Description Arx Cruz 2016-02-09 06:31:18 EST
Description of problem:
When adding ceilometer to the pipeline, swift-proxy cannot start as it cannot read /etc/ceilometer/ceilometer.conf or create the swift-proxy log file in /var/log/ceilometer 

usermod -g ceilometer -G swift swift

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. Install packstack
2. Configure swift-proxy editing /etc/swift/proxy-server.conf
3. Add ceilometer in the pipeline before proxy-server
4. Add the following filter:

use = egg:ceilometer#swift
5. Restart openstack-swift-proxy service

Actual results:
openstack-swift-proxy service fails

Expected results:
openstack-swift-proxy service start successfully

Additional info:
If there's no access to /var/log/ceilometer, this is the error that happens:

Traceback (most recent call last):

    sys.exit(run_wsgi(conf_file, 'proxy-server', default_port=8080, **options))

    stream = open(self.baseFilename, self.mode)
IOError: [Errno 13] Permission denied: '/var/log/ceilometer/swift-proxy-server.log'

Also swift need to have access to /etc/ceilometer/ceilometer.conf

As workaround to make it works, I change the permissions on /var/log/ceilometer  to group rw, /etc/ceilometer to group rwx and add swift user in ceilometer group with the command:

usermod -g ceilometer -G swift swift

After that, the service starts successfully.

Notice that this issue was already fixed upstream, launchpad bug id attached.
