Interpreting IBM MQ for z/OS accounting data

IBM MQ for z/OS accounting data is written as SMF type 116 records. Use this topic as a reference to the different types of accounting data records.

IBM MQ accounting information can be collected for the following subtypes:

0

Message manager accounting records (how much processor time was spent processing IBM MQ API calls and the number of MQPUT and MQGET calls). This information is produced when a named task disconnects from IBM MQ, and so the information contained within the record might cover many hours.

1

Accounting data for each task, at thread and queue level.

2

Additional queue-level accounting data (if the task used more queues than could fit in the subtype 1 record).

10

Accounting data for channels. Note: Accounting information for specific channels can be enabled or suppressed by the STATCHL channel attribute, and the STATACLS queue manager attribute.

Note that:

• Subtype 0 records are produced with accounting trace class 1.
• Subtype 1 and 2 records are produced with accounting trace class 3.
• Subtype 10 records are produced with accounting trace class 4.
