The New Real User Monitoring (RUM) Experience provides deep visibility into how end users interact with the frontends of your applications. The RUM models are organized into the following subcategories:

The following reference contains a list of fields that have a well-defined semantic meaning in Dynatrace RUM. The fields are organized in namespaces that are separated with dots.
