Description
My coworker thought using 8.8.8.8 for the gateway monitor would suffice for a “is the internet up” monitor. Well, google rate limited us and I spent hours looking for the right approach.

Ultimately, it seems using ICMP for monitoring against public DNS, NTP, etc. servers is the wrong approach for some use-cases. Cisco’s IP SLA has the ability to perform a number of health checks from many protocols, so I set out to find something comparable for FreeBSD. Tcprtt looks like it could be a good solution for internet uptime monitoring that does not rely on ICMP.
Does this seem like a viable solution?
