common method to count traffic volume on IX

[m4rtntns at gmail.com (Martin T)]

Hi,

many Internet exchange points post publicly available graphs which
describe aggregated traffic volumes on IX. For example:

Netnod: http://www.netnod.se/ix-stats/sums/
AMS-IX: https://www.ams-ix.net/technical/statistics
LINX: https://www.linx.net/pubtools/trafficstats.html


Is there a common method to count this traffic on a switch-fabric?
Just read all the switch interface "packets input" counters with an
interval to get the aggregated input traffic and read all the switch
interfaces "packets output" counters to get the aggregated output
traffic?


regards,
Martin
