Which of the following conditions would lead to a service not showing in Smartscape?

A service not appearing in Smartscape is primarily due to a lack of communication over an extended period. When a service does not communicate for 72 or more hours, it indicates that the service is likely inactive, unavailable, or has experienced significant issues that have rendered it unable to report its status to the monitoring solution.

Smartscape is designed to display services that are actively communicating and generating analytics. The absence of communication for such a considerable timeframe signals to Dynatrace that there is no active data to visualize. This is crucial for maintaining an accurate and real-time representation of the system architecture that Smartscape provides.

In contrast, while no communications for 24 hours or the absence of analytics data might indicate potential issues, they may not be sufficient to warrant the complete removal of the service from Smartscape. The lack of users accessing the service does not inherently affect the service's operational status; it may still be functioning but simply not handling requests at that moment. Therefore, sustained inactivity for an extended period is the most definitive condition for a service not appearing in Smartscape.
