Configuration is not applying

[Cpt.Ackbar]

Hi,

I am facing issue with Nagios XI. When I make changes via CCM these changes are not visible in overview and is not taken into considiration during monitoring.

It started after kernel update and nagios upgrade.

I have server in EU which has been upgraded this way:
- upgrade to Nagios XI 5.5.8
- kernel upgrade of CentOS 6.10 -> 2.6.32-754.9.1.el6.x86_64

By these steps Nagios stopped to apply changes.

I have also boxes in China and US which were upgraded differently:
- kernel upgrade of CentOS 6.10 -> 2.6.32-754.9.1.el6.x86_64
- upgrade to Nagios XI 5.5.8

By these steps Nagios work without any issues.

I have also script for restarting nagios services becasuse of use mod gearman. Script has these lines:

Code: Select all

#Service Stop Order:
service nagios stop
service mod_gearman_worker stop
service gearmand stop
#Service Start Order:
service gearmand start
#service mod_gearman_worker start
service nagios start
service nagios status

If I aaply it on broken server in EU I am getting this output:

Code: Select all

[root@frkgnagxip1 user]# ./fixworkers.sh
Stopping nagios: kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
done.
Stopping mod_gearman_worker.... Not running.
Stopping gearmand:                                         [  OK  ]
Starting gearmand:                                         [  OK  ]
Starting nagios: done.
nagios is not running

If I apply it on OK server output is:

Code: Select all

[root@KUNGNAGIOSXIP1 user]# ./fixworkers.sh
Stopping nagios: .done.
Stopping gearmand:                                         [  OK  ]
Starting gearmand:                                         [  OK  ]
Starting nagios: done.
nagios (pid 53302) is running...

So I guess something went wrong with nagios service during kernel upgrade. If I switch to old kernel issue still persists.

After applying this command, issue still persists:

Code: Select all

[root@frkgnagxip1 user]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

I tried these steps https://support.nagios.com/kb/article/n ... ce-39.html:

I googled error and get this link (https://support.nagios.com/forum/viewto ... 16&t=49375) but I am not able to see post as our contract has expired and we are waiting for our incredibly slow financial department to pay bill for another year.

Could you please help? It is quite crucial.

Thanks a lot and in case you need more details let me know.

Hello Cpt.Ackbar,

Click on the Admin top menu item and check the status of the Database Backend. If it's not running, Clicking on the Actions wheel will start it. Let us know if this resolves your issue,

Thank you for visiting the Nagios Support Forum!

[Cpt.Ackbar]

Database backend was running. Just to be sure I restarted database backend service via Actions -> Restart. But issue still persists.

@Cpt.Ackbar, Looks like the nagios process wasn't running on the broken server in the EU. Can you run the following commands on the broken server and show me the output?

cat /etc/rc.d/init.d/nagios | grep NagiosRunFile=
cat /usr/local/nagiosxi/scripts/nom_restore_nagioscore_checkpoint.sh | grep lockfile=
cat /usr/local/nagiosxi/scripts/nom_restore_nagioscore_checkpoint_specific.sh | grep lockfile=
cat /usr/local/nagios/etc/nagios.cfg | grep lock

[Cpt.Ackbar]

Code: Select all

[root@frkgnagxip1 user]# cat /etc/rc.d/init.d/nagios | grep NagiosRunFile=
NagiosRunFile=/var/run/nagios.lock
[root@frkgnagxip1 user]# cat /usr/local/nagiosxi/scripts/nom_restore_nagioscore_checkpoint.sh | grep lockfile=
lockfile="/var/run/nagios.lock"
[root@frkgnagxip1 user]# cat /usr/local/nagiosxi/scripts/nom_restore_nagioscore_checkpoint_specific.sh | grep lockfile=
lockfile="/var/run/nagios.lock"
[root@frkgnagxip1 user]# cat /usr/local/nagios/etc/nagios.cfg | grep lock
lock_file=/usr/local/nagios/var/nagios.lock

We need to edit this line in /usr/local/nagios/etc/nagios.cfg

from this

Code: Select all

lock_file=/usr/local/nagios/var/nagios.lock

to this

Code: Select all

lock_file=/var/run/nagios.lock

then run the following

Code: Select all

service nagios stop
killall -9 nagios
rm -f /var/run/nagios.lock /usr/local/nagios/var/nagios.lock
service nagios start

[Cpt.Ackbar]

I have done it. It seems it is working now. Let me double check it tomorrow during my working hours and then we can close this issue. Thanks for your help
