Ftrace histograms, based on triggers and synthetic events were implemented few years ago by Tom Zanussi. They are very powerful instrument for analyzing the kernel internals, using ftrace events, but its user interface is very complex and hard to use. This proposal is to discuss possible ways to define more easy to use and intuitive interface to this feature, using trace-cmd application.
