Apply Configuration Failure

Posted: Tue Apr 03, 2018 9:45 am

Hi Team,
When ever i am trying to run " apply configuration" button after any change it takes a long time and at the end will show an error message.
Currently i am doing the apply configuration manually.

I tried to verify any errors in the config files.
also i have doubt related to the file permissions as well.
I have restarted and also verified for db error as well.
please find my current file permissions

Any suggestions to start the troubleshooting.
I already did repair_databases

i tried to identify the error by runinng the nagios -v command and getting the similar error for any files (Line 16 (NULL value) )

[root@va10xxx bin]# nagios -v /usr/local/nagios/etc/contactgroups.cfg

Nagios Core 4.2.4

Reading configuration data...
Error in configuration file '/usr/local/nagios/etc/contactgroups.cfg' - Line 16 (NULL value)

[root@vxxxx bin]# nagios -v /usr/local/nagios/etc/servicegroups.cfg

run this

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
Also, can you show the output if this

Code: Select all

cat /etc/sudoers|grep NAGIOS
Finally, can you show us the error you see when running apply configuration in the UI?

This is the problem, someone removed the required nagios entries from the sudoers file

Let your systems administrator know these entries must be in there

Code: Select all

Thank you for the support..

We are starting nagios as root user. do we require the above sudo access? for nagios user?

You should not start nagios as root, it should run as nagios.

Also, yes you need to above because there are certain items that also need to run as the apache user, which is part of the nagios group
