The Buffer Pool Statistics workspaces display current buffer manager performance
information for all monitored queue managers on a z/OS®
system. Data in these workspaces are collected from IBM MQ performance statistics that are written as SMF (System Management Facility) type 115
records. You can use SMF to collect data for these workspaces.
SMF must be running before you can send data to it. For more
information about SMF, see the MVS System Management Facilities
(SMF) manual.
Do the following steps to collect data for the Buffer Pool
Statistics workspaces:
- Use SMF to collect data for monitored queue managers. To
record performance statistics (record type 115) to SMF, specify the
following in the SMFPRMxx member of SYS1.PARMLIB:
SYS(TYPE(115))
You
can also use the
SETSMF z/OS operator command for this.
- Ensure that SMF is running.
- Specify YES on the SMFSTAT (SMF STATISTICS) parameter of
the CSQ6SYSP macro to customize the monitored queue managers.
- Optional: Specify the interval at which statistics
records are produced by setting the STATIME parameter of the CSQ6SYSP
macro.
If you set the STATIME parameter to zero, statistics
records are produced at the SMF global accounting interval.
- Restart the queue managers for the changes to take effect.
