Provided are an execution monitoring tool, a method and a computer program
product for monitoring a message processing program or system. The
execution monitoring tool identifies locations within the message
processing program corresponding to a predefined set of execution progress
stages, and inserts execution progress report generator components at
these locations. Execution progress reports (including a representation of
the message contents and structure) are then sent to the execution
monitoring controller which maps the report data to its own representation
of the program to determine the current position within an execution
program. The message contents and structure, as well as the structure of
the program and the current execution position, are displayed during
execution on a test system. The execution reports include the current
execution status as well as the position within the execution flow.
