Comment 5 for bug 1523881

For anyone still wondering how to do this, I think I figured it out. Take a look at how the cloudkitty devstack plugin config (https://github.com/openstack/cloudkitty/blob/master/devstack/plugin.sh) looks like, and use that in your config! It needs an authinfos section that other sections then reference, like this:

[authinfos]
auth_type = v2password
auth_url = $keystone_url:5000/v2.0/
username = cloudkitty
password = $service_password
tenant_name = $service_tenant_name (probably 'services')
region_name = $region

[keystone_fetcher]
auth_section = authinfos

[ceilometer_collector]
auth_section = authinfos

[collect]
collector = ceilometer
services = $services_to_collect

Hope that helps!
