Problem

-- Message-related information, such as parsing failures, mapping failures, file transfer failures, and so on are logged in the Message log, not in the trace file

-- if Sentinel is not used to monitor the system, how to automate the error handling ?

Resolution

* export your favorite search in Message Log (my_search.lql) : for instance, filter the error entries

* write a script which
- execute Integrator profile
- run the ml_report.x4 : r4edi ml_report.x4 -L my_search.lql > ml_txt
- parse the output file
- execute the required actions (send email to alert the operation team, ...) in case a new error occurs

* execute the script periodically (in a cronjob for instance)
