We recently got a lot of false system down alerts when the monitoring machine had high network traffic due to backups. What was strange is that none of the systems being monitored across the metro Ethernet WAN showed down, only those in the same subnet (and same room!) as the Dell Essentials box.
I think the timeouts and retries used same defaults for all monitored servers. Does Essentials automatically allow for a slower response from devices outside the local subnet?
Our version is 1.0.1.1253.
