The CICSplex Log Stream Analysis attributes report on the configuration and performance data for every z/OS log stream that is connected to CICS. Use the CICSplexLog Stream Analysis attributes in situations to quickly analyze the performance of any connected log stream. These attributes provide data for the Log Stream Analysis table view.
Auto Delete The log auto delete indicator. If set to Yes, the z/OS Logger automatically deletes the data as it matures beyond the retention period, irrespective of any log stream delete calls. If set to No, the data is only deleted when a log stream delete call is issued and the data has matured beyond the retention period. These are the valid values: Yes and No.
Average Bytes Written The average number of bytes written to this log stream per request. The value format is an integer.
Browse Reads The number of browse read requests issued for this log stream. If the log stream is not part of the System Log, this field contains the value n/a, as it cannot be browsed. The value format is an integer.
Browse Starts The number of browse start requests issued for this log stream. If the log stream is not part of the System Log, this field contains the value n/a, as it cannot be browsed. The value format is an integer.
Buffer Appends The number of occasions on which a journal record was successfully appended to the current log stream buffer. The value format is an integer.
Buffer Full Waits The number of times buffer full has occurred for this log stream. The value format is an integer.
Bytes Written The number of bytes written to this log stream. The value format is an integer.
CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS operating system has a unique name. This name is an alphanumeric string, with a maximum of eight characters, and case-sensitive. CICS region names are always in uppercase characters.
Current Waiters The current number of force waiters for this log stream. The value format is an integer.
DASD Only Indicates the type of log stream. If set to Yes, the log stream is of type DASDONLY. If set to No, the log stream is of type coupling facility (CF). The value format is an integer.
Force Waits The total number of force waits for this log stream. The value format is an integer.
z/OS Log Stream Name The name of the log stream. The value format is an alphanumeric string, with a maximum of 26 characters.
Origin Node The combination of z/OS System ID (SMFID) and CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case-sensitive.
When a situation is true, the system compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.
Max Block Length The maximum block size allowed by the z/OS Logger for the log stream. The value format is an integer.
Peak Waiters The peak number of force waiters for this log stream. The value format is an integer.
Retention Period The log stream retention period (in days) for which data must be kept before it can be physically deleted by the z/OS Logger. The value format is an integer.
Retry Errors The number of occasions on which the z/OS system logger retried errors occurred when a block of data was being written to the log stream. The value format is an integer.
Statistics Last Reset Indicates the last time that log stream statistics were reset, possibly because of interval statistics collection. The value format is an integer.
Stream Deletes The number of delete (IXGDELET) requests issued for this log stream. If the log stream is not part of the System Log, this field will contain the value 'n/a', as it cannot be deleted. The value format is an integer.
Stream Status The current status of the log stream. These are the valid values: Failed and OK.
Structure Name The coupling facility (CF) structure name for the log stream. The structure name is only applicable to coupling facility type log streams. The value format is an alphanumeric string, with a maximum of 16 characters.
System ID Indicates the 4-character name that uniquely identifies an active z/OS operating system within a given CICSplex. The value format is an alphanumeric string, maximum 4 characters, and case-sensitive. z/OS System IDs are always in uppercase characters.
System Log Indicates whether the log stream forms part of the System Log. These are the valid values: Yes and No.
Use Count The current use count of the log stream. The value format is an integer.
Write Requests The number of IXGWRITE requests issued to this log stream. The value format is an integer.
