What is needed to use the OneAgent metric API for Micrometer metrics ingestion?

To use the OneAgent metric API for Micrometer metrics ingestion, having the OneAgent installed on the monitored host is essential. OneAgent acts as an intelligent monitoring agent that collects, processes, and sends telemetry data from the monitored host to the Dynatrace platform. Without the installation of OneAgent on the host machine, there would be no mechanism to gather the Micrometer metrics, as OneAgent is the component that interfaces with the application and captures real-time performance data.

The other aspects related to the metric API, such as connecting to a satellite server or needing predefined metrics, do not directly relate to the fundamental requirement for the OneAgent's presence on the host. Similarly, while compensation mechanisms may be relevant in certain contexts of monitoring, they are not a prerequisite for using the OneAgent metric API specifically for Micrometer. Thus, the key aspect that enables the functionality and integration of the metric API is indeed the presence of OneAgent on the monitored host.
