Sean Brown:

I just set up a new non-exit relay and in going through information to set up, I came across the T-shirt for contributing and in addition to running for 2 months it says "if you're not an exit but you average 500 KBytes/s traffic."

What would be the best way to keep accounting of the traffic my relay is passing? I know of the metrics.torproject.org, is that all the project would need?

For your own personal records, you could look into using vnstat or nyx. I use a cron job to update my relay's webpage[1] with some traffic stats from vnstati, a tool that makes images using data from vnstat. Example here[2] (scroll down). This is just for my own fun, though.

I presume whoever runs tshirt@torproject.org is going to use the Relay Search tool on metrics. Check out the sources webpage[3] for more info on how that data is collected.

For anyone else interested in these t-shirts, see this webpage for more information[4].
