Integrate radosgw into your Telemetry¶
The telemetry (and in consequence accounting) for radosgw as object-storage will not work out of the box. You need to change different parts of your OpenStack and Ceph setup to get it up and running.
Ceilometer needs additional pip packages to talk to Ceph Rados Gateway. To install it, edit the default ceilometer_pip_packages in your user_variables.yml file:
ceilometer_pip_packages: - ceilometer - ceilometermiddleware - cryptography - gnocchiclient - libvirt-python - PyMySQL - pymongo - python-memcached - tooz - warlock - requests-aws>=0.1.4 #https://github.com/openstack/ceilometer/blob/stable/pike/test-requirements.txt
You also have to configure Ceilometer to actually query radosgw. When your ceilometer isn’t configured to poll everything, add these pollsters to your polling.yml file:
- name: radosgw_pollsters interval: 1200 meters: - radosgw.containers.objects - radosgw.containers.objects.size - radosgw.objects - radosgw.objects.size - radosgw.objects.containers - radosgw.usage
Add them also to your pipeline:
- name: radosgw_source interval: 60 meters: - "rgw.objects" - "rgw.objects.size" - "rgw.objects.containers" - "rgw.api.request" - "rgw.containers.objects" - "rgw.containers.objects.size" sinks: - meter_sink
Declare Ceph Rados Gateway as object-store in your ceilometer.conf file by adding this to your user_variables.yml file:
ceilometer_ceilometer_conf_overrides: service_types: radosgw: object-store rgw_admin_credentials: access_key: XXX secret_key: XXX
The required user and credentials is created by this command:
radosgw-admin user create --uid admin --display-name "admin user" --caps "usage=read,write;metadata=read,write;users=read,write;buckets=read,write"
To get your credentials, execute:
radosgw-admin user info --uid admin | jq '.keys'
The required changes are described in the documentation of Ceilometer. This is just a sum up. In your ceph.conf add:
[client.radosgw.gateway] rgw enable usage log = true rgw usage log tick interval = 30 rgw usage log flush threshold = 1024 rgw usage max shards = 32 rgw usage max user shards = 1
