tor_traffic

Plugin to keep track of the amount of data flowing through your Tor node

Language	perl
Supported platforms	*nix
Written by	Gé van Geldorp

If you can give Tor its own IP address, you can use the ip_ plugins to monitor bandwidth instead for more accurate results (the tor_traffic plugin only samples a 1 second interval, while the ip_ plugins sample the whole 5 min interval)
