CPU report

The CPU report provides you with an overview of the utilization of the individual processors.

Report output

The REPORT CPU statement is used to request the output of the CPU report.Overflow screens may be requested for this report.

Monitoring information

LM	Logical machine number.
Percentage of time during which the processor was in the following states:
TU %	user programs
TPR %	processing of program interrupts
SIH %	analysis of program interrupts
IDLE %	inactive
STOP %	Percentage of time during which the processor was not operable
NORMED TO 100 %	In the NORMED TO 100 % section, the sum of the percentage values for TU, TPR, SIH and IDLE is 100 %.
REAL	The percentage values measured for TU, TPR, SIH and IDLE are output in the REAL section. When using VM2000, there may be discrepancies between the NORMED value and the REAL value (see also section "SM2 together with VM2000"). In particular, you should remember that the times specified refer to the assigned CPUs of the VM and not to the system as a whole.
AVG	The average values across all processors are output in the AVG row.

While SM2 records the sum of the TU and TPR times precisely, this total is divided into TU and TPR times on the basis of the proportion of the samples that fall to TU and TPR. This causes statistical inaccuracies in the calculation of TU and TPR times, which can be noticeable in the case of small TU and TPR values (i.e. when a small number of samples fall to TU and TPR). TU or TPR values of 0.0 % (online reports) or 0.0 milliseconds (TIME_IO buffer of the C interface SM2GDAT), in particular, should therefore be interpreted with caution.

The connection between the CPU values under REAL and under CPU MEAS in the VM report is explained in section "Special applications".
