Measure Reference Manual

CPU-QTIME
Time (in microseconds) that processes spent on the ready list. In PVUs earlier than Measure G05,
the ready list includes processes waiting on page faults. The CPU MEM-QTIME counter shows the
time spent waiting for arrival of message system data.
In Measure G05 and later PVUs, a process no longer remains active in the ready list timer, so the
value of MEM-QTIME is zero.
Counter type: Queue.
DISC-IOS
Number of I/O disk transfers performed by disk processes in the measured CPU. This count includes
direct bulk I/O requests initiated by this CPU for other CPUs.
In D-series and G-series RVUs, this is a 32-bit counter. In H-series and J-series RVUs, this is a 64-bit
counter.
In G-series RVUs, the DISC-IOS-F field is a 64-bit version of DISC-IOS.
Counter type: Incrementing.
DISPATCHES
Number of times a process was selected from the ready list and executed by the CPU. The
DISPATCHES counter for the PROCESS entity shows the number of times a particular process was
dispatched (selected and run).
Counter type: Incrementing.
ENDING-FREE-CIDS
Number of counter ID control blocks available for new counter records in this processor at the end
of the reported measurement interval.
Counter type: Snapshot.
ENDING-FREE-MEM
Number of free memory frames at the end of the measurement interval.
Counter type: Snapshot.
ENDING-SCL
Number of system process code and library segment frames allocated in physical memory at the
end of the measurement interval.
Counter type: Snapshot.
ENDING-TIMER-CELLS
(ZMS Style only) Number of instrumentation timer cells in use at the end of the measurement interval.
Counter type: Snapshot.
ENDING-UCL
Number of user process code segment frames and library segment frames allocated in physical
memory at the end of the measurement interval.
Counter type: Snapshot.
ENDING-UCME
Number of uncorrectable memory error (UCME) frames at the end of the measurement interval.
Counter type: Snapshot.
