Hi there,
I'm trying to make sflow accounting work in a large network with a
single sfacctd collector and a lot of agents (routers).
Internet traffic is accounted correctly (the flow only passes one
router), but traffic between clients on two sites are counted double
(the flow is reported from both the involved routers). All routers are
configured to sample ONLY on their internal LAN interfaces - in both
directions.
I need to figure out a way to determine if a flow has been counted
twice, and I thought, including the IP address of the agent in the
database, would allow me to do this.
However, I cannot seem to find, how to enable the logging of the agent
IP in the database - Is this possible? How?
Or should I deal with this problem entirely differently?
Thanks so much in advance.

I was able to find a 6 years old post outlining the same issue i'm facing:
http://www.mail-archive.com/[email protected]/msg00414.html
Still, I'm not sure how to enable the required split between different
agents. Ideally, something like adding an <agent_ip> (by whatever means
- dynamic tagging?) column should solve my problem.
Thanks again.
