2. Edit the /etc/watcher/watcher.conf file and complete the following actions:

   • In the [database] section, configure database access:

     [database]
     ...
     connection = mysql+pymysql://watcher:WATCHER_DBPASS@controller/watcher?charset=utf8

   • In the [DEFAULT] section, configure the transport url for RabbitMQ message broker.

     [DEFAULT]
     ...
     control_exchange = watcher
     transport_url = rabbit://openstack:RABBIT_PASS@controller

     Replace the RABBIT_PASS with the password you chose for OpenStack user in RabbitMQ.

   • In the [keystone_authtoken] section, configure Identity service access.

     [keystone_authtoken]
     ...
     www_authenticate_uri = http://controller:5000
     auth_url = http://controller:5000
     memcached_servers = controller:11211
     auth_type = password
     project_domain_name = default
     user_domain_name = default
     project_name = service
     username = watcher
     password = WATCHER_PASS

     Replace WATCHER_PASS with the password you chose for the watcher user in the Identity service.

   • Watcher interacts with other OpenStack projects via project clients, in order to instantiate these clients, Watcher requests new session from Identity service. In the [watcher_clients_auth] section, configure the identity service access to interact with other OpenStack project clients.

     [watcher_clients_auth]
     ...
     auth_type = password
     auth_url = http://controller:5000
     username = watcher
     password = WATCHER_PASS
     project_domain_name = default
     user_domain_name = default
     project_name = service

     Replace WATCHER_PASS with the password you chose for the watcher user in the Identity service.

   • In the [api] section, configure host option.

     [api]
     ...
     host = controller

     Replace controller with the IP address of the management network interface on your controller node, typically 10.0.0.11 for the first node in the example architecture.

   • In the [oslo_messaging_notifications] section, configure the messaging driver.

     [oslo_messaging_notifications]
     ...
     driver = messagingv2

3. Populate watcher database:

   su -s /bin/sh -c "watcher-db-manage --config-file /etc/watcher/watcher.conf upgrade"
