Measure Reference Manual

Counter type: Sampling.
NATIVE-BUSY-SAMPLES
(ZMS Style only) Number of times the sampling operation found the measured code executing
native code.
Counter type: Sampling.
PROCESS-BUSY-SAMPLES
Number of times the sampling operation found the process executing.
Counter type: Sampling.
TNS-BUSY-SAMPLES
Number of times the sampling operation found the measured code executing TNS code. This
counter applies only to measurements taken on a TNS/R or TNS/E system. ACCEL-BUSY-SAMPLES
+ TNS-BUSY-SAMPLES = CODE-RANGE-BUSY-SAMPLES.
Counter type: Sampling.
Legacy Style Only Counter Field DDL Definition for PROCESSH Entities
This counter field is used in Legacy Style DDL records only.
TNSR-BUSY-SAMPLES
(Legacy Style only) Number of times the sampling operation found the measured code executing
TNS/R native code. This counter applies only to measurements taken on a TNS/R system.
TNSR-BUSY-SAMPLES = CODE-RANGE-BUSY-SAMPLES.
Counter type: Sampling.
Usage Notes for H-Series and J-Series PROCESSH Entities
• In H-series and J-series RVUs, the ALLINTR option for PROCESSH sampling is disabled. On
systems running H-series and J-series RVUs, all interrupt handlers are individual and separate
Interrupt/Auxiliary Processes and so can be sampled and measured individually. No error is
returned if an ALLINTR PROCESSH measurement is configured, but no records will be returned.
Interrupt/Auxiliary processes can be identified through the value of their priority in their
PROCESS records. Only these processes have a PRI value of 255. So a MEASCOM command
of LIST PROCESS 0,*, IF PRI = 255 returns a list of all Interrupt/Auxiliary processes that are
executing on processor 0, provided that the measurement was done on all processes. The
information (program file name, pin, and so on) from these records can be used to configure
a PROCESSH measurement on these items if needed.
• In H-series and J-series RVUs, the PROCESSH sampling rate is increased to approximately
500 samples per second. The sampling rate is per IPU for J-series RVUs. This sampling rate
is not fixed. If more samples are needed within a shorter duration, the rate can be increased.
However, because this might negatively affect the performance of the other processes, use
this facility only when necessary. To increase the PROCESSH sampling rate, before issuing
the START MEASSUBSYS command, add this DEFINE statement to the TACL session context.
The file name specified determines the scaling factor of the sampling rate:
