Description Julien Danjou 2016-08-12 15:59:20 UTC 
Once installed via OSPd, Ceilometer collector should be configured to rely on Gnocchi to store its gathered metrics.

All tests are passing (except the upgrade tests that I can't run)

I have discovered two bugs, that I have workarounded to be able to run the tests procedure:

https://bugzilla.redhat.com/show_bug.cgi?id=1387122 (statsd usable by default, the firewall block it)
https://bugzilla.redhat.com/show_bug.cgi?id=1387121 (not critical at all, just logging issue)
Comment 8 Mehdi ABAAKOUK 2016-11-04 14:12:28 UTC 
Upgrade test done and verified
Comment 11 Julien Danjou 2016-11-14 09:35:57 UTC 
Hi Lucy,

Definitely. I don't know what the doc says exactly today, but this do change things a bit. The old Ceilometer API and therefore its associated "ceilometer <foobar>" (e.g. ceilometer sample-list or meter-list) commands won't work anymore by default as Ceilometer won't store any data itself.

Users should use the Gnocchi API instead and the "gnocchi <foobar>" command line tool, which will be fully available instead.

Let me know if you need more information or if you want me to review anything.
