Information about CPU consumption in CTG per request inclusion in CH51 trace

We find a lack of information in the CPU consumption per request in CTG. We use CICS PA and there is no way of getting this information in any report. We have shown a similar interest in Req Id 21847.
But our requirement is:
We would like to know the CPU consumption of each flow in the CH51 trace, so maybe an interface to gather this information should be implemented.

    Capturing CPU usage from within a Java address space is not possible without incurring significant overhead - the mere act of attempting retrieve native platform information from the Java run time would in itself make this requirement unworkable in a production system, especially when you consider the multiple threads are involved in each request. At best, it might be possible for Gateway daemon statistics to obtain an overall CPU measurement at the address space level on z/OS. However, existing platform monitors such as the Tivoli OMEGAMON suite, or RMF are more than capable of providing this information already. The Java health center may provide an alternative tool for providing a Java-world view of activity within the Gateway daemon. 

    If a single connection factory is involved in a global transaction, then simply disable XA transaction support. This is now possible with the single JEE 6 compliant ECI resource adapter provided with CICS TG V8.1 or later.
