How to generate a list of agents that are multi-homed via the Microsoft Operations Manager console

If you ever find yourself in a situation where you need a list of all of the multi-homed agents in your Operations Manager environment, here’s a quick and easy way to do it.

In this example, let’s say that I have agents that are reporting to a management group named test_scom and can get failover to scom1. What I need is a way to get a list of multi-homed computers for the management group named test_scom.

Solution

If we take a look on the agent side, on a multi-homed client we will see the registry keys that looks something like this:

So the registry keys for scom1 and test_scom show that my agent is multi-homed to the management group. Once we know that, we can easily go to the console and get a list of clients with similar attributes. Here are the steps:

1. From your Operations Manager console, go to Authoring. Select Management pack objects and then right-click on Attributes.

2. Create an attribute named “Multihomed” and for Discovery Type select Registry.

3. For Target we’ll select Windows Computer_Extended.

4. Select the management pack and click Next.

5. Under Key or Value Type, select Key.

6. For the path, specify HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Agent Management Groups\SCOM1.

7. Make sure Attribute Type is set to Check if exists and click Finish.

8. Now that we’re done with the attribute, let’s go to Monitoring and then Discovered Inventory.

9. Change the target type to “Windows_Computer_Extended” and you’ll see a list similar to the following:

But this list is showing all the agents. No problem, scroll towards the right and on the right-hand side check the value of the attribute multihomed. This value will appear as true and should look something like this:

That’s all there is to it!
