Hello, I just started playing with pmacct tonight, so pardon me if these are a stupid question, but I'm wondering if it is possible to do the following things:
* Record (and aggregate on) the address of the router that exported a flow via netflow/sflow. Basically I just want to know which router exported the flow to me, using either the agent address if available (on sflow, etc), or the source address of the netflow packet. * Record (and aggregate on) the src/dst ifindexes that are exported via sflow/netflow protocols. Obviously this would be paired with the router id mentioned above to give the ifindex meaning, :) * Record the mask that was used in a src/dst_net aggregator. I figured out how to dynamically aggregate by the netmask value exported via netflow/sflow (via the pmacct changelog, it doesn't seem to be in the documentation anywhere I could find), but it doesn't record the netmask that was used. For example, say I receive an export for a flow to 1.2.3.4 which has a destination route of 1.2.0.0/16. I want to dynamically aggregate this to 1.2.0.0/16, but currently the only data being stored is 1.2.0.0. This leaves me with no way to know that the dst route was a /16, and probably no way to correctly record the difference between a packet going to 1.2.0.0/16 (for example dst ip 1.2.255.255) and 1.2.0.0/17 (for example dst ip 1.2.0.0). It seems like the netmask would need to be recorded for this to have any chance of working properly. -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ pmacct-discussion mailing list http://www.pmacct.net/#mailinglists
