Monitoring field descriptions

Transaction timing fields
The CMF performance class record provides detailed timing information for each transaction as it is processed by CICS®. A transaction can be represented by one or more performance class records, depending on the monitoring options that are selected.
Transaction response time
You can calculate the internal CICS response time by subtracting performance data field 005 (start time) from performance data field 006 (stop time).
Transaction dispatch time and CPU time
The transaction total dispatch time field USRDISPT, field 007 in group DFHTASK, is the total elapsed time during which the user task was dispatched by the CICS dispatcher domain on each CICS TCB under which the task executed.
Transaction wait (suspend) times
The CMF performance class record provides a breakdown of the transaction suspend (wait) time into separate data fields. You can use these to calculate various wait times.
Program load time
The program load time is the program fetch time (dispatch time) for programs invoked by a transaction.
RMI elapsed and suspend time
The RMI elapsed time and suspend time fields provide an insight into the amount of time that a transaction spends in the CICS resource manager interface (RMI).
JVM elapsed time and suspend time
The JVM elapsed and suspend time fields provide an insight into the amount of time that a transaction spends in a Java™ Virtual Machine (JVM).
Syncpoint elapsed time
The syncpoint elapsed time is the elapsed time the transaction spent processing a syncpoint.
Storage occupancy counts
An occupancy count measures the area under the curve of user-task storage in use against elapsed time.
Program storage
The level of program storage that is in use is incremented at LOAD, LINK, and XCTL events by the size (in bytes) of the referenced program, and is decremented at RELEASE or RETURN events. On an XCTL event, the program storage currently in use is also decremented by the size of the program issuing the XCTL, because the program is no longer required.
