WebSphere MQ trace

WebSphere MQ supplies a trace facility that we can use to gather the following information while the queue manager is running:

Performance statistics

The statistics trace gathers the following information to help you monitor performance and tune your system:

  • Counts of different MQI requests (message manager statistics)

  • Counts of different object requests (data manager statistics)

  • Information about DB2 usage (DB2 manager statistics)

  • Information about Coupling Facility usage (Coupling Facility manager statistics)

  • Information about buffer pool usage (buffer manager statistics)

  • Information about logging (log manager statistics)

  • Information about storage usage (storage manager statistics)

  • Information about lock requests (lock manager statistics)

Accounting data

  • The accounting trace gathers information about the CPU time spent processing MQI calls and about the number of MQPUT and MQGET requests made by a particular user.

  • WebSphere MQ can also gather information about each task using WebSphere MQ. This data is gathered as a thread-level accounting record. For each thread, WebSphere MQ also gathers information about each queue used by that thread.

The data generated by the trace is sent to the System Management Facility (SMF) or the generalized trace facility (GTF).
