After the upgrade path to version 1.4 I can not see the status of the cluster and have the information:

Cluster details cannot be retrieved. Please check the CMON process status (service cmon status).

I checked but cmon work correctly on port 9500

  Hi Andrzej,

  Do you see the rpc_key value inside /etc/cmon.cnf? This value should be the identical in the following places:

  1) Inside dcps.apis table, the entry for cmonapi's token

  2) Inside /var/www/html/clustercontrol/bootstrap.php under RPC_TOKEN value.

  3) Inside /var/www/html/cmonapi/config/bootstrap.php under CMON_TOKEN value.

  If you have problem figuring those out, you can create a support ticket and we can assist you to fix the problem.

   

  Regards,

  Ashraf

  I find the solution on

  http://support.severalnines.com/hc/en-us/articles/212425903-CMON-1-4-0-released-upgrade-instructions

   

  # Create the new configuration directory
  $ mkdir /etc/cmon.d
  
  # Create the new /etc/cmon.d/cmon_<cluster_id>.cnf file
  # Use the cluster_id in /etc/cmon.cnf to name the new configuration file, e.g., /etc/cmon.d/cmon_1.cnf
  $ cp /etc/cmon.cnf /etc/cmon.d/cmon_<cluster_id>.cnf
  
  # Create the new default /etc/cmon.cnf file
  # Edit /etc/cmon.cnf file and remove all parameters except the following 4:
  mysql_port=<controller mysql server's mysql port>
  mysql_password=<cmon user password>
  mysql_hostname=<controller hostname/ip>
  hostname=<controller hostname/ip>
