OpsMgr (SCOM) - Goodbye Import-Module OperationsManager

Hello SDK!

We all suffer about the same.
Import-Module OperationsManager just takes too long - 13 seconds!

So, if you use powershell in your subscriptions in OpsMgr, to affect some customfileds with extra data, well ... it could be a problem if you have a lot of 'Impor-Modules' going on.

So, i decided to put myself working on 'how to (not) use operations manager powershell module).

First things first.
Load your SDK. (DLL's)

 [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.EnterpriseManagement.OperationsManager.Common") | Out-Null  
 [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.EnterpriseManagement.Core') | Out-Null  
 [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.EnterpriseManagement.OperationsManager') | Out-Null  
 [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.EnterpriseManagement.Runtime') | Out-Null  

Now, let's open up a connection to your MS.

 $MGConnSetting = New-Object Microsoft.EnterpriseManagement.ManagementGroupConnectionSettings($env:computername)  
 $MG = New-Object Microsoft.EnterpriseManagement.ManagementGroup($MGConnSetting)  

Now, inside this new object ($MG) you have it all, and i mean it, ALL!
Let's say you want to list a specific list of alerts based on a specific criteria.
Well, untill now you used get-scomalert cmdlet ... now you use this :

 $newTime = (Get-Date).AddHours(-24)  
 $Criteria = New-Object Microsoft.EnterpriseManagement.Monitoring.MonitoringAlertCriteria("ResolutionState = 0 AND Severity >= 1 AND TimeRaised > `'$newTime`'")  
 $MG.GetMonitoringAlerts($Criteria)  

Well, the difference ? 13 seconds!
Old-way :

 $(Get-Date)  
 Import-Module OperationsManager  
 $newTime = (Get-Date).AddHours(-24)  
 $Criteria = New-Object Microsoft.EnterpriseManagement.Monitoring.MonitoringAlertCriteria("ResolutionState = 0 AND Severity >= 1 AND TimeRaised > `'$newTime`'")  
 $Alerts = Get-SCOMAlert -Criteria $Criteria  
 $(Get-Date)

New-way :

 $(Get-Date)  
 $newTime = (Get-Date).AddHours(-24)  
 $Criteria = New-Object Microsoft.EnterpriseManagement.Monitoring.MonitoringAlertCriteria("ResolutionState = 0 AND Severity >= 1 AND TimeRaised > `'$newTime`'")  
 $Alerts = $MG.GetMonitoringAlerts($Criteria)  
 $(Get-Date)

Other examples :

 Get-SCOMClassInstance  

in our new way :

 $ClassCriteria = New-Object Microsoft.EnterpriseManagement.Configuration.MonitoringClassCriteria("DisplayName = 'Test Class'")  
 $MonitoringClass = $MG.GetMonitoringClasses($ClassCriteria)  

And related MonitoringObjects ? (Get-SCOMMonitoringObject) ?

 $MG.GetMonitoringObjects($MonitoringClass[0])
