What role is required to use a pattern for horizontal discovery?

The role required to use a pattern for horizontal discovery is specifically the discovery_admin role. This role is designed to grant permissions necessary to manage and execute discovery processes, including horizontal discovery, which involves mapping out the relationships and communications between devices within a network. The discovery_admin has elevated privileges that allow access to the features associated with configuring and running discovery patterns effectively.

Horizontal discovery patterns are crucial for identifying configurations of devices and how they interconnect, and having the appropriate role ensures that users can perform advanced functions such as creating, editing, and applying these discovery patterns without encountering permission issues. This role is tailored for users focused on managing the discovery aspect of the ServiceNow platform, making it essential for leveraging pattern-based discovery effectively.

In contrast, roles such as admin or pattern_creator may have broader or different scopes of permission that do not specifically focus on the requirements and functionalities associated with horizontal discovery. The supervisor role, while important, typically does not encompass the necessary permissions for performing advanced discovery tasks that would require in-depth technical control over the discovery processes. Thus, the discovery_admin role is the correct and most appropriate choice for this scenario.
