Hi All,
We are still facing few issues on Nagios GUi.
We can see that service checks are working and alerts are going even everything is appearing in CCM.
But nothing is appearing GUi. Status showing 0 hosts/services
service_status.PNG
We tried restarting nagios, apache
Code: Select all
1032 /etc/init.d/httpd stop
1033 /etc/init.d/nagios stop
1035 /etc/init.d/nagios start
1036 /etc/init.d/httpd start
But nothing helped.
The only thing we could see is in messages log.
Code: Select all
Oct 8 02:28:09 ndo2db: Error: queue send error, retrying...
Oct 8 02:28:10 ndo2db: Message sent to queue
Could you please help here.

Hi,
We have tried starting "ndo2db" also. Still no luck.Als we see that "ndo2db" error is in log file for long time. Hence we are not suspecting this is causing "GUI" not coming up. (Correct me if I a mwrong).
Here is the brief summary:
GUI is working (partially). Home page, CCM, Admin Page is shwoing in correctly. But only when we do "Service Summary" "Service Overview" tab under Homepage, the Dashboard are not showing up. This issue is occuring since last night. However service checks are happenign in background and alerts are received. Only issue is Dashboard is not showing up.
We checking below:
1. No changes were made in http.conf file
2. Also no other files modified in last 2 days
Any sugestions?

Hi
Few things we noted here.
GUI showing everything properly for one normal user. It is not working for any other users including admin users.
If you login to the nagios core url instead of nagiosXI URL as any user, GUI is showing everything properly
http://Hostname/nagios (core) -----> showing everything properly for all the users
http://Hostname/nagiosxi (xi) ------> showing everything properly for only one normal user
The user, who is able to view everything, is having less privileges compared to the other admin users.
Regards
Tino
