INTNUMInterval number: The nth sample database interval based on the start time specified in the Create Performance Data (CRTPFRDTA) command.PD (5,0)DTETIMInterval date (yymmdd) and time (hhmmss): The date and time of the sample interval.C (12)INTSECElapsed interval seconds: The number of seconds since the last sample interval.PD (7,0)IOPRNIOP resource name.C(10)LIIOPReservedC (1)LITYPEIOP type.C (4)LIRIDCResource ID of controller: Field cannot be displayed.C (8)LITPKTTotal packets transferred.PD (11,0)LIKBYOTotal KB transmitted from the IOP to the system across the bus.PD (11,0)LIKBYITotal KB transmitted to the IOP from the system across the bus.PD (11,0)LIOPSROPSTART bus unit message received from another bus unit using normal flow.PD (11,0)LIOPSSOPSTART bus unit message received from another bus unit using reverse flow method 2.PD (11,0)LISGLRSignal bus unit message received from another bus unit.PD (11,0)LIOPSTOPSTARTS sent to another bus unit using reverse flow method 2.PD (11,0)LISGLSSignals sent to another bus unit.PD (11,0)LIRSTQRestart queues bus unit message sent to another bus unit.PD (11,0)LIRQDODMA requests sent for output of data: The number of requests the IOP sends to the system for data to be sent from the IOP to the system across the bus.PD (11,0)LIRQDIDMA requests sent for input of data: The number of requests the IOP sends to the system for data to be sent to the IOP from the system across the bus.PD (11,0)LIBNAROccurrences of BNA received.PD (11,0)LIIOQCWait-on-I/O queue count: The number of I/O requests on the wait-on-I/O queue at sample time. The wait-on-I/O queue holds I/O requests that are being processed or waiting to be processed.PD (11,0)LISQCSuspend queue count: The number of elements on the suspend queue at sample time.PD (11,0)LIAQCActive queue count: The number of elements on the active queue at sample time. The active queue holds I/O requests that were sent from the host system and were not yet sent to the wait-on-I/O queue.PD (11,0)LITWIUTwinaxial use count: The number of times when the wait-on-I/O queue was sampled and the count was not zero (I/O in progress). If this value is divided by the sample count, the result (times 100) is the percentage of time when I/O is occurring.PD (5,0)LISMPLSample count: The number of times during the snapshot interval that the various IOP queues were sampled.PD (5,0)LIIDLCIdle counts (see notes): The number of times the workstation IOP ran an idle loop. This is done when the IOP has no work to perform. This count is used with the idle loop time.PD (11,0)LIIDLTIdle loop time (times 0.01 microsecond) (see notes): The time (in hundredths of microseconds) to run the idle loop once.PD (11,0)
