Retrieving the network devices being monitored by OM2012 using PowerShell

  • Article

Today I got a question from a co-worker about retrieving the monitored network devices by OM2012 using PowerShell. For Agents it’s pretty simple, you just use the Get-SCOMAgent Cmdlet and you have a nice overview of the Agents being monitored by OM2012.

But which Cmdlet should you use to get an overview of the monitored network devices? There is no Get-SCOMNetworkDevice Cmdlet.

To retrieve the network devices being monitored by OM2012, you need the following Cmdlets Get-SCOMClass and Get-SCOMClassInstance.

 Get-SCOMClass -DisplayName "Network Device" | Get-SCOMClassInstance

If you want to retrieve some more info about the network devices being monitored you can use the following PowerShell commands.

 $SCOMNetworkDevices = Get-SCOMClass -DisplayName "Network Device" | Get-SCOMClassInstance

$SCOMNetworkDevices | Format-List *

$SCOMNetworkDevices | select ManagementGroup, DisplayName, @{Label="AccessMode";Expression={$_.'[System.NetworkManagement.Node].AccessMode'}},
                         @{Label="Certification";Expression={$_.'[System.NetworkManagement.Node].Certification'}}, 
                         @{Label="SystemObjectId";Expression={$_.'[System.NetworkManagement.Node].SystemObjectId'}}
