logging does not work

[Na Zhu]

I follow the link http://docs.openstack.org/developer/python-openstackclient/configuration.html#logging-settings to enable openstackclient syslog, here is my cloud.yaml contents:
juno@bgpvpn:~$ cat /etc/openstack/clouds.yaml
clouds:
  devstack:
    auth:
      auth_url: http://192.168.122.102:35357
      password: blade123
      project_domain_id: default
      project_name: demo
      user_domain_id: default
      username: demo
    identity_api_version: '3'
    region_name: RegionOne
    volume_api_version: '2'
    operation_log:
      logging: TRUE
      file: /tmp/openstackclient_admin.log
      level: debug
  devstack-admin:
    auth:
      auth_url: http://192.168.122.102:35357
      password: blade123
      project_domain_id: default
      project_name: admin
      user_domain_id: default
      username: admin
    identity_api_version: '3'
    region_name: RegionOne
    volume_api_version: '2'
    operation_log:
      logging: TRUE
      file: /tmp/openstackclient_admin.log
      level: debug
  devstack-alt:
    auth:
      auth_url: http://192.168.122.102:35357
      password: blade123
      project_domain_id: default
      project_name: alt_demo
      user_domain_id: default
      username: alt_demo
    identity_api_version: '3'
    region_name: RegionOne
    volume_api_version: '2'
juno@bgpvpn:~$
Then I create a network:
juno@bgpvpn:~$ openstack --os-cloud devstack-admin network create juno

But there is no logs generated.
juno@bgpvpn:~$ cat /tmp/openstackclient_admin.log
cat: /tmp/openstackclient_admin.log: No such file or directory
juno@bgpvpn:~$

I don't see log_file or log_level set in your cloud.yaml per the documentation.
