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.

CFDATA
[SAMPLE={30000|nnnnn}]

Best Practice

To collect synchronous data from all systems to which the coupling facility is connected, BMC Software recommends that you use the SYNCH=SMF parameter of the CMF MONITOR Extractor REPORT control statement.

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.

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

CFDATA

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