RPi-Monitor: Version 2.x advance usage and customization

Edit: RPi-Monitor version 2.7 introduce a change in configuration name and location:
  • /etc/rpimonitor d.conf becomes /etc/rpimonitor/daemon.conf
  • /etc/rpimonitord.conf.d becomes /etc/rpimonitor/data.conf
  • /etc/rpimonitord.conf.d/*.conf becomes /etc/rpimonitor/*.conf

In this article we will see how to do the things described in RPi-Monitor: Advance usage and customization and maybe, a little bit more...

We will then answer the same questions : How should I do if I want to...
  • Customize RPi-Monitor v2.x to fit a particular needs?
  • Use it with my own Web Server? 
  • Add "friends" linking RPi-Monitor v2.x running on different platform together?
  • Use it into another Linux distribution than Raspbian? 
  • Add other graphs from additional sources (other mount point or external temperature probe)?
