How to configure logwatch to monitor a custom log file

Ubuntu Server 9.10

Hi Guys,

Could someone point me to some instructions for how to get logwatch to monitor a custom log file? I have a dropbox solution that documents uploads/downloads to a log file and would like to include it in the updates from logwatch.

I tried creating a custom conf file in /usr/share/logwatch/default.conf/logfiles/ but it doesn't seem to be working...

A starter point is the LogWatch Documentation page for HOWTO Customize LogWatch.
Read through points 4, 5 and 6.

Another brief description of the LogWatch files -- Managing your log files.
And, a Metalog wiki reference on how to setup logwatch to read metalog generated log files.
