Finishing the thought, IBM's OMEGAMON comes to mind as well.  There's more
than one "decent" performance monitor Out There, so shop and compare.

Real point:  Successful z/VM+Linux deployments include, among other
things, tools that can monitor resource consumption of the box, your LPAR,
and your Linux guests.  But as has been noted, while that function is
necessary, it is not, by any reasonable measure, sufficient.  You must
also be able to correlate that with information on what's going on
*inside* the guest.

IMO, they should be part of POCs, too.
