's what I would try:
a) Are you sure that the disk activity light on the case is properly wired to your MB? Is the light constantly on, or does it flicker?
b) unplug the network cable to insure that the disk activity isn't caused by something on the network
c) If you are sufficiently patient and wait, does the activity stop (say in 5-10 minute)?
d) What happens if you run "tail -f /var/log/messages" as root ? Lots of messages here could cause disk activity.
I'm sure other folks with have other ideas, but that's my 2cents, devalued for inflation.
HTH,
Andy

Thanks, I am now able to find both on www.freshmeat.net. Gentoo linux has an ebuild for the sysstat package that includes the sar command. Thanks for the help. On Sat, 15 Sep 2007 07:50:09 -0700 (PDT), "Mike Leo" <mleo963@yahoo.com> said:

on Debian/Ubuntu systems, sar is an alternative provided by either the sysstat or atsar package. The command line options, and formatted output are NOT the same, so any scripts won't easily port from one to the other. In my experience, people are generally referring to the version included in 'sysstat' -- Aaron Haviland
