Automatically Restarting Server If Jetpack or wordpress plugin reports site is down

Hosting WordPress sites on virtualmin and Jet pack reports site is down. How Can I trigger an automatic recovery or a server reboot or something similar. I have been given to understand this needs to be undertaken under webmin> System and server status> and then add a monitor type. What monitor type am i looking to add and what command should I be using to initiate the process and get the desired result.
