I’ve seen a lot of posts on the Internet describing how you can use Orchestrator to trigger a Runbook when a condition is met. For example, Orchestrator can poll SCOM for a specific event and when it occurs it can trigger a Runbook . But what about when you want to trigger a Runbook from a different source? So today I took a look at how I could use PowerShell to trigger a Runbook. Now I have seen some posts describing how to extract the GUID of a Runbook and use that to start the Runbook. I’m not going to do that, I’m going to start a Runbook using only the name of the Runbook which I think is much easier for people to identify with a name, not a GUID. But hey, if you want to use the GUID, feel free to skip the rest of my post and head off to an example from Microsoft here: http://msdn.microsoft.com/en-us/library/hh921685.aspx.
