ZIIP is not reported as part of CPU. Chris Blaicher Technical Architect Syncsort, Inc.
-----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Brian Chapman Sent: Monday, February 25, 2019 1:53 PM To: [email protected] 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.
