Hi all
Below is our three CF reports at the same time.
Report 1. CFSYS from RMF MONIII
The Coupling Facility Systems (CF Systems) report (CFSYS) gives you information
about the distribution of coupling facility requests
among the systems and about the activities in the subchannels and paths
attached to the coupling facilities in the sysplex

Our question: 1 Why these three report is difference for Subchannel Delay?
2 Why The Subchannel Delay is just 0.1% in CFSYS ?
Thanks a lot!Best Regards,
