Sorry for not answering any sooner. I was somewhat distracted by other
things (like preparing my presentation for Nordic Nagios Meet where I'm
sitting right now :)

The attribute value of the name attribute in the program element serves
only to document the database, it is not used for matching.

The important part is <pattern></pattern> inside the program element.

I tested your db snippet, and the problems were:
  * if you don't specify, logger will send "<someone>" as the program
name, so please use "logger -t logger"
  * you need to specify "logger" enclosed in "pattern" tags.

In that way I got your pattern to match.

Robert has worked on documenting db-parser(), I just didn't have time to
review it yet, however he told me he'd publish a draft of the
documentation, so you can have it earlier, and possible fix

Robi, can you post the URL for the draft docs here?
