The monitoring control table (MCT) defines the user data fields
in CICS® monitoring
performance class records, and describes how they are to be manipulated at
event monitoring points (EMPs). It also controls which system-defined performance
class data fields are recorded. See the CICS Performance
Guide for details of the MCT and performance.
The MCT is required only if:
- You invoke EMPs in your application programs
- You need to exclude specific system-defined fields from being recorded
- You want to use monitoring resource classes.
- You want to collect additional monitoring performance data for the resource
managers used by your transaction.
If no MCT is present in the CICS region, CICS assumes the following defaults:
- The performance, transaction resource, and exception monitoring classes
are available.
- All CICS system-defined data fields are collected.
In your application programs, you can invoke EMPs
using the EXEC CICS MONITOR command.
The MCT consists of the following macro instructions:
- Control section—DFHMCT TYPE=INITIAL
- User event monitoring points—DFHMCT TYPE=EMP
- Control data recording—DFHMCT TYPE=RECORD
- End of monitoring control table—DFHMCT TYPE=FINAL (described in TYPE=FINAL (end of table))
