Which metric is NOT typically included in the "Service or Request" dashboard tile?

The correct choice reflects that "Traffic volume between hosts" is not usually part of the "Service or Request" dashboard tile. In Dynatrace, the "Service or Request" dashboard tile primarily focuses on metrics that pertain directly to the performance and health of the specific services and requests being monitored.

Metrics like "Requests per minute," "Failure rate," and "Response time" are essential for assessing how well a service is performing. They provide insights into how frequently a service is accessed, the proportion of unsuccessful requests, and the time it takes to respond to each request, respectively. These metrics directly relate to the user experience and operational efficiency of the service.

On the other hand, "Traffic volume between hosts" generally pertains to network performance and infrastructure monitoring rather than specific application or service-level metrics. It focuses more on the data transfer between different system components rather than the delivery of requests to end-users. As such, it does not fit within the typical scope of metrics found in the "Service or Request" dashboard tiles, which are designed to give a clear view of service performance from the user perspective.
