OMEGAMON XE has a client for Linux which is included in
the OMEGAMON XE for z/VM and Linux product, or can be purchased
separately. It includes process level data.

The CPU Timer based accounting is an improvement regardless of
whether you use normalization or not. The old method not only
had the potential for inflated values, but also was exposed to
skews in different directions. Normalizing the old values was a
clever way of dealing with the problem in the interim, but it
did not solve all the problems. Hence, the need for the CPU
timer approach. Thank you Martin. :-)

It is true that looking at both the VM and Linux data is
helpful. Two heads are better than one. Kevin, I believe you
have the VM part working already. There's been discussion
here about various VM based solutions for looking inside
the guest. For your needs, particularly in short term, a lot
of the Linux tools out there will work on z, and with the
new CPU timer are accurate. Stay away from things like TOP
that are noisy and just add overhead.

I should also mention that I don't see Performance Toolkit's
requirement to indicate which virtual machines you want
detailed data on for historic reasons as a hinderance to the
solution. Inconvenient perhaps, but not a show stopper. It
might be the confusion that in the old RTM product you could
only benchmark one virtual machine, where Performance Toolkit
allows you to benchmark any number. Also, I believe with
different uses of OMEGAMON XE you can set up historical
collection as well. Unfortunately I don't know the details.

I hope that helps.
