Setup pmacct without BGP on a simple A-B Linux router? about pmacct

Hi @RoFz ,

What you are trying to achieve is indeed possible: no BGP so, as you said, you define a networks_file where you list subnets of interest one per line, link such file in the config, ie. networks_file: /path/to/networks.lst, and set aggregate: src_net, dst_net for a test -- this config should show the traffic in between the subnets you did define in the file.

As per labelling, unfortunately that feature got dropped -- i refer to the one where you could define strings like foo or bar in the networks_file and would see those accounted traffic for, instead of the actual defined subnet. The feature was clumsy and it is definitely something better done as part of a lookup when post-processing data.

Should you want some form of grouping of subnets, you could still group them using ASNs (say private ones). You could refer to the following section of the example:

65500,192.168.1.0/24
65501,192.168.2.0/25
65502,192.168.4.0/23

Now if you, again for a test, configure aggregate: src_net, dst_net, src_as, dst_as then you should see both the subnets and the ASNs (which in this case are just numerical groups of subnets). Should you then want the ASN be translated into strings like foo, bar, etc. then you need to do it in the post-processing but now it's much easier as groups are made ready and it would be a trivial task of 1:1 translation.
