Useful PowerShell Commands
Here are a few SCOM PowerShell commands that might come in useful. Just replace the ID here with the ID of the object you are interested in.
How to open SCOM PowerShell
Open the Operations Manager Shell: Start > Microsoft System Center > Operations Manager Shell.
To get property names for use with Scope Criteria
The Scope Criteria needs to use the SCOM internal name of the property, rather than the display name.
To get a full list you can run the following PowerShell script:
Get-SCOMClassInstance -Name "hostname.dnsdomain" | Format-List
Replacing hostname.dnsdomain with your details, for example, server1.domain.local
There is no need to qualify the property with the type name such as [Microsoft.Windows.Computer]
To query the RuleId
Get-SCOMRule -Id b603ba1e-c5ec-221e-e9e3-cf2098e7bdbd | Format-List
To query the MonitorId
Get-SCOMMonitor -Id 32c755df-94b4-5f2e-62b7-0fef16758699 | Format-List
To get details such as the DisplayName of an Object
Get-SCOMMonitoringObject -Id 6f7e3306-beeb-2996-3795-7c1eafb925b8 | Format-List
or
get-scomclass -id 2c2de865-0cd3-a6b8-51a5-3dabf7b48d4e | Format-List
If the object exists a list of information will be returned. If the object does not exist nothing will be returned.
To get details of a group
Get-SCOMGroup -Id d0720ebb-670a-3586-9d1c-a10246489de4
How to find the SCOM ID of an object or group
You can use SCOM PowerShell commands to find the SCOM ID of objects and groups as shown below, or you can very easily find the SCOM IDs in SquaredUp DS, see How to find the SCOM ID of an object or group.
Get-SCOMMonitoringObject -DisplayName "Hong Kong" | select id
This can be used for any object (or group). To list all groups and their SCOM IDs:
Get-SCOMGroup | select displayName,Id
