Performance Issue on Nagios XI server

[tthomas]

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.

Try restarting ndo2db process as well.

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

Can you run the following and post the output here to see if there are any errors in the mysqld.log file?

Code: Select all

tail -f /var/log/mysqld.log

I do not see any particular error in mysqld.log. We did shutdown mysql service few times as part of troubleshooting. Only logs for stop/start is there in mysqld.log

Code: Select all
