|
|
count and time are used to calculate the communications IOP utilization as
|
|
follows:<ol><li>Convert the product of the idle loop count times the idle loop time from
|
|
hundredths of microseconds to seconds. Subtract this from the interval time,
|
|
and divide the results by the interval time. For example: <blockquote>IOP utilization
|

= (INTSEC - (CIIDLC * CIIDLT)/10**8) / INTSEC</blockquote>

</li>
|
|
<li>The performance monitor reports I/O processor (IOP) statistics different
|
|
beginning with Version 3 Release 7. Therefore, performance statistics for
|
|
IOPs introduced in Version 3 Release 7 or later releases are reported in the
|
|
QAPMMIOP file. Performance statistics are reported in the QAPMMIOP file even
|
|
if the IOP supports only one of the three IOP functions (communications, disk,
|
|
or local workstation). Performance statistics for IOPs that were introduced
|
|
before Version 3 Release 7 will continue to be reported in the appropriate
|
|
IOP file (QAPMCIOP, QAPMDIOP, QAPMLIOP, and QAPMMIOP).</li>
