Verifying infrastructure operation

Verify the database cluster and Kibana web interface operation.

Procedure 7.1. Verifying the database cluster

1. Determine the Galera container name:

   # lxc-ls | grep galera
   infra1_galera_container-4ed0d84a

2. Access the Galera container:

   # lxc-attach -n infra1_galera_container-4ed0d84a

3. Run the MariaDB client, show cluster status, and exit the client:

   # mysql -u root -p
   MariaDB> show status like 'wsrep_cluster%';
   +--------------------------+--------------------------------------+
   | Variable_name            | Value                                |
   +--------------------------+--------------------------------------+
   | wsrep_cluster_conf_id    | 3                                    |
   | wsrep_cluster_size       | 3                                    |
   | wsrep_cluster_state_uuid | bbe3f0f6-3a88-11e4-bd8f-f7c9e138dd07 |
   | wsrep_cluster_status     | Primary                              |
   +--------------------------+--------------------------------------+
   MariaDB> exit

   The wsrep_cluster_size field should indicate the number of nodes in the cluster and the wsrep_cluster_status field should indicate primary.

 

Procedure 7.2. Verifying the Kibana web interface

1. With a web browser, access the Kibana web interface using the external load balancer IP address defined by the external_lb_vip_address option in the /etc/openstack_deploy/openstack_user_config.yml file. The Kibana web interface uses HTTPS on port 8443.
2. Authenticate using the username kibana and password defined by the kibana_password option in the /etc/openstack_deploy/user_variables.yml file.
