Hi @Anne ,
you only wan't to give a "view" on the runbook, jobs and schedules? No interaction from the users with the Orchestrator objects like "starting a runbook"?
All information should be available in via Orchestrator web service (http://youreserver:81/Orchestrator2012/Orchestrator.svc/):
https://techcommunity.microsoft.com/t5/system-center-blog/accessing-system-center-2012-orchestrator-using-the-web-service/ba-p/345014
But as far as I know there is neither a "presentation-layer" to get a "nice view" on this, nor is there a "ready to go" 3rd party solution available.
Another option might be to query the SQL database of Orchestrator. But this is even more challenging because for this the "logic" and the "presentation-layer" needs to be coded as well. I am not aware of a ready to go solution for this as well.
