Understood and thanks for all the help! I have dug deep into the source my
self and was hoping to get some clarification on my approach, I am pretty
familiar with the code base now so thoughts that may pop up to investigate
further is just fine.

Alright, the reason is that we've built a activity monitoring system on top
of cassandra, hadoop & hive, and want to reuse the same for all analytics
related webapps too. I understand that we can use a tool that process logs,
but that means we need to bring in more external tools, plus we are
extracting more data for our analytics stuff, in the valve we've written.

On the other hand AccessLogValve is a valve, in my understanding we should
be able to write another valve and extract stuff similar to the way its
done in ALValve. However in the custom valve we've written the output are
different, hence my query as to the inconsistent behavior ...
