That has been my experience since going to a z10 as well, PERFKIT just shows "Total CPU" which is the sum of your CP engines + IFL's. I also would like to be able to segregate them by processor type (i.e. I don't care if my IFL's are running at 100%, it means my Linux guys are "doing stuff" - but I DO care when my CP runs at 100% for an extended period of time since that would be abnormal in this shop).

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...

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). -- Kris Buelens, IBM Belgium, VM customer support
