Events about problems in Nagios with a duration of less than 1 minute may not be synchronized to Dynatrace As events cannot be closed in Dynatrace, because the Nagios is polled each minute or less.
The problems in Dynatrace are closed automatically after 15 minutes if the status in Nagios does not persist
Ports are not readable from configuration so the Dynatrace custom device has the only IP for interconnections with other Dynatrace objects
Nagios acknowledges are part of Dynatrace event information, not Dynatrace problem
Event properties (Nagios Last check, Nagios Last state change, Nagios Last update) obtain value from the time Nagios plugin poll was executed (Dynatrace problem resend time)
