WireGuard monitoring service for Linux (Debian-based). The primary purpose is to check the WireGuard connection. If the remote server changes its IP address, WireGuard won't reconnect because it only knows the original host used for the initial connection.
The wireguard-monitor service pings the monitored resource, and if it goes down, the script restarts the wg-quick@wg0 service.
replace 10.10.10.1 by internal WireGuard peer ip
replace 5 by time in minutes to initiate restart (example: 1 or 10 or ...)
./install.sh 10.10.10.1 5
