Azure role-based access control permissions required to use Network Watcher capabilities
Azure role-based access control (Azure RBAC) enables you to assign only the specific actions to members of your organization that they require to complete their assigned responsibilities. To use Azure Network Watcher capabilities, the account you log into Azure with, must be assigned to the Owner, Contributor, or Network contributor built-in roles, or assigned to a custom role that is assigned the actions listed for each Network Watcher capability in the sections that follow. To learn how to check roles assigned to a user for a subscription, see List Azure role assignments using the Azure portal. If you can't see the role assignments, contact the respective subscription admin. To learn more about Network Watcher's capabilities, see What is Network Watcher?
