Thread level accounting records are collected for each task using WebSphere MQ. For each task, a thread-level accounting data record is written to the SMF when the task finishes. For a long running task, data is also written at the statistics interval set by the STATIME parameter of the CSQ6SYSP system parameter macro (or by the system SMF statistics broadcast), provided that the task was running the previous time statistics were gathered. In addition, accounting information is gathered about each queue that the task opens. A queue-level accounting record is written for each queue that the task has used since the thread-level accounting record was last written.
Thread-level and queue-level accounting records are produced if you specify class 3 when you start the accounting trace.
The thread level accounting information is written to an SMF type 116, subtype 1 record, and is followed by queue-level records. If the task opened many queues, further queue information is written to one or more SMF type 116 subtype 2 records. A thread identification control block is included in each subtype 1 and 2 record to enable you to relate each record to the correct task. Typically, the maximum number of queue-level records in each SMF record is about 45.
The format of the thread-level accounting record is described in assembler macro thlqual.SCSQMACS(CSQDWTAS) and in Table 25. The format of the queue-level accounting record is described in assembler macro thlqual.SCSQMACS(CSQDWQ) and in Table 26. The format of the thread identification record is described in assembler macro thlqual.SCSQMACS(CSQDWTID) and in Table 27.All these records are also described in C header file thlqual.SCSQC370(CSQDSMFC). The field names in C are all in lower case, for example wtas, wtasshex.
