SM2 reports

(VM)

This abbreviation will be output in the first line if the system
monitored is a VM2000 system.

(2 LM’S)

This additional information indicates how many logical machines
were active.

Proportion of CPU time during which the CPU was in the following processor states:

TU

User programs

TPR

Processing of program interrupts

SIH

Analysis of program interrupts

IDLE

Inactive

For systems comprising a number of logical machines, mean values
for all active logical machines are output.

The sum of the TU, TPR, SIH and IDLE times is always 100%. For
evaluation of the TU and TPR percentages, see section “Accuracy
of the SM2 data” on page 343ff.

In the monitoring cycle in which reconfiguration took place, these
values and the number of I/O operations are marked as invalid (*).

SM2 supplies a STOP time for each logical machine. This value
indicates the proportion of time during which the relevant logical
machine was inoperable.

The STOP time is output in the SM2 report CPU and by SM2R1 in
the *CPU report group when the parameter PROCESSOR-
SPLITTING=*YES is specified.

/390

This value is supplied only on SR2000 machines. It indicates the
relative proportion of TU that has elapsed in /390 mode.

The monitored data on CPU utilization and on service units is based on native CPU time
(see “CPU time and CPU service units on SR2000” on page 446 of the glossary).
