I think it would be valuable to obtain some (optional) insight into what that cluster is actually used for. > A admin can also say that the report is allowed to be 'public' where you > can then visit (for example) https://brag.ceph.com/public/<fsid> and > show off your Ceph cluster. > > You could then add a description and we could compile top lists about > Ceph systems. > > How do people think about this? Would this be interesting? Absolutely. One challenge I can see here (in addition to users actually enabling it) is networking - I'd assume that many customers have restricted their networks, so the MGR cannot easily establish an outgoing connection without going through a proxy or before the admin has poked a hole into the firewall. This might require configuration options or corresponding documentation. > I would try to convince most of my customers to send this information > back to the project.
