CFDATA
The CFDATA control statement causes the CMF MONITOR Extractor to collect data for all coupling facilities to which the system is connected, and write one SMF type 74-4 record for each coupling facility per interval.
[SAMPLE={30000|nnnnn}]
Monitoring modes | One CFDATA statement can be specified for each monitoring mode, continuous (CPM) or intermittent (IPM). | |
Sampler and record types | The CFDATA statement controls the CFTS sampler, which produces SMF type 74-4 records. | |
Analyzer statements and reports | CFACT | Coupling Facility Activity Report |
Other BMC Software products | The CFDATA control statement is used by the CMF MONITOR Extractor only. | |
When the coupling facility data collector (CFAC) in MainView for z/OS or CMF MONITOR Online is active, it will use the sample time that was specified on the CFDATA statement. The CFDATA control statement is used even if the data collectors are started with DC=IPM and the CFDATA statement is specified in the CMF CPM session. It is not necessary to specify the CFDATA statement in the CMFIPMxx member. If the CFDATA statement was specified in both the CMFCPMxx and CMFIPMxx members, the CFAC data collector uses the lowest sample time specified. If the CFDATA statement is omitted from both CMFCPMxx and CMFIPMxx, the CFAC data collector uses its default value of 60 seconds.
Parameters
The parameter for the CFDATA control statement is
SAMPLE= | specifies the number of milliseconds between data-gathering cycles for coupling facility data The default is 30000 milliseconds, or 30 seconds. Acceptable values are 5000 to 60000. The specified time will be rounded to the nearest second. |

Example
The CMF MONITOR Extractor collects coupling facility data once every 30 seconds.
