I am using the Community Version for over a year. Now I get the message: "Your cluster list is empty!"

The following update was installes on the clustercontrol server:

Jan 16 11:11:37 Updated: MariaDB-common-10.0.29-1.el7.centos.x86_64
Jan 16 11:11:39 Updated: MariaDB-client-10.0.29-1.el7.centos.x86_64
Jan 16 11:11:40 Updated: MariaDB-shared-10.0.29-1.el7.centos.x86_64
Jan 16 11:11:41 Updated: galera-25.3.19-1.rhel7.el7.centos.x86_64
Jan 16 11:11:48 Updated: clustercontrol-1.4.0-2585.x86_64

In /var/log/cmon.log at cmon start i got the message:

2017-01-16 11:16:07 : (CRITICAL) Alarm raised: License expiration.

Do I need a license for Community version now?

  Hi,

  There is no need for a license for the Community version. Of course, it has its limitations but cluster list should be definitely visible. This looks more like an upgrade bug. To diagnose it further we could use an error report generated as per: http://support.severalnines.com/hc/en-us/articles/212425883

  Additionally, please check Chrome's developer's JS console for any errors that may be visible. It might be easier if you'd create a ticket with us including details I mentioned above and we could proceed with diagnosis.

  Thanks,

  Krzysztof

  I'm having the same issue; even after deleting cluster info from /etc/cmon.cnf and re-importing the cluster (MariaDB 10.0 options seems to be missing? only 10.1?) the cluster is still not visible. Notifications about the cluster appear to be working though.

  I had a wrong rpc-key in my /etc/cmon.d/cmon_"name".cnf. 

  The rpc-key must match with token from database: mysql -p -e "select * from dcps.clusters;"

  Thanks! I had my old (correct) key still in /etc/cmon.conf, after deleting that everything worked.
