CIF1ID Subfunction 1 ID: The identifier for addition functions that may be running in the primary IOP processor. C (2)
CIF1TM Subfunction 1 time: The total processing unit time (in milliseconds) used by the IOP function that is running in the primary IOP processor. PD (11,0)
CICPU2 Processor time in milliseconds for the second IO processor, which handles specialized functions. This field applies to Integrated xSeries® Servers (excluding I/O adapter versions) and wireless IOPs. This field is zero for other IOPs. Collection Services will not report values for Integrated xSeries Servers. PD (11,0)
Note:

The idle loop count and time are used to calculate the communications IOP utilization as follows:

  1. 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 - (CIIDLC * CIIDLT)/10**8) / INTSEC
  2. 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).
  3. The function 1 identifier is 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:
Value Description
00 No time value supplied
11 Integrated xSeries Server pipe task (Integrated xSeries Server was previously known as file server I/O processor and FSIOP)
42 Localtalk task
43 Wireless task
