Telemetry uses a combination of polling and notifications to collect Object Storage meters.
Your environment must include the Object Storage service.
The Telemetry service requires access to the Object Storage service using the ResellerAdmin role. Perform these steps on the controller node.
Source the admin credentials to gain access to admin-only CLI commands.
$ . admin-openrc
Create the ResellerAdmin role:
$ openstack role create ResellerAdmin
+-----------+----------------------------------+
| Field | Value |
+-----------+----------------------------------+
| domain_id | None |
| id | 462fa46c13fd4798a95a3bfbe27b5e54 |
| name | ResellerAdmin |
+-----------+----------------------------------+
Add the ResellerAdmin role to the ceilometer user:
$ openstack role add --project service --user ceilometer ResellerAdmin
This command provides no output.
Install the packages:
# apt-get install python-ceilometermiddleware
Perform these steps on the controller and any other nodes that run the Object Storage proxy service.
Edit the /etc/swift/proxy-server.conf file and complete the following actions:
In the [filter:keystoneauth] section, add the ResellerAdmin role:
[filter:keystoneauth]
...
operator_roles = admin, user, ResellerAdmin
In the [pipeline:main] section, add ceilometer:
[pipeline:main]
pipeline = catch_errors gatekeeper healthcheck proxy-logging cache container_sync bulk ratelimit authtoken keystoneauth container-quotas account-quotas slo dlo versioned_writes proxy-logging ceilometer proxy-server
In the [filter:ceilometer] section, configure notifications:
[filter:ceilometer]
paste.filter_factory = ceilometermiddleware.swift:filter_factory
...
control_exchange = swift
url = rabbit://openstack:RABBIT_PASS@controller:5672/
driver = messagingv2
topic = notifications
log_level = WARN
Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.
Restart the Object Storage proxy service:
# service swift-proxy restart
