I am running a debian squeeze box with bridge-util and LXC containers.
I guess this is a 2 part request.
- I would like to know what my total bandwidth usage is
- I would like to see it broken down by virtual host.
Hosts all have fixed IP addresses, no DHCP at all.
I came across ntop, MRTG, WireShark but can't figure out which to use, and they all seam so bulky.
What's the best tool to capture usage without interfering with the bridge? I like if it has minimal impact on the overall system, meaning not slowing things down too much, little memory usage etc.
I don't need graphs, just a daily, weekly, monthly total would do.
