Hello @shivraj lokhande ,
Yes, for deployments using Azure Active Directory, the management server requires communication with Microsoft Azure. In this case, the workstation with the Operations Manager console that will be used to configure Azure Stack Hub monitoring must have a connection to the Internet during the initial configuration process.
Before running the management pack, you must also manually ensure that the following prerequisites are met:
• You must have 2002 or later version of the Azure Stack Hub installed.
• You must have an Operations Manager 2012 R2 or later environment installed external to Azure Stack Hub.
For more details, please download the guide for System Center Management Pack for Microsoft Azure Stack Hub
