      http://mms.mongodb.com/help/monitoring/faq/#what-happens-if-a-monitoring-agent-becomes-unavailable-how-can-i-ensure-my-mongodbs-are-always-monitored

      Our doc's are incorrect about what triggers an "agent down" alert.

      Currently we state:

      The monitoring agent is fairly robust, and MMS automatically sends an Agent Down alert when a monitoring agent becomes unavailable. However, once you have completed your initial MMS setup, a second monitoring agent can be added. If one monitoring agent fails, the other can continue monitoring.

      This is incorrect, as MMS Agent Down alerts will only be triggered when there are 0 of X agents detected as available for a given group. Not when any single agent is down.
