Hi Raphael, Thanks for your kind words about the pmacct project.

For sure you have to maintain a map to say what is input and what is output - would be great to find a way that is as most static as possible for you. What comes to mind for the purpose - all depends whether you have downstream ASNs, get at least a BGP feed or get src_as and dst_as populated from NetFlow, get MAC addresses from NetFlow, etc. - is you can use ASNs, IP prefixes, MAC addresses or interfaces (this last one is what you are doing at present). For example, should you not have downstream ASNs and get src_as and dst_as correctly populated by your router(s) via NetFlow you could simply match input traffic as dst_as=0 and output traffic as src_as=0 in your pre_tag_map. > Side question about pretag filter ? the "tag" field in sql is always > at '0' ? This is not blocking but I wonder why ? Is 'tag' part of your aggregation scheme, ie. 'aggregate' keyword in your config? If not, then that's the reason and zero is simply the default value imposed to the field in the SQL schema. > Another question about BGP src_as and dst_as fields : > Depending on the direction the src_as or the dst_as are correclty > filled, but not the other which is always '0' ?

You won't see your own ASN number being filled in - just like you don't see it in your own BGP routing table. But you can make some tricks, ie. use a networks_map, to do that. Let me know if interested. Cheers, Paolo _______________________________________________ pmacct-discussion mailing list http://www.pmacct.net/#mailinglists
