Logging pretty much all Attribute Value Pairs

Hi All: I have this requirement to log pretty much log all attribute value pairs. I put a hook in radius.c and looged few parameters that was available to me UserName, Source IP Address, Destination IP Address, NAS-IP-Address, Request-ID. I use vp_prints function to parse packet->vps, then save it and insert in DB. In normal circumstances not all attributes are used but I am going to use this list: http://www.iana.org/assignments/radius-types/radius-types.xml I will use this list to code and extract attribute value pairs and store in DB. Please let me know my assumptions are correct and also let me know if there is a better way todo things or a complete implementation is already included in FreeRadius. Thanks in advance -Gyan
