What is the purpose of defining custom roles in Dynatrace?

Defining custom roles in Dynatrace serves the purpose of providing granular access to specific features. This functionality allows organizations to tailor user permissions based on the specific needs and responsibilities of individuals or teams. By creating custom roles, Dynatrace administrators can ensure that users only have access to the functionalities that are necessary for their work, which enhances security and enables better management of the monitoring environment. This level of detail in access control is crucial for organizations with diverse teams where different users may require different levels of insight or control over various aspects of the monitoring and management platform.

In contrast, the other options do not accurately reflect the core purpose of custom roles. Increasing user login frequency does not relate to access control and instead pertains to user engagement and activity. Simplifying performance monitoring is a broader feature of Dynatrace's capabilities but does not specifically address the need for defined roles. Automating user authentication is related to security but falls outside the scope of defining roles for access control; it pertains more to user management and access mechanisms rather than the specific permission structure that roles provide.
