Dashboard states reflect the results of monitoring (i.e. the most recent monitoring result for that device)
Undefined state. An undefined state is rare. Typically, it is caused by transit delays for monitoring results. An undefined state only happens when every monitoring agent involved in the monitoring for a device indicates a state as “Undefined”. In order to report an undefined state for a device, an agent should NOT receive any response for a device for a set time period.
This set time period is calculated based on the following formula:
Undefined Duration = (Agent number + 1) x monitoring frequency + 15 minutes
So, with each update of the Dashboard Dotcom-Monitor determines whether or not there was any response based on the “undefined duration” calculation. If there were no responses it switches the state to “Undefined”.
