This is as easy as "one two three" now with OMEGAMON XE on zOS V5.3. First from the LPAR overview screen in the Enhanced 3270UI pick your LPAR with MSU use high - in this example it is Z2 at 98% of MSU Capacity - put "M" in the selection for the 4HR Rolling Average MSU Statistics for Z2.
The "M" shows us the MSU details for the LPAR Z2.
Now Pick your 5 Minute time period of heavy MSU usage you want to see what workload is driving the MSU usage and lets pick 8:01 to 8:06 AM at 98.6% of MSU used. Put a "P" for CPU Utilization by address spaces for this interval. And we now see the address spaces using the CPU driving the 4HR Rolling average MSU use.
We see FLASHSCM, CICS3A2A and MQQ2S12S as the big users of CPU driving the MSU usage on Z2 to 98%. So it is as Easy as "one - two -three".
