Monitoring.sh - born2beroot (Debian flavour)

This script has only been tested on Debian environement. It uses jc and jq to parse the commands to JSON, and then select the proper data to output. You must install them before trying the script. Warning: ifconfig has been configured to use the Debian 5.10 path. It would not work on Ubuntu or others distributions.
