Example
To display I/O interrupt activity, type
PIO
AMTO70I I/O Interrupt data being gathered for 15 seconds
AMTO73I Processor I/O Interrupt Activity Report
[1] [2] [3]
AMTO74I CPU 00 processed 676 interrupts ( 0% were through TPI)
AMTO74I CPU 10 processed 1,116 interrupts ( 1% were through TPI)
AMTO73I Processor I/O Interrupt Activity Report
[1] [2] [3]
AMTO74I CPU 00 processed 676 interrupts ( 0% were through TPI)
AMTO74I CPU 10 processed 1,116 interrupts ( 1% were through TPI)
Legend:
- CPU identifier (CPUID) for the processor whose activity is being reported
- total number of I/O interrupts (including TPIs) processed by this CPU in the interval
- percentage of I/O interrupts processed by this CPU through the Test Pending Interrupt (TPI) instruction--the percentage of I/O interrupts that do not require a physical program status word (PSW) swap.
