Those with RTM/ESA experience may just like me have liked the ULOG display: it listed the user consuming most CPU (by default that was). If the system was slow, I displayed it to see who was since how long hogging the CPU.
With PERFKIT, such a report no longer exists. The good news is one can build something similar. As I found it so useful yesterday, I decided to share it here. Execute the following commands or include them in FCONX $PROFILE (PERFSVM 1CC by default): FC DEFLOG ULOG DESC User extremes (CPU, I/O, ...) FC DEFLOG ULOG H1 User extremes (CPU, I/O, ...) FC DEFLOG ULOG H2 ......... <-------system-------> <---User with......... FC DEFLOG ULOG COL 12 LEN 6 COPY SYSSUMLG LAST COL 12 NAME %CPU_ FC DEFLOG ULOG COL 18 LEN 7 COPY SYSSUMLG LAST COL 52 NAME IO/sec FC DEFLOG ULOG COL 26 LEN 7 COPY SYSSUMLG LAST COL 76 NAME Pag/sec FC DEFLOG ULOG COL 35 LEN 15 COPY CPU LINE 21 COL 65 NAME Max-%CPU FC DEFLOG ULOG COL 53 LEN 15 COPY CPU LINE 23 COL 65 NAME Max-IO/s FC DEFLOG ULOG COL 71 LEN 15 COPY CPU LINE 24 COL 65 NAME Max-PG/s And you we find a report like this in section "user defined data" USER EXTREMES (CPU, I/O, ...) ......... <-------SYSTEM-------> <---USER WITH.......... End Time %CPU_ IO/SEC PAG/SEC MAX-%CPU MAX-IO/S MAX-PG/S 15:21:00 16.2 42.7 .0 VSEPROD 10.8 SQLDSFP2 131 ........ ..... 15:22:00 23.4 109.6 .2 VSEPROD 18.2 VSEPROD 94.7 ........ ..... 15:23:00 38.7 145.4 .6 VSETEST 30.9 VSEPROD 239 ........ ..... 15:24:00 31.0 471.3 .1 PPRCMON 19.0 PPRCMON 649 ........ ..... 15:25:00 29.7 62.3 .1 VSEPROD 22.4 SQLDSFP2 155 ........ ..... (this system doesn't page, that explains the .... at the end) Note: the above statements are perfect for a z/VM 5.3, with 1 engine. If your system has more engines the "MAX" users are located farther down in de CPU report and you will need to change the LINE 21,23, and 24 accordingly.
