WebSphere MQ trace
WebSphere MQ supplies a trace facility that you 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).
