I don't know the specific documentation you are referring to but I can 
hazard a guess. The DNS information, and proper functioning of the DNS 
servers, may be among the very things you are trying to monitor. If the 
DNS portion of your network is failing then you will lose telemetry on 
all nodes identified by DNS names which will make identifying the 
problem harder..

I have some other comments on the check_dns plugin which I'll put in 
another thread.
