Nice tutorial from Initial State‘s Learning How to Build Real IoT Applications series:
If you are using one or more Raspberry Pis to run a dedicated task (such as monitoring who’s at home or the weather or your beer fridge), you need those processes to run uninterrupted. A task that exits unexpectedly may need your immediate attention to avoid lost data, project delays, or a system failure. It is impractical to manually babysit a bunch of Pis to make sure everything keeps running. A better way to ensure continuous operation is to be alerted when a process exits and be able to pull up a single dashboard at anytime to see the status of every important process running on every one of your deployed Pis.
In this tutorial, we will use a couple of simple scripts to:
- create a web-based dashboard that monitors the status of multiple processes
- configure our Pi to launch the dedicated process and its monitor on boot
- create an email/SMS notification when a process exits
