Get Alert of dependent Groups

Question

Hello!

I have a Serviceobject with some dependent Groups.

The Monitors of the Instances wich are members of the groups are creating Alerts.

Between the Service-Object and Group-Object their are relationships and Dependence Monitors.

I want to create a Powershell-Skript that is reading the unhelathy Monitor(s) and write-out the alert.

for example. The Monitor of MyInstance1 is Error and an alert is created. Because of dependency the Service-Object "MyService" is also unhealthy. Now I want to start a script that find out the unhealty monitor with the alert-message.

How can I do this?

My dependency-Monitors don't create an alert.

There probably is a way to do it, but I would rather try a slightly different approach : what you're interested in are the actual alerts and the health of the objects they're coming from, right?
Since the groups are not creating alerts anyway, let's just fetch the actual alerts and display them with their originating object name and health state :

Get-SCOMClass -displayname "Certificate Services" | Get-SCOMClassInstance | %{$_.GetRelatedMonitoringObjects()} | %{$_.GetMonitoringRelationshipObjects()} | %{$_.TargetMonitoringObject} | Get-SCOMAlert | where {$_.resolutionstate -ne 255} | select MonitoringObjectDisplayName,MonitoringObjectHealthState,Name

It's fairly easy to achieve, you'll find two different code examples here : https://social.technet.microsoft.com/Forums/systemcenter/en-US/6414cc9d-ca36-46fc-9b3d-48b8f8b08d8c/psh-list-all-alerts-of-a-certain-distributed-application?forum=operationsmanagergeneral

Hello
Many thanks for Info.

I have tested it. But one thing I want to filter:

Get-SCOMClass -displayname "MyService" | Get-SCOMClassInstance | %{$_.GetRelatedMonitoringObjects()} | %{$_.GetMonitoringRelationshipObjects()} | %{$_.TargetMonitoringObject}  
  
HealthState     InMaintenanceMode  DisplayName                                                                                             
-----------     -----------------  -----------    
Error               False          MyInstance1  
Error               False          MyInstance2  
Uninitialized       False          not available        
Error               False          MyGroup  

The Object with DisplayName "MyGroup" I don't want in selection.
I have append next pipe "| Where-object {$_.Name -ne $null}". I don't know if this is correct.

If you look at the Object-Information you can see, that at the group-object no name and no path is listed.

Or is their a other possibility with PS-Command?

Hey,

I would filter, based on the DisplayName, not on the property value, being empty…

| Where-object {$_.DisplayName -ne "MyGrouDisplayName"}

Otherwise you can potentially filter out other objects, which have no value in the 'Name' property.

If the DisplayName is correct, you can simply use it to do the exclusion :
Get-SCOMClass -displayname "MyService" | Get-SCOMClassInstance | %{$.GetRelatedMonitoringObjects()} | ? {$.DisplayName -ne 'MyGroup Display Name'} | %{$.GetMonitoringRelationshipObjects()} | %{$.TargetMonitoringObject}
