The monitoring control table (MCT)
You can use the monitoring control table (MCT):
v To tell CICS about the EMPs that are invoked by your application programs and
about the data that is to be collected at these points. The DFHMCT TYPE=EMP
macro can do this.
v To tell CICS that you want specific system-defined performance data not to be
recorded during a particular CICS run. The DFHMCT TYPE=RECORD macro can
do this.
Full details of the DFHMCT macros are provided in the CICS Resource Definition
Guide, and you should refer to this when reading the following sections.
