The by far easiest way to fix the logging issues would be to hack up 
nagios to only log to stdout, and then store everything in a pretty much 
flat SQL database. Then you can rewrite the cgi's in a webfriendly 
language with excellent database and hashing support (PHP comes to mind).

Flush the database to disk every other month or so, and just live with 
the fact that the yearly report takes an hour or two to create. It's not 
like you do it every day anyway.

I've been thinking about doing this myself for some time now, but just 
like you, I just can't find the time to do it.
