@ Seth and Francisco:
I had the same problems and solved this issue. The tip from rory is not bad. You have to change only a little part but not in the reference section. You have to change the following in the health service section:

original:
$MPElement[Name="MicrosoftWindowsLibrary6062780!Microsoft.Windows.Computer"]$

changed:
$MPElement[Name="MicrosoftWindowsLibrary606278100!Microsoft.Windows.Computer"]$

than the Health service watcher is included in your dynamical group.

Regards, Fabian

What about False Positives? I’ve been getting alot of false positives, when really, I’m more concerned with being alerted that the Server is actually offline.

I know that the Health Service Heartbeat Failure and the Computer not Pingable work alongside each other. Is there a way to just get the “Computer Not Pingable” alert, and not the “Health service heartbeat Failure” alert?

Yes, I just used Principal Name as an example. Any dynamic group of computers will work with what I am doing here.

Can this also be done with an OU Query (instead of Principal Name)?

Great post..
1 quick question. After I create the Dynamic Group and add the Health Watcher Script script, Can I edit the Dynamic group query (to add more Servers in the future), without having to modify\export the Management Pack again?

Thanks

These are the updates I had to make to the XML to get this to work in SCOMR2 RTM: $MPElement[Name="SystemCenter!Microsoft.SystemCenter.HealthServiceWatcher"]$ $MPElement[Name="MicrosoftSystemCenterInstanceGroupLibrary6172210!Microsoft.SystemCenter.InstanceGroupContainsEntities"]$ $MPElement[Name="SystemCenter!Microsoft.SystemCenter.HealthService"]$ $MPElement[Name="MicrosoftWindowsLibrary6172210!Microsoft.Windows.Computer"]$ $Target/Id$

Hello, I have a dynamically populated group. I want to create another group that is populated from healthwatcheragent objects that are included in the first group. I can use a contained expression in xml to populate the new group, but it mirrors the first one. Regular expression Expressions entered after the Contained statement has no effect. Entering the regular expression before the contained expression fails during import of the MP. Any ideas? Thnks, BT XML that mirrors the first group to the second and regular expression has no impact. rrrrrrrr 1.0.0.6 rrrrrrrr Microsoft.SystemCenter.Library 6.0.6278.0 31bf3856ad364e35 AB_SOS_DiscoveriesAndGroups_MP 1.0.0.15 240c1aab2b6b0b06 Microsoft.SystemCenter.InstanceGroup.Library 6.0.6278.0 31bf3856ad364e35 Discovery $MPElement$ $MPElement[Name="UINameSpacec2875bcbb2564f1386b662d094f45945.Group"]$ $MPElement[Name="SC!Microsoft.SystemCenter.AgentWatcher"]$ $MPElement[Name="IGL!Microsoft.SystemCenter.InstanceGroupContainsEntities"]$ $MPElement[Name="ABSOSDiscoveriesAndGroupsMP10015!AB_SOS_BiaDeferrableServers_ComputerAndWatcherGroup"]$ $MPElement[Name="SC!Microsoft.SystemCenter.HealthServiceWatcher"]$ $MPElement[Name="SC!Microsoft.SystemCenter.HealthServiceWatcher"]/HealthServiceName$ MatchesRegularExpression (?i:^DEV*) rrrrrrrr aaatest Populate aaatest This discovery rule populates the group 'aaatest'

I tried the above and get the following error message when trying to import. I also tried deleted the original mp and reimporting:

Any ideas?

CriticalServers could not be imported.

If any management packs in the Import list are dependent on this management pack, the installation of the dependent management packs will fail.

The requested management pack was invalid. See inner exception for details.
Parameter name: managementPack
