I just want to touch this one point below, and then I’m done.
If you’re running your entire organization on a single DNS server, then you shouldn’t even be working in this industry.
There are certain fundamental components in any network infrastructure that should be redundant. DNS, by far, is high on the list of those components. You should *always* have multiple DNS servers redundant to each other. Maybe even have redundant load balancers front-ending those DNS servers. That’s even more true when you’re hosting/running authoritative DNS servers for certain domains. Whatever NMS you choose to run, even that isn’t as high a priority for redundancy.
It all goes back to good network and server architecture and design. If you don’t have a solid base for all that, then all the higher level stuff is just going to fold like a house of cards. If you spend the extra time to do things right and not half-assed, then you’ll have a solid network and have good reporting on everything. Don’t be that half-ass guy.

What if my DNS server, that is a monitored server as well fails?
