Monitoring WAN Connection and Rebooting Firewall if disconnected

[Pocket_Sevens]

Good afternoon all.  I used to have a CRON job that would run every 15 minutes to do a "ping check" to make sure my OPNSense router can still reach the internet and, if it couldn't, reboot my device to get a clean connection.  This was handy if I was on the road because I need the router to reboot if connectivity stopped working and I wasn't home to do it.

I'm wondering if there's a better way to do this using another tool to check the WAN to see if I lose connection to the internet and have the router reboot.  I think I read somewhere that someone is using MONIT to do this, but I haven't used MONIT before.  Am I correct on that?  If so, how would I configure?

Thank you for any assistance in advance.  :)
