Logstream: Summary resource statistics
These statistics fields contain the logstream summary resource data. Summary statistics are not available online.
| DFHSTUP name | Description |
|---|---|
| Log Stream Name | The logstream name. |
| System Log | Indicates if the logstream forms part of the System Log. |
| Structure Name | The coupling facility (CF) structure name for the logstream. The structure name is only applicable to coupling facility type logstreams. |
| Max Block Length | The maximum block size allowed by z/OS® System 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 | The logstream retention period (in days) that the data must be kept before it can be physically deleted by z/OS System Logger. |
| Auto Delete | The log data auto delete indicator. If set to YES, z/OS System 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 | The total number of DELETEs of blocks of data from the logstream. For non-system logs, the report shows N/A here, as CICS® does not issue Log Delete requests against non-system logs. |
| Log Query Requests | The total number of queries that CICS made to check the status of the logstream. |
