Description Dan Yocum 2015-12-17 16:09:21 UTC 
Description of problem:

There should be a short section on how to access and check galera to verify functionality (i.e., replication).
Comment 2 Dan Yocum 2015-12-17 17:26:15 UTC 
The following commands, gleened from this article should be sufficient to determine the health of the galera cluster - http://galeracluster.com/documentation-webpages/monitoringthecluster.html

     mysql -B -e "SHOW GLOBAL STATUS LIKE 'wsrep_cluster_state_uuid';"
     mysql -B -e "SHOW GLOBAL STATUS LIKE 'wsrep_cluster_conf_id';"
     mysql -B -e "SHOW GLOBAL STATUS LIKE 'wsrep_cluster_size';"
     mysql -B -e "SHOW GLOBAL STATUS LIKE 'wsrep_cluster_status';"
     mysql -B -e "SHOW GLOBAL STATUS LIKE 'wsrep_%';"
     mysql -B -e "SHOW GLOBAL STATUS LIKE 'wsrep_ready';
     mysql -B -e "SHOW GLOBAL STATUS LIKE 'wsrep_ready';"
     mysql -B -e "SHOW GLOBAL STATUS LIKE 'wsrep_connected';"
     mysql -B -e "SHOW GLOBAL STATUS LIKE 'wsrep_local_state_comment';"
     mysql -B -e "SHOW STATUS LIKE 'wsrep_local_recv_queue_avg';"
     mysql -B -e "SHOW STATUS LIKE 'wsrep_flow_control_paused';"
     mysql -B -e "SHOW STATUS LIKE 'wsrep_cert_deps_distance';"

These should run on all controller nodes and the values compared.
