Monitoring application performance
CICS® monitoring provides information about the performance of your application transactions. Use the MONITOR command for user event monitoring points.
In addition to the monitoring data collected from a system defined
elsewhere, monitoring points (EMPs) in CICS, a user application program
can contribute data to user fields in the CICS monitoring records. You can do this by using the MONITOR POINT
command to invoke user-defined EMPs. At each of these EMPs, you can
add or change up to 16384 bytes of your own data in each performance
monitoring record. In those 16384 bytes, you can have any combination
of the following:
- In the range 0 - 256 counters
- In the range 0 - 256 clocks
- A single 8192-byte character string
For example, you could use these user EMPs to count the number of times a certain event occurs, or to time the interval between two events.
