Which scenario suggests the use of the manual approach for Real User Monitoring?

The scenario indicating a preference for the manual approach in Real User Monitoring arises when code access is available but access to the host is not. In this situation, implementing Real User Monitoring manually provides the necessary flexibility and control over the code, enabling the appropriate integration of monitoring scripts or libraries directly within the application. This can help ensure that the monitoring captures the required metrics relevant to user experience and application performance, even without direct access to the host environment.

This manual implementation can also facilitate customization specific to the application’s architecture and usage patterns, tailoring the monitoring tools according to the needs of the application. Thus, having code access allows for the necessary configurations and adjustments to be made efficiently, capturing relevant data without needing host-level access.

When other factors like the simplicity of the domain structure or heavy traffic are considered, they may influence monitoring strategies but do not directly necessitate a manual approach. Similarly, having access to the host is not a condition that would require the manual intervention that comes with code access, but it provides an easier, potentially less intrusive technique for deploying Real User Monitoring solutions.
