Overview
Down and dirty mini status viewer. Makes it easy to monitor several different sections of a server at the same time.
Useful for monitoring a server that is having problems.
The main concept is to minify the output of several sections in to a small terminal window, useful for monitoring a server when it is having problems or could at some point.
Auto adjusts output based on size of the terminal.
Script
