ZIIP is not reported as part of CPU.

Subject: CPU time and zIIP

Hello,

I'm trying to understand the CPU and ECPU times displayed on SDSF and the 
relation to zIIP processing time.

For example, here is a CICS region running a Java web service.

*CPU-Time ECPU-Time GCP-Time zIIP-Time zICP-Time zIIP-NTime*

*   164.42    166.28    90.89     30.21      3.42      71.29*

Here is a CICS transaction executing in the region to display various ASSB 
fields.

************ CPU DISPLAY *************

*ASCBEJST. . . . . . :      162.20*

*ASCBSRBT. . . . . . :        2.23*

*ASSBASST. . . . . . :         .00*

*ASSBPHTM. . . . . . :        1.86*

*CPU . . . . . . . . :      164.43 (ASCBEJST + ASCBSRBT + ASSBASST)*

*ECPU. . . . . . . . :      166.29 (ASCBEJST + ASCBSRBT + ASSBPHTM)*

*ASSB-TIME-ON-ZIIP . :       30.22*

*ASSB-ZIIP-ENCT. . . :        1.60*

*ASSB-ZIIP-PHTM. . . :        1.60*

*ASSB-ASST-TIME-ON-CP:         .00*

The CPU-Time, ECPU-Time, and zIIP-time match (as close as humanly possible to 
switch 3270 emulators and press enter). I was under the assumption that ECPU 
also included time spent on zIIPs, but that must not be true. Is zIIP time 
included in CPU and ECPU? I'm thinking it is not.


Thank you,

Brian Chapman
