Linux Diag

Does RedHat9 have a device exercise utility, like cstm in the HPUX world? I have a dual processor system that I am trying to push. I've been using seti to push the processors.

10x
RPM

I don't think there is anything specific but here is a web page that gives you loads of benchmarking tests you can download and try.

Or try this

while true
do
true
done

Robert,

The dd command is in most Linux distributions. The dd command from your HP-9000 server will with limited modifications allow you to do read testing under Linux.

I'll second that, depending on what you are looking for. dd wont output any stats at the end, but it sure will excercise your disks!
ex: dd if=/dev/mydisk of=/dev/null

A good CDROM and HDD exercizer is the `readcd' uty in the cdrtools package. It output can also be re-directed to /dev/null to heat up the inside of your computer case,particularly so during cold winter nights inside the server room. ;-)

If 'bonnie' is still around, it's an IO benchmarking tool. Good thrashing of IO.

As for Processor however, I'm really not sure.

The last big machine I tried testing (Quad PIII 800Mhz), I ended up running sowhere in the vicinity of 80 find/grep's doing bits and pieces before it would even use 50% of all of them.. Un-good. (Incidentally, RAID cache is a *MUST!* :P).

Bonnie can be found e.g. at

ftp://ftp.heise.de/pub/ix/benches/bonnie/

iX uses bonnie regular to benchmark various
systems.
