MIM Hybrid Reporting questions

Hi,

Looking at this article: https://technet.microsoft.com/en-us/library/mt148517(v=ws.11).aspx, it talks about installing a Reporting Agent on MIM, got a few questions:

1. Which MIM server do you install the Reporting Agent on? MIM Sync or MIM Service?
2. Must all the MIM data go to Azure? Is there a way to send it to another target system, like for example a Private Cloud SIEM system? What options do we really have?
   
3. The article also mentions creating custom reports in Azure - where is a guide on how to create these custom reports?
4. Is the actual Metaverse data (i.e. user metadata) replicated by this Reporting Agent?
5. Can we also report on Groups?
6. The FIM/MIM reporting solution based on System Centre shipped with 7 reports - are these available in Azure?

Thank you,

SK
