What limitation does Dynatrace OneAgent have within Docker containers?

The limitation of Dynatrace OneAgent within Docker containers is primarily related to its ability to monitor native processes running outside the container. OneAgent is designed to provide comprehensive monitoring of applications and services within the container. However, it only has visibility into the processes and activities happening within the confines of that specific container environment.

When a container is isolated, Dynatrace OneAgent does not have access to native processes that are active on the Docker host or on other containers. This restriction is a result of the containerized nature of applications, where each container is designed to operate independently of its host and other containers. Therefore, while OneAgent can provide deep insights into the performance and health of the application running within the container, it does not extend its monitoring capabilities to processes that are operating outside of that scope.

This specific limitation helps to reinforce the principle of container isolation, where applications within containers are separated from one another and from the host system. Other options relate to scope of monitoring but do not capture this core aspect of OneAgent's operational design within Docker environments.
