Subject: [Ntop-dev] AS RRD data dump

Hello All,

I'm in need of gathering persistent statistics based on AS number similar to the way it is currently done with domains. I figured I'd take a stab at modifying the rrdplugin using the Domain dump as a reference as referred to by Burton. I've done most of that but have run into a little snag. Domains are easily looked up via DNS whereas AS's are not. I believe the current way to do this is using the AS-list.txt file, but I have no idea how it gets manipulated currently.

I'm by no means a developer, but I'm willing to hack through and see what happens. Can anyone point me in the right direction as to how/where the AS-list.txt file is manipulated to group the AS stats under Summary/ASN Info so that I can attempt to get these stats into RRD?

Also, has anyone already played around with this idea? Figured I'd ask just in case, wouldn't want to try to re-invent the wheel.

Thanks in advance!
