Display Mitmproxy's Events Log on Linux
The eventlog can be viewed by pressing E
(Shift+E) when in mitmproxy.
Okey finally I just found out the solution myself ...
From the mitmproxy console, type :console.view.eventlog
Turned out to be pretty easy, but I still think that such information should have been provided either on linux manual pages of mitmproxy or on its docs website, by the way.
