Notes: The
idle loop count and time are used to calculate the multifunction IOP
utilization as follows:
- 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:
IOP utilization = (INTSEC - (MIIDLE * MIIDLT)/10**8) / INTSEC
- 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).
- The function 1 - 5 identifiers are for additional functions that
may be running in the primary IOP. Each function identifier has an
associated function time value. The function identifier may have the
following value:
