Hello!

I want to add to My Computer Group only the Agent Watchers representing all
the discovered instances of the Custom Class I created.

If in the Discovery I put an actual FQDN of a Managed Computer the group is
populated with that Agent Watcher.

If I put
$MPElement[Name="MyApplication.Core.Windows_Local_Application.Send_Connector.Class"]/ComputerName$ it does not work but I do no receive any error.

Then I put
$Target/Host/Property[Type=”MyApplication.Core.Windows_Local_Application.Send_Connector.Class”]/ComputerName$

and after

$Target/Property[Type=”MyApplication.Core.Windows_Local_Application.Send_Connector.Class”]/ComputerName$

in place of

$MPElement[Name="MyApplication.Core.Windows_Local_Application.Send_Connector.Class"]/ComputerName$

Does not work again!

Where am I making work ?

Thank you!

Lizzie

You really had me puzzled by this one during MMS. Turns out there is a
linked list of relationships that allows this to work.

Agent Watcher IS A Health Service Watcher which CONTAINS Health Service
which (as a LocalApplication) is Hosted by Windows Computer which Hosts your
custom class (because it IS A LocalApplication)

See http://sentryboy.spaces.live.com/blog/cns!F2CBE6BAE5BB51E1!301.entry
(bottom example) for the groupcalc syntax.

Cool question. Thanks.
