How are custom metrics retained in Dynatrace?

Custom metrics in Dynatrace are retained according to the DDU (Davis Data Unit) usage plan. This plan defines how long custom metrics are stored based on the volume of data that an organization has agreed to collect and process. Dynatrace applies usage limits according to the subscription agreement, which includes the retention period for historical data. This means that the extent to which custom metrics are retained directly correlates to the DDU usage plan, ensuring that organizations can manage their data retention efficiently while also optimizing performance and resource usage.

Other options may suggest various retention mechanisms, but they do not accurately depict how Dynatrace manages and retains custom metrics in alignment with DDU usage specifics. Thus, understanding the role of the DDU in data retention is crucial for effectively utilizing custom metrics within Dynatrace.
