How to send errors filtered to a special log file?

[Stefan A.]

Gurus,


For my Application, I have to build a central error file, which will be
parsed by the HP Openview agents for monitoring.
I'd like to write major errors raised by FR also into this file. It would be
enough to have the DB errors in there.
How can I configure FR, that these Messages are appended to this error file?

Thank You.

Regards 
Stefan
