+## LAST UPDATE
+Added a new metric called "service_openvpn" which is quite simple : if the openvpn service is up/active, equals 1. If not, equals 0.
+Added a script that restart automatically if he sees a change on the openvpn service with the help of "systemctl is-active --quiet" that returns an exit code if it's active.
