there's many ways to do it.
The myfilter.conf file gives options for pre-processing your log file.
Look at /usr/share/logwatch/default.conf/services/*.conf for examples.
Look at arpwatch.conf for a simple example. Note the "OnlyService" and
the "RemoveHeaders" lines. They are probably similar to what you want
if you are pulling lines from /var/log/messsages.
Then look at some files in /usr/share/log/watch/scripts/service.
I like the 'afpd' as an example of how to grab data from the lines
you are looking at.
In your /etc/logwatch/scripts/services directory, make sure the
permissions are 644 -- they are not executable.
This should be enough to get you started. Report back with more specific
problems for more specific help.
Good luck

Thanks Rich,
I followed the examples, but when I tried "logwatch --service myfilter" I was geting an error:
Logwatch does not know how to process service: myfilter
I solved THAT by correcting the name of myfilter in /etc/logwatch/conf/services from myfilter to myfilter.conf
Now it's working.... now I can concentrate on the actual report. :-)
Cheers!
So, for anybody else looking to add a report section in logwatch
your filter config file goes here: /etc/logwatch/conf/services and must be named <service>.conf
the actual filter goes here: /etc/logwatch/scripts/services and must be named <service>
Where <service> is whatever you want to call it... it just has to be the same in both places... makes sense.
Then logwatch --service <service> will produce your report.
The filter itself is assumed to be written in Perl, so use Perl syntax in your filter script. Apparently you can configure a different languagein the .conf file, but I didn't bother figuring that out... it was simpler to do what I need in Perl than to figure out the nuances of Logwatch configuration. ;-)
Now that I've actually done it once, it seems pretty simple... so why did it appear so complicated in the doc? hmmm.
