Server resources usage Policy report format from IDS

Hi list,
I have been assigned a task to write a plug-in for an IDS, which should
be capable to report maximum information about the usage of the
web-server(or web-site) resources.
HTTP requests( HTTP methods/URI/Path/Files accessed/???),
Query parameters & values, Message body in case of POST request.,
Source IP,
Host Header,
User-Agent Header, etc
Though the report should contain all information @ the each user/ip
accessed that perticular site, it should be small to process on &
extract the information.

ne hints / suggestions welcome.

~~Thanks in advance.
