DT_CUSTOM_PROP is primarily used for which purpose in Dynatrace?

The primary purpose of DT_CUSTOM_PROP in Dynatrace is to create custom process group metadata. This feature allows users to add specific properties to process groups, enabling better classification and organization of monitored entities within the Dynatrace environment. By defining these custom properties, users can tailor the monitoring experience to their unique application architecture and operational needs, allowing for enhanced filtering, reporting, and analysis within the Dynatrace platform.

Creating custom metadata aids in robust observability practices, ensuring that stakeholders can derive meaningful insights from the data being collected and analyzed. This is particularly useful for environments where applications or services may have distinct characteristics that merit differentiated tracking or analysis.

While the other choices mention relevant functionalities within Dynatrace, they do not align with the core usage of DT_CUSTOM_PROP. Custom user actions, tagging user sessions, and monitoring application performance are handled through different features and capabilities within Dynatrace, focusing on various aspects of performance monitoring and user experience rather than the details encompassed by custom process group metadata.
