Measure Reference Manual

STARTING-TIMER-CELLS
(ZMS Style only) Number of instrumentation timer cells in use at the start of the measurement interval.
Counter type: Snapshot.
STARTING-UCL
Number of user process code and library segment frames allocated in physical memory at the start
of the measurement interval. This counter includes the number of frames allocated for user process
TNS, accelerated, and native code segments for the short address spaces designated as user code
(UC) and user library (UL).
Counter type: Snapshot.
STARTING-UCME
Number of uncorrectable memory error (UCME) frames at the start of the measurement interval.
Counter type: Snapshot.
SVNET
ServerNet activity for the measured processor. This field is divided into these subfields:
Counter TypeDescriptionSubfield
IncrementingNumber of ServerNet transfers initiated in the measured
processor that brought information into the indicated
READ-REQUESTS
processor (CPU n). For transfers within the measured
processor, this count is the number of standard I/O read
requests. For transfers with other processors, the count
includes the number of DBIO read requests.
IncrementingNumber of ServerNet transfers initiated in the measured
processor that sent information out of the indicated
WRITE-REQUESTS
processor (CPU n). For transfers within the measured
processor, this count is the number of standard I/O write
requests and the number of message system send requests
initiated from the measured processor. For transfers to
other processors, the count includes the number of DBIO
write requests.
AccumulatingNumber of bytes transferred by read requests for the
indicated processor (CPU n).
READ-BYTES
AccumulatingNumber of bytes transferred by write requests for the
indicated processor (CPU n).
WRITE-BYTES
In Measure reports, ServerNet activity values are provided separately for each processor to or
from which the measured processor transferred data.
If you generate a report for all processors and use the TOTALS option, the report shows the total
ServerNet data transfer activity for each processor. The fields for each specific processor can be
interpreted as the total ServerNet data demand by that processor. I/O requests are counted once
in these totals, but message system interprocessor communication (IPC) requests are counted twice,
once in each processor involved in the transfer.
