What is the scope of this integration? Are you looking to mirror all metrics Orion receives in HPE's Operation Bridge Reporter? This would be a job for the Orion SDK but I would anticipate this would take a fair amount of time to achieve.
Perhaps you could look at turning this on it's head, and include important information from OBR in a tab including a custom HTML resource on an Orion NOC view? That way you would have all your important metrics from OBR, but also access to ALL of Orion's resources
