Queue Lengths

This Enform session displays the PROCESS CPU-BUSY-TIME counter in
microseconds in the column CPU-BUSY-TIME and as a percent busy value in the
column PERCENT BUSY:

>OPEN PROCESS;
>LIST PROGRAM-FILE-NAME, CPU-BUSY-TIME,
>((CPU-BUSY-TIME*100.000)/DELTA-TIME) HEADING "PERCENT BUSY",
>WHERE PROGRAM-FILE-NAME CONTAINS "MCOM";

$DATD QUOTAS MCOM 382553 .452

The PROGRAM-FILE-NAME field of the PROCESS record contains the name of the
executing program file. The DELTA-TIME field contains the duration of the report
window in microseconds. The WHERE clause of the LIST command selects the
records to be included in the report.

Queue Lengths

The uninterpreted value provided by the structured report for a queue counter is the
number of microseconds spent in the queue. To calculate average queue length, use
this formula:

(counter * 1.000)

delta-time

This Enform session displays the PROCESS PRES-PAGES-QTIME counter in
microseconds in the column PRES-PAGES-QTIME and as an average queue length in
the column AVG LENGTH:

>LIST PROGRAM-FILE-NAME,PRES-PAGES-QTIME,
>((PRES-PAGES-QTIME*1.000)/DELTA-TIME) HEADING "AVG LENGTH",
>WHERE PROGRAM-FILE-NAME CONTAINS "MCOM";
