Gets or sets the identifier for the instance of the monitoring class that is the context for the override. The context instance can be a monitoring object or a group. If this property is null, then the context for the override is a class rather than a class instance, in which case the context can be found in the Context property. Namespace: Microsoft.EnterpriseManagement.Configuration
Assembly: Microsoft.EnterpriseManagement.OperationsManager (in microsoft.enterprisemanagement.operationsmanager.dll)

Usage

Visual Basic 
Dim instance As ManagementPackOverride
Dim value As Nullable(Of Guid)

value = instance.ContextInstance

instance.ContextInstance = value

Syntax

Visual Basic 
Public Property ContextInstance As Nullable(Of Guid)
C# 
public Nullable<Guid> ContextInstance { get; set; }
C++ 
public:
property Nullable<Guid> ContextInstance {
		Nullable<Guid> get ();
		void set (Nullable<Guid> value);
}
J# 
/** @property */
public Nullable<Guid> get_ContextInstance ()

/** @property */
public void set_ContextInstance (Nullable<Guid> value)
JScript 
public function get ContextInstance () : Nullable<Guid>

public function set ContextInstance (value : Nullable<Guid>)

Property Value

A null or GUID value.

Example

The following code example shows how to get the PartialMonitoringObject object that is the context instance for the override.

C#  Copy Code 
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.EnterpriseManagement.Configuration;
using Microsoft.EnterpriseManagement;
using System.Collections.ObjectModel;
using Microsoft.EnterpriseManagement.Common;
using Microsoft.EnterpriseManagement.Monitoring;

namespace SDKSamples
{
	class Program
	{
		static void Main(string[] args)
		{
			ManagementGroup mg = new ManagementGroup("localhost");
			ReadOnlyCollection<ManagementPackOverride> overrides = mg.GetMonitoringOverrides();

			foreach (ManagementPackOverride mpOverride in overrides)
			{
				Console.WriteLine("Override name: " + mpOverride.Name);
				if (mpOverride.ContextInstance == null)
				{
					// The context is a class.
					try
					{
						MonitoringClass mc = mg.GetMonitoringClass(mpOverride.Context.Id);
						Console.WriteLine("	Override context (class): " + mc.Name);

				}
					catch (ObjectNotFoundException)
					{
						Console.WriteLine("	Override context: Not Found.");
				}
			}
				else
				{
					// The context is a monitoring object or group.
					PartialMonitoringObject partialObject =
						mg.GetPartialMonitoringObject(mpOverride.ContextInstance.Value);

					Console.WriteLine("	Override context (instance): " + partialObject.Name);
			}
		}
	}
}
}

Remarks

Pass the identifier returned from this property into the GetPartialMonitoringObject or GetMonitoringObject method to retrieve the context instance monitoring object.
