Hi,
Made some tests. Perftk shows the mixed processor types for a "Type VM" 
Lpar, on some screens. Like FCX100 and FCX144.
But I can't find any field "by processor" to use in the PLOT screens. At 
least none in the menu... 
Regards,

Perfkit: plotting IFL and classic processors in 2 graphs
Sent by:

I've got a customer for which we are planning to merge its 2 LPARS into 
one ZVM-type LPAR.

He has a z10 with 2 processors: a classic and an IFL.  At the installation 
time z/VM 5.3 was the most recent VM, so they created two LPARs: one LPAR 
with "classic" processors for his VM/VSE workload, and an IFL LPAR with 
Linuxes.

With the installation of z/VM 5.4, it is possible to merge both and 
simplify system management (like only 1 tape drive available, so the IFL 
things to backup have to be done by the other LPAR), etc...

My customer has a valid question: how will he be able to use PERFKIT's 
browser interface to plot the %CPU of the IFL and of the classic 
processor.  It is indeed possible that the load for the IFL's becomes too 
high, but the classic processor has "room".  A plot with the combined load 
would hide the bottleneck.

The manual and the browser interface doesn't make it clear it one can plot 
CPU used by processor (or by processor type).
