EXTSUM
The EXTSUM control statement causes the CMF MONITOR Extractor to sample data on CPU and channel busy status, paging, I/O activity, TSO transaction rate, workload status, and service allocation percentages.

Monitoring modes | An EXTSUM statement can be specified for CPM mode only; this statement is not valid for IPM mode. | |
Sampler and record types | The EXTSUM statement controls the EXTS sampler, which produces CMF type 240-06 and 240-07 user records. | |
Analyzer statements and reports | PERFSUM, PERFORM | Performance Summary Report |
The Extractor Summary Report is produced only if the SPINOFF parameter is defined with a valid SYSOUT class in the EXTSUM statement. The SPINOFF parameter causes the CMF MONITOR Extractor to dynamically allocate a JES spin-off data set at the end of each recording interval, without disrupting the continuous sampling functions of the CMF MONITOR Extractor. From this spin-off data, the CMF MONITOR Extractor automatically produces the Extractor Summary Report for every recording interval and sends it to the specified SYSOUT. However, the other parameters and the WORKLOAD control statement also affect the Extractor Summary Report. If JES=NO is defined in the EXTSUM statement, the Job Class Activity section of the Extractor Summary Report is not produced. | ||
Other BMC Software products | The CACHE control statement must be defined in the Extractor JCL for MainView for z/OS. | |
Parameters
The parameters for the EXTSUM control statement are:
JOBCLASS= | specifies the job class queues to be monitored for activity and a description for each class to be reported in the Extractor Summary Report You can specify a maximum of 36 classes and descriptions. Any class that is specified is reported separately on the Extractor Summary Report; all other classes are grouped together and described as OTHER. There are two values to define to the JOBCLASS parameter:
|
|---|---|
SRVCLASS= | specifies the service classes and periods to be monitored for the Extractor Summary Report and the Performance Summary Report A maximum of 64 service classes can be specified. There are two values to define to the SRVCLASS parameter:
|
JES= | specifies whether the job entry subsystem is to be sampled and controls whether the Job Class Activity section of the Extractor Summary Report is produced The default is JES=NO. For the Job Class Activity section of the Extractor Summary Report to be produced, this value must be defined as JES=YES, and the SPINOFF parameter must be defined with a valid SYSOUT class. For JES2 sampling, code JES=YES. For JES3 sampling, code JES=YES and make sure that the procedure for JES3INIT was assembled and linked during AutoCustomization or manual customization. If you have upgraded your JES3 release since you installed CMF MONITOR, you must reassemble the JES3INIT procedure to link to the new offsets. Use AutoCustomization or the instructions in the hilevel.BBILIB member @@YCH300 to reassemble the JES3INIT procedure. |
COPIES= | specifies the number of copies of the Extractor Summary Report to be printed You can specify up to 99 copies. The default is 1. This parameter is meaningful only if the SPINOFF parameter is defined with a valid SYSOUT class. |
SAMPLE= | specifies the number of milliseconds between data gathering cycles The default is 1000. The sample rate cannot be below 500 or over 9999. |
SPINOFF= | specifies the SYSOUT class to be dynamically allocated for printing the Extractor Summary Report You can specify any valid SYSOUT class. The default is A. The SPINOFF=NO parameter eliminates all spin-off reports but allows Extractor summary records (CMF type 240-06 user records) to be written and later summarized by the Analyzer. |
