I’ve been looking for a way to monitor my various VPS web servers and to automatically reboot them if something goes wrong but I was never able to find a simple solution. I’ve used Monit — but at times it has failed to keep my servers up and running. So I’ve created my own bash script to do the job and thought I would share it.

First, you will obviously need a seperate VPS you can use to monitor your other VPS servers (I’m using an easy TurnKey Linux on mine which is Debian-based so you may need to modify the script based on what you are running).
