Problem(Abstract)
While investigating a problem with WebSphere Application Server, you may need to watch for events such as messages to the SystemOut.log and take action when they occur.
Resolving the problem
The TrapIt.ear provides an easy way to perform actions based on events(message ids) in the WebSphere Application Server or based on time. If you need to monitor files (for example SystemOut.log, ffdcs, application or operating system logs, and the like), use the trapit shell script for UNIX and Linux systems.
