Monitoring functions
There are two XPI monitoring functions. These are the DFHMNMNX calls
MONITOR and INQUIRE_MONITORING_DATA.
DFHMNMNX calls cannot be used in any exit program invoked from any global
user exit point in the:
v Dispatcher domain
v Dump domain
v Monitor domain
v Statistics domain
v Transient data program.
INQUIRE_MONITORING_DATA calls cannot be used in any exit program invoked
from any global user exit point in DFHTCP or DFHZCP (that is, at any of the exit
points named “XTCx...” or “XZCx...”).
The MONITOR call
The MONITOR XPI call is similar to the EXEC CICS MONITOR command. It
enables you to invoke user event-monitoring points (EMPs) in your exit programs.
