Don't have a citation, but I'm pretty sure the first value is for the box (sum of all LPARS) and the second is for this LPAR.
So, when the first value is 100% and the second is, say, 10%, then this LPAR is using 10% of the box while other LPARs are using the remaining 90% . When both are 100%, then this LPAR is consuming the whole box. When the LPAR is 100% but the CPU is anything less, then some sort of capping is active. For example, consider a 100 MSU box, a LPAR hard capped at 50 MSU, and no other LPARs. If LPAR would reported 100% busy then the CPU would report 50%. Same setup using 'soft capping' would show both at 100% for a while, then the LPAR would continue at 100% but the CPU would abruptly drop to 50% as the rolling four hour average exceeded 50 MSU. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of David Speake Sent: Tuesday, August 04, 2009 6:02 PM To: [email protected] Subject: SDSF DA fields CPU/L/Z/ SDSF DA displays a line of information above the 'COMMAND INPUT' line. SDSF DA SYSJ (ALL) PAG 0 CPU/L 68/ 34 LINE 1-1 (1) Can anyone point me to an IBM manual for citation as to exactly what CPU/L 68/ 34 in the above mean. The Help panel shows CPU/L/Z/ 26/ 26/ 0 | Percentage of time the CPU is busy, MVS, LPAR and zAAP views. The zAAP view would, I guess, reflect busy % for all CPUs (if any) designated as zAAP processors by PR/SM. But what is the definition/distinction for CPU/L (MVS/LPAR) views. I am looking at z/OS: Resource Measurement Facility Performance Management Guide, B.4.2 Value of LPAR CPU management and I cannot form a good definition. An explanation would be appreciated. A definition citation even more so. David NOTICE: This electronic mail message and any files transmitted with it are intended exclusively for the individual or entity to which it is addressed.
