Which user type cannot install Dynatrace OneAgent?

The user type that cannot install Dynatrace OneAgent is the monitoring viewer. This role is primarily designed for individuals who need access to view monitoring data and insights provided by Dynatrace but do not have the necessary permissions or responsibilities for managing resources directly.

In contrast, the other user types mentioned have specific levels of access and permissions that enable them to perform installation and deployment tasks. The confidential data admin and deployment admin roles typically have the necessary administrative privileges to carry out installations and configure monitoring agents. The account manager may also have certain privileges allowing for the management of deployments. Hence, the monitoring viewer's restricted access is the reason they cannot install Dynatrace OneAgent.
