Attempting to generate a traffic graph to monitor tunnel traffic between two vps'es.
two servers: 184.108.40.206 & 220.127.116.11
111 is an app server, 222 is a db server.
Proper iptables rules are in place to allow 111 & 222 to communicate.
I have a tunnel created on 111 to connect to the db server via localhost:4002.
I'd like the monitor the traffic that traverses this tunnel with Munin.
On 111, Tried using the ip_ plugin with no success:
- ip_222 - graph appeared, no traffic.
- ip_127.0.0.1:4002 - no graph appeared at all.
- ip_127.0.0.1 - graph appeared but nan values.
Perhaps ip_ isn't the right plugin. What should I use?
