Connection SummaryΒΆ
The following provides a summary of your relay's inbound and outbound connections. Couple important notes...
To use this you must set DisableDebuggerAttachment 0 in your torrc. Otherwise connection information will be unavailable.
Be careful about the data you look at. Inspection of client and exit traffic especially is wiretapping and not only unethical but likely illegal.
That said, a general overview like this should be fine.
