Apply Configuration Page Stalls Out, Never Completes

[Srikrishna Murthy Annam]

While adding targets to nagios XI for monitoring, you may see the following messages .....

 * Configuration submitted for processing...
 * Waiting for configuration verification.................. 

 If you've recently updated XI, try restarting the server first. If you're currently running Nagios XI 2011R1.3 there is a known bug that can cause this issue. You'll need to upgrade to the latest version to resolve the issue. If that does not resolve the issue, try editing the configuration for your PHP settings. Open /etc/php.ini file in a text editor and increase the following values.

 

 

  ;;;;;;;;;;;;;;;;;;;
  ; Resource Limits ;
  ;;;;;;;;;;;;;;;;;;;
 
  max_execution_time = 60     ; Maximum execution time of each script, in  seconds
  max_input_time = 60     ; Maximum amount of time each script may spend parsing request data
  memory_limit = 256M      ; Maximum amount of memory a script may consume 

 

 

 After this, run:

 

  service httpd restart

 

 

 Note: If you're running a large installation with several thousand hosts/services, you may need to increase these numbers more to allow enough time and memory for large configuration changes to take effect.

 

 If the issue persists after the above solutions, the issue could be caused by creating a local DNS entry for the Nagios XI server, but failing to add that name entry to the Nagios XI server itself. Example, if you're accessing the XI server from the following url: http://nagiosserver/nagiosxi, you need to verify that the XI server can also resolve that DNS name correctly. The local DNS entry for the XI server needs to be added to the /etc/hosts file.

 

You can observe similar issues if you run out of disk space.
