Which environment variable is used for defining custom process group metadata?

The choice of DT_CUSTOM_PROP as the environment variable for defining custom process group metadata is accurate because this variable allows users to specify property values that enhance the information associated with process groups in Dynatrace.

When configuring Dynatrace, metadata is crucial as it provides context about the processes running in your environment. By utilizing DT_CUSTOM_PROP, you can define key-value pairs that reflect specific characteristics or classifications relevant to your applications. This can include information such as the environment type, owner, application name, or any other relevant custom tags. Collecting this information helps in organizing and managing your monitored entities more effectively within the Dynatrace platform.

Other options serve distinct purposes and do not fit the context of defining process group metadata. For instance, DT_CUSTOM_TAGS is focused on tagging entities dynamically, and DT_META_PROP might suggest a connection with metadata but does not specifically target custom properties for process groups. DT_ENV_VAR is a general variable for environment settings, again not tailored for custom process group metadata. Hence, DT_CUSTOM_PROP stands out as the dedicated option for this use case.
