SCOrch (Orchestrator) - Runbook Monitor

I've got a bunch of Orchestrator Runbooks that need to be always running, and sometimes (reboots, or other reasons) those Runbooks maybe stopped.

So i've made this Powershell script to put on schedule tasks or somewhere else (perhaps a Operations Manager monitor - i'll do it later! :) )

The script :

<#
If for some reason you get the following PS error :
    Exception calling "GetResponse" with "0" argument(s): "The remote server returned an error: (400) Bad Request."

    Please log-in into Orchestrator Database and run :

    TRUNCATE TABLE [Microsoft.SystemCenter.Orchestrator.Internal].AuthorizationCache;
    EXEC [Microsoft.SystemCenter.Orchestrator.Maintenance].EnqueueRecurrentTask ‘ClearAuthorizationCache’

#>
 'Starting monitoring ... ' >> C:\Powershell\Log\RunbookManager.log  

 # Runbook names here :)  
 $OpsMgrRunbooks =@('1-Runbook','2-Runbook','3-Any-other-Runbook-Name')  
 $user = 'your_orchestrator_user'  
 $pass = ConvertTo-SecureString 'your_password' -AsPlainText -Force  
 $creds = New-Object System.Management.Automation.PsCredential($user,$pass)  
 foreach ($runbook in $OpsMgrRunbooks) {  
   $url = "http://YOUR_ORCHESTRATOR_SERVER:81/Orchestrator2012/Orchestrator.svc/Jobs()?`$expand=Runbook&`$filter=(Runbook/Name eq '$runbook')&`$select=Runbook/Name,Status"

   }  
   Else { "Runbook $runbook | $bookid - Already running" >> C:\Powershell\Log\RunbookManager.log }  
 }  

You'll get the following output :

Hope you find it useful :)
