Can you look at branch bug1826-metrics in my public repository,
particularly at log_unwanted_bytes() where I call the counting function?
Does that look correct to you?

Great! I didn't test my code yet other than running the unit tests. Can
you run this code (if it looks good to you) on your relay for at least
24 hours? It should write a file stats/unwanted-bytes-stats to its data
directory. If it does, we can try to find someone with the default exit
policy to run this code.
