Hello Krishkan,
SCOM provides fairly easy ways in the console to add a custom attribute onto an existing class, then populate the value of that attribute from the registry or WMI. Then you can create dynamic groups based on the value of the attribute. Under the
covers, it queries your attributes and creates the group-contains-members relationships.
There are more intricate ways to do this if you don't want to create a registry key everywhere, but they involve scripting to read your data source (database, text file, whatever) and manually create the group-contains-member relationship objects. You're
getting into the authoring console, and perhaps even XML editing to do that.
