In what scenario might Dynatrace be unable to identify an application's host name automatically?

Dynatrace may be unable to automatically identify an application's host name particularly in scenarios where the application operates behind a firewall with a different host name. This situation presents a challenge because Dynatrace relies on the ability to communicate with the application's environment to gather data, including network details such as the host name. When an application is behind a firewall, the host name that Dynatrace would detect may not align with the actual external or internal name that users or other systems access. As a result, the mismatch prevents Dynatrace from establishing proper monitoring and gathering accurate availability and performance metrics for the application.

Other scenarios, such as updating the application or insufficient server capacity, do not inherently affect Dynatrace's ability to identify the host name. Similarly, the absence of a user interface does not impact the monitoring of the application's performance metrics or host name resolution; Dynatrace can still perform backend monitoring regardless of UI presence. Therefore, the situation involving a firewall and a differing host name is the most relevant to the question regarding automated host name identification.
