How can Dynatrace RUM be added for a website when you cannot install the OneAgent...

Agentless RUM enables Real User Monitoring without requiring OneAgent installation on the server. It works by injecting a JavaScript snippet into the web application, which captures user interactions and performance data directly from the browser.

This approach is useful when:

You do not have access to the server

Installing OneAgent is not possible

You still need frontend visibility

Other options do not apply:

Dynatrace Operator is for Kubernetes deployments

ActiveGate is used for routing and extending connectivity

Discovery mode still requires OneAgent installation
