[Telemetry][TC]Telemetry status


I just want to know any other guys from the thread want to as volunteers to
take over gnocchi?

About Monasca, we discuss a lot in Shanghai, if users already use monasca,
as Lingxian mentioned ceilometer has already support publish to monasca.
but I think most of the user didn't use monasca, as a community you can
just say use monasca, but for company want to use in production, add a
component and the depends extra tools would be very very difficult, this
will need many many resources to do the things.
