14.3. Configure Time-Series-Database-as-a-Service

When manually installing the Time-Series-Database-as-a-Service packages, the service's configuration file (namely, /etc/gnocchi/gnocchi.conf ) will have no settings configured. You will need to manually add and configure each setting as required.

In the [DEFAULT] section, enable logging and verbose output:
```

```

Note
The database has to be created before starting gnocchi-api

In the [keystone_authtoken] section, update the authentication parameters. For example:

[keystone_authtoken]
auth_uri = http://192.0.2.7:5000/v2.0
signing_dir = /var/cache/gnocchi
auth_host = 192.0.2.7
auth_port = 35357
auth_protocol = http
identity_uri = http://192.0.2.7:35357/
admin_user = admin
admin_password = 5179f4d3c5b1a4c51269cad2a23dbf336513efeb
admin_tenant_name = admin

[keystone_authtoken]
auth_uri = http://192.0.2.7:5000/v2.0
signing_dir = /var/cache/gnocchi
auth_host = 192.0.2.7
auth_port = 35357
auth_protocol = http
identity_uri = http://192.0.2.7:35357/
admin_user = admin

Replace the values for RESOURCE_ID, USER_ID, and PROJECT_ID with values for your deployment.

In the [storage] section, manually add the coordination_url and file_basepath and set the driver value to file:

[storage]
coordination_url = file:///var/lib/gnocchi/locks
driver = file
file_basepath = /var/lib/gnocchi

[storage]
coordination_url = file:///var/lib/gnocchi/locks
driver = file
file_basepath = /var/lib/gnocchi

Restart the gnocchi service to ensure that the change takes effect:

systemctl restart openstack-gnocchi-api.service
systemctl restart openstack-gnocchi-metricd.service
systemctl restart openstack-gnocchi-statsd.service

# systemctl restart openstack-gnocchi-api.service
# systemctl restart openstack-gnocchi-metricd.service
# systemctl restart openstack-gnocchi-statsd.service
