MQTT-TOPN: display MQTT topic statistics

Overview

This is a simple MQTT subscriber client in Go to display topic performance statistics with TopN most "chatty" topics. The idea is similar to the Unix "top" process statistics utility detailed at https://www.geeksforgeeks.org/top-command-in-linux-with-examples/ .

It is the command-line interface equivalent of https://github.com/gambitcomminc/mqtt-stats implemented with Go ncurses https://godoc.org/github.com/gbin/goncurses

This utility allows you to analyze quantitatively the published topics underneath a wildcard topic and answer such questions as "which topic generates the most messages?" and "which topic generates the most traffic?". You can sort by messages/second to get the most active topics.

Open-source, free, code is at https://github.com/gambitcomminc/golang-mqtt-topn
