Monitor multiple WAN Gateways

[jfou1987]

Hello,

Hope my question wasn't already asked, but i didn't found any exact situation.

I have 3 ISP connected, each monitored to a DNS IP (8.8.8.8/1.1.1.1/1.0.0.1)
Failover is working fine. But i'd like to receive and email when each connection goes down and when it goes up again.

The default gateway alert in the monit service settings only notify me when one is going down. If an other one is going down, i didn't received information. Of course, in this case, one connection is still available to send out the e-mail.

Is there anybody found a suitable option to monitor this crucial information ?
