The HDB_DBCC_MDIAGF event is used in SAP to view the merged diagnosis files. Merging diagnosis files allows you to review both trace and log files together. This can be helpful, for example, if you are looking for a specific event, but do not know which file it is recorded in.
Potential Use Cases
This event could be used in the following scenarios:
Look in the HANA DB trace files for a particular record.
View error messages from the trace file over time.
Alert on a specific message in the HANA DB log file.
