  Hi,

  Some questions to start with:

  Can you ssh from the controller to the galera nodes without password?

  Do you have the ssh_identity and ssh_user set in /etc/cmon.cnf?

  If ssh_user != root , can you do 'sudo' without typing a password (it is also possible to configure cmon using password for sudo) ? 

  Can you send the complete /var/log/cmon.log

  If you are worried about send the cmon.log file here, then please open a support ticket (make sure you are logged into the support system).

  Best regards

  Johan

  Hi Johan,

  Thanks for the quick response.

  
  I do not know where my mind was when he said that there was nothing in the log ... sorry, got confused with alarms.
  I have problem connecting via ssh, the machines were configured before installation and now still connecting without password, but can not ccontrol.

  My cmon.cnf:
  ssh_identity = ~ / .ssh / id_rsa
  ssh_user = root

  cmon is attached.

  Best regards

  Ricardo

  Hi Johan,

  Everithing is OK.

  Thanks for your questions, made ​​me think ...
  The setup of ssh_identity=root /.ssh/id_rsa was missing and he did not accept the use of "~ /". : (
  Just one thing, why the installation everything worked and now not?
  This is the second installation I do and am having many problems, which did not happen in the first (2 months and a half ago), a change in the software or in the installation script was done?
  This situation makes me apprehensive about a possible upgrade in production ...
  
  Again thank you for your attention.

  Best regards

  Ricardo

  to

  ssh_identity = /root/ .ssh / id_rsa 

  Save and exit

  service cmon restart

   

  Thanks

  Hi Johan

  As I mentioned, everything is working now.
  
  But tell me, was there any change in release or in the installation script?

  Again thank you for your attention.
