Table 1. Logstream: Summary resource statistics
DFHSTUP name Description
Log Stream Name is the logstream name.

 

System Log indicates if the logstream forms part of the System Log.

 

Structure Name is the coupling facility (CF) structure name for the logstream. The structure name is only applicable to coupling facility type logstreams.

 

Max Block Length is the maximum block size allowed by the MVS Logger for the logstream.

 

DASD Only indicates the type of logstream. If set to 'YES' the logstream is of type DASDONLY. If set to 'NO' the logstream is of type coupling facility (CF).

 

Retention Period is the logstream retention period (in days) that the data must be kept before it can be physically deleted by the MVS Logger.

 

Auto Delete is the log data auto delete indicator. If set to 'YES' the MVS Logger automatically deletes the data as it matures beyond the retention period, irrespective of any logstream delete calls. If set to 'NO' the data is only deleted when a logstream delete call is issued and the data has matured beyond the retention period.

 

Log Delete Requests is the total number of DELETEs of blocks of data from the logstream. For non-system logs, the report will show 'N/A' here, as CICS® does not issue Log Delete requests against non-system logs.

 

Log Query Requests is the total number of queries that CICS made to check the status of the logstream.
