Mitaka ceilometer doesn't work with keystone v3

[Brad Marshall]

I've got a cloud deployed with Trusty and mitaka (from the cloud archives), using keystone v3.

I'm having troubles with mitaka ceilometer not working by default with keystone v3. As deployed, I get:

{{{
$ ceilometer meter-list
Service Unavailable (HTTP 503) (Request-ID: req-21d65a42-1254-4bc9-9d14-2ed50a6ddbed)
}}}

After some searching around and hacking up the ceilometer.conf, I got it working. The changes required in {{{/etc/ceilometer/ceilometer.conf}}} were:

{{{
[service_credentials]
os_auth_url = http://10.28.3.240:5000/v3
os_endpoint_type = internalURL
os_region_name = my-region

[keystone_authtoken]
user_domain_name = Default
project_domain_name = Default
}}}

That is, I added os_endpoint_type and os_region_name to the service_credentials set, and fixed os_auth_url to be using /v3 instead of a hard coded /v2.0. Also I added user_domain_name and project_domain_name in keystone_authtoken.

Note I'm not sure if all of those are required, specifically os_endpoint_type I wasn't 100% sure.

Once I added those and restarted the appropriate services, I could get output from {{{ceilometer meter-list}}}.

Ceilometer charm is rev 141, keystone is rev 260.

    Fix Keystone v3 integration for Mitaka+

    The ceilometer.conf was using its defining its own keystone-authtoken
    section which lacks Keystone v3 support rather than using the shared
    template fragment from charmhelpers.

Two review links, I don't know why #378489 doesn't display here, so pasted them as below:

I pushed a few updates to the proposed review to ceilometer-agent as I tripped over a related issue to this in testing for newton.

    Add keystone v3 support for service_credentials

    service_credentials is used for the keystoneauth1.session.Session
    class to bring a unified interface to the various openstack
    clients that share common authentication and request parameters
    between a variety of services. This patch will add keystone v3
    support for service_credentials in ceilometer.
