Help with Log Monitor

I need some help configuring the log monitor, primarily with syntax.

Is this correct:

LOG /opt/myapplication/system.log %Incompatible types|WSVR0605W|OutOfMemoryError|Assertion|AppointmentDate from the VO(String) is not matching with the Date from the Slot SEq ID COLOR=RED

I'm guessing not. How do I put log lines that developers are specifically looking for. In this case they want to alert on:

"AppointmentDate from the VO(String) is not matching with the Date from the Slot SEq ID"

Thanks for the help.....James
