Description of problem:

When using swift as a backend for gnocchi, there is a default configuration which is placed by puppet inside /etc/swift/proxy-server.conf, this configuration has a typo for the project_name parameter.


Below is the snippet of the configuration put by puppet.

+++
[filter:ceilometer]
paste.filter_factory = ceilometermiddleware.swift:filter_factory

url = rabbit://guest:tXxPT6rQMWJdpEhpwQk7B9rsx.125.60:5672,guest:tXxPT6rQMWJdpEhpwQk7B9rsx.125.56:5672,guest:tXxPT6rQMWJdpEhpwQk7B9rsx.125.53:5672//


ignore_projects = ["service"]


auth_uri = http://172.168.125.51:5000/v2.0


auth_url = http://172.168.125.51:5000


auth_type = password


project_name = services << project_name is set to services however the correct name should be 'service'


project_domain_name = Default


user_domain_name = Default


username = swift


password = jf7AF62ZCwau4hMJAX8r4YwQm
+++


Now by default ceilometer is present in the [pipeline:main] section:

+++
[pipeline:main]
pipeline = catch_errors healthcheck proxy-logging cache ratelimit bulk tempurl formpost authtoken keystone staticweb versioned_writes proxy-logging proxy-server
+++

Once you enable ceilometer in the [pipeline:main] section and then restart the openstack-swift-proxy service it fails with the below error:

+++
[pipeline:main]
pipeline = catch_errors healthcheck proxy-logging cache ratelimit bulk tempurl formpost authtoken keystone staticweb versioned_writes ceilometer proxy-logging proxy-server

The simple fix is to correct the project_name parameter in the [filter:ceilometer] section and set it to 'service'

after doing that , restarting the openstack-swift-proxy service fixes the issue:

The rest of the configuration bits appear to be in place:

+---------------+------------+---------+

[filter:keystone]
use = egg:swift#keystoneauth
operator_roles = admin, swiftoperator, ResellerAdmin  << the operator_roles parameter also appears to be set fine.

and [filter:ceilometer] section has the correct configuration for rabbitmq in place

How reproducible:
Always with the default configuration in place. Just enable ceilometer in the main pipeline and restart the openstack-swift-proxy service
