channel_stats plugin collect the runtime statistics (speed, request count and
more in the future) for each channel. The stats is exposed with http interface
in json. (The code of interface is from 'stats_over_http' plugin.)
In general, the plugin could be used on reverse proxy with a fixed number of
remap rules. It's not design for the proxy which serves unlimited channels (
open-relay forward proxy).
