What is rttMonHTTPStatsDNSServerTimeout?
This counter tracks failed DNS lookup attempts during synthetic HTTP monitoring, counting requests that timed out while contacting the DNS server. It reveals DNS availability and performance issues that degrade HTTP service quality, separate from web server problems. An operator diagnosing why web-based applications fail intermittently would check this counter to rule out DNS timeouts.
Examples
