In System Center 2012 Configuration Manager, you can read user-defined status messages, on the site server, by querying the SMS Provider.

To read a user-defined status messages

  1. Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.

  2. Query the provider for the SMS_StatusMessage instances you want. As part of the query get the insertion string values from SMS_SMS_StatMsgInStrings and the attribute value from SMS_StatMsgAttributes.

Example

The following example reads error message status messages for the sample created in How to Report User-Defined Status Messages. Make sure the MyPackageID and MyApplication values in the query match in both samples.

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

Visual Basic Script  Copy Code 
Sub ReadErrorStatusMesage(connection)

	Dim queryWQL
	Dim message
	Dim messageSet
	Dim statusMessage
	Dim insertionString
	Dim attributes

	queryWQL = "SELECT b.Component, b.MachineName, b.MessageType, b.MessageID, " & _
			"	 c.InsStrValue, d.AttributeValue " & _
			"FROM SMS_StatusMessage b " & _
			"	 JOIN SMS_StatMsgInsStrings c ON b.RecordID = c.RecordID " & _
			"	 JOIN SMS_StatMsgAttributes d ON c.RecordID = d.RecordID " & _
			"WHERE b.Component = 'MyApplication' " & _
			"AND   d.AttributeID = 400 " & _
			"AND   d.AttributeValue = 'MyPackageID' "

	Set messageSet = connection.ExecQuery(queryWQL)

	For Each message in messageSet
	
		' Get the message objects.
		statusMessage = message.Properties_.Item("b")
		insertionString = message.Properties_.Item("c")
		attributes = message.Properties_.Item("d")
	
		' Display the message details.
		WScript.Echo "Message: " + insertionString.Properties_.Item("insstrvalue")
		WScript.Echo "Component: " + statusMessage.Properties_.Item("Component")
		WScript.Echo "Machine: " + statusMessage.Properties_.Item("MachineName")
		WScript.Echo "MessageID: " + Cstr(statusMessage.Properties_.Item("MessageID"))
		WScript.Echo attributes.Properties_.Item("attributevalue")
		WScript.Echo
	 
	Next					

 End Sub

public void ReadErrorStatusMessage(WqlConnectionManager connection)

		IResultObject query = connection.QueryProcessor.ExecuteQuery(queryWQL);
		foreach (IResultObject o in query)
		{

			ManagementBaseObject  statusMessage = (ManagementBaseObject)o["b"].ObjectValue;
			ManagementBaseObject insertionString = (ManagementBaseObject)o["c"].ObjectValue;
			ManagementBaseObject attributes = (ManagementBaseObject)o["d"].ObjectValue;

			Console.WriteLine("Message: " + insertionString["insstrvalue"]);
			Console.WriteLine("Component: " + statusMessage["Component"]);
			Console.WriteLine("Machine: " + statusMessage["MachineName"]);
			Console.WriteLine("MessageID: " + statusMessage["MessageID"]);
			Console.WriteLine(attributes["attributevalue"]);
			Console.WriteLine();
	}
}
	catch (SmsException ex)
	{
		Console.WriteLine("Failed to read status message: ", ex.Message);
		throw;
}
