I got an answer from IBM's z/OS Support, who found an old PMR with a
similar problem described. VM does not support CPMF (this is currently
not documented anywhere). Thus, RMF cannot provide accurate FICON channel
utilization data for any z/OS guest machine. To get valid FICON
utilization

Yes Bill I agree, there is a huge amount of data and additional steps are
needed to get meaningful results from it.
If you needed to get Data Set level access information and had no OEM

Thanks to everyone who has replied to my post. My research has gone in a
new direction the last few days.
During the holiday weekend, when system activity on both of our machines
was relatively low, I was able to compare the RMF channel utilization
values by running the same large

For one site, the RMF Channel Path Activity report is showing
substantially higher channel activity than for the other site. The times
of the high channel activity are well aligned with a testing schedule, but
I would like to further narrow down what is causing the extra activity.

We have two ESS-800s running at different sites. Each ESS is conncected
to a local z800 processor. Each device has access to four FICON channels.
Each device is using PAVs.
