Ceilosca is a combination of Ceilometer and Monasca. In Ceilosca data collected using the Ceilometer Agents (Notification Agent, Central/Compute Agent) is sent to the Monasca API and retrieved back using the Ceilometer V2 API for backwards compatibility.
Note that the Telemetry project has deprecated the Ceilometer v2 API starting in Newton and the API has been removed in the Queens release of Ceilometer. Ceilosca continues to support the Ceilometer v2 API through Pike, though users are encouraged to switch to using the Monasca API going forward. Data gathered through the Ceilometer agents will still continue to be published and stored in Monasca.

- Makes use of existing Ceilometer sample gathering functionality through OpenStack services
- Leverages the Monasca monitoring setup, thus reducing overall complexity in cloud deployment
- Integrated with devstack deployment so you can try it out
Ceilosca has two major components:
- A publisher component that takes samples from the Ceilometer Agent and publishes them to the Monasca API.
- A storage driver component that works with the Ceilometer V2 API to use the Monasca API to retrieve stored samples.
Additionally, the Ceilosca project includes testing resources and a Devstack plugin to allow deployment.
Deployment and Troubleshooting
For information on how to deploy Ceilosca, see the monasca-ceilometer/README.md and monasca-ceilometer/devstack/README.md. In brief, Ceilosca may be overlaid on a devstack deployment which has Ceilometer and Monasca services, or you may use the provided Vagrant file to deploy a complete Ceilosca devstack, or you may use the examples and directions provided to include Ceilosca in your own deployment mechanism.
Troubleshooting - Devstack deployment
- Look in /opt/stack/logs/ceilometer.log for errors
- The Ceilometer command line client needs to have the correct environment variables set. If you have trouble connecting to Monasca, try using the default password from Monasca.
* export OS_PROJECT_NAME=service * export OS_IDENTITY_API_VERSION=3 * export OS_PASSWORD=<password set in local.conf as SERVICE_PASSWORD> * export OS_AUTH_URL=http://<fill in your Keystone ip>/identity/v3/ * export OS_USERNAME=ceilometer * export OS_TENANT_NAME=service
- Check items in the Common deployment section below
Troubleshooting - Common deployment
- Check the Ceilometer services are running
- Check /etc/ceilometer/pipeline.yaml has a proper publishers: -monasca:// entry
- Check /etc/ceilometer/pipeline.yaml has meters defined that match what you want to gather
- Check that /etc/ceilometer/ceilometer.conf has an entry in [database] for metering_connection that specifies a monasca://http: address that points to your monasca instance
- Look in /var/log/ceilometer.log or /opt/stack/logs/ceilometer.log for errors
- Look in /var/log/monasca/api/monasca-api.log for connection issues from ceilometer
