13.5. Set Time-Series-Database-as-a-Service as the Backend for Telemetry Service
Telemetry service, by default only saves metering data in a database. To allow Telemetry to send metering data to other systems in addition to the database, multiple dispatchers can be developed and enabled by modifying the Telemetry configuration file. The
gnocchi dispatcher posts the meters onto TDSaaS backend.
For the
gnocchi dispatcher, add the following configuration settings to the /etc/ceilometer/ceilometer.conf file:
[DEFAULT] dispatcher = gnocchi [dispatcher_gnocchi] filter_project = gnocchi_swift filter_service_activity = True archive_policy = low url = http://localhost:8041
The
url in the above configuration is a TDSaaS endpoint URL and depends on your deployment.
Note
If the
gnocchi dispatcher is enabled, Ceilometer API calls will return a 410, with an empty result. The TDSaaS API should be used instead to access the data.
Restart the
gnocchi service to ensure that the change takes effect:
#systemctl restart openstack-ceilometer-api.service
