Processor Overview (PI_CPU)

Organization of this page

Function

The Processor Overview (PI_CPU) record stores performance data, taken at a specific interval, about the processors on the monitored host. This is a multi-instance record.

Notes

  • If the connection to the monitored host fails, the information cannot be collected.

  • If this record is collected in a Windows environment, 100 is set as the maximum value of the following fields whose ID (ID) field is _Total:

    • CPU % (CPU_PERCENT)

    • System % (SYSTEM_PERCENT)

    • User % (USER_PERCENT)

  • If the OS of both the PFM - RM host and the monitored host is 64-bit Windows, you can collect a maximum of 32 pieces of CPU information.

  • If the OS of the monitored host is AIX and a user other than the root user is collecting information, 0 is displayed in the following fields if that user does not belong to either the adm group or system group:

    • CPU % (CPU_PERCENT)

    • Idle % (IDLE_PERCENT)

    • System % (SYSTEM_PERCENT)

    • User % (USER_PERCENT)

    • Wait % (WAIT_PERCENT)

    • Ext1 (EXT1)

    • Ext2 (EXT2)

  • If the OS of the monitored host is the Workload Partition (WPAR) environment of AIX V6.1 or later, 0 is displayed in the following fields:

    • CPU % (CPU_PERCENT)

    • Idle % (IDLE_PERCENT)

    • System % (SYSTEM_PERCENT)

    • User % (USER_PERCENT)

    • Wait % (WAIT_PERCENT)

    • Ext1 (EXT1)

    • Ext2 (EXT2)

  • Information is not collected if TargetType is set to icmp in the monitoring target settings.

  • If the monitored host is running Solaris, and the CPU configuration is changed while PFM - RM for Platform is collecting performance information, PI_CPU records are not collected. Also, the following fields in PI records will have a value of zero:

    • Active CPUs

    • CPU %

    • Idle %

    • System %

    • User %

    • Wait %

    • Interrupt Counts/sec

    If this phenomenon occurs, the performance information will be revised to be correct at the next collection timing, so no measures need to be taken.

    Note:

    Changing the CPU configuration means that the following command was executed, resulting in a message such as <<pset created: n>> being output.

    Command: mpstat -p 5 2

Interrupt Counts/sec (INTERRUPT_COUNTS_PER_SEC)

Windows:

Rate at which the processor processed interrupt requests generated by hardware devices (for example, the system clock, mouse, disk drivers, data communication line, and NIC). DPC (delay procedure call) interrupts are not included. If this field increases greatly when there is no system activity, a hardware problem (e.g., a low-speed device) probably exists.
