Hello everyone,

I've just pulled the latest version of Devstack, installed ceilometer but when I start the services, the central agent does not manage to connect via Keystone.

I have checked the ceilometer.conf file, the admin_tenant_name, the admin_user and the admin_password are correct. Do you have an idea about the reason of this isssue?

Thanks beforehand. Best regards, Romain.
