What qualifies as an external service in Dynatrace?

In Dynatrace, an external service is defined as any service that is not directly monitored by Dynatrace OneAgent. This includes third-party APIs, cloud services, and any other services that your application interacts with but do not have the OneAgent installed. The OneAgent captures a wide range of metrics and insights from the applications it monitors, but when interactions occur with external services that fall outside of that direct monitoring scope, these interactions are categorized as external.

This distinction is important because it helps organizations understand performance impacts and dependencies not only from their own applications but also from services they rely on outside of their direct control. External services can signify potential bottlenecks or issues in the overall architecture, impacting user experience and application functionality.

Other options specify limitations that do not reflect the broader definition of what constitutes an external service, such as focusing only on specific types of services (like databases or server services) or limiting the scope to internal application services. Thus, recognizing external services as any service not directly monitored by the Dynatrace OneAgent encompasses a wider understanding of how applications interact with various components in their execution environments.
