»ADMLogger is a log analyzing engine based on 'fireparse.'
After I had written fireparse, I had found myself writing little
scripts based on it. Like one that told me what my FTP server did
that day. And then more things like - were unauthorized machines
trying to get IP addresses from my DHCP server? So I decided to rip
out the 'engine' of fireparse to create a generic log analyzer
system. Using this core, I could easily build upon it with plugins.
This also made it easier on my systems since there was now only one
entry for cron, and I didn't have different code everywhere - a bug
fix in fireparse had me searching the rest of my systems looking to
see if I still used that line« (aaron.marasco.com/linux.html,
