Hello ,

Thanks for your reply.

Below is the output of the command you have given .

[root@HT-Nagios-Tools1 var]# ls -lad /usr/local /usr/local/nagios /usr/local/nagios/var /usr/local/nagios/var/archives/
drwxr-xr-x. 15 root root 4096 Dec 8 2016 /usr/local

[root@HT-Nagios-Tools1 var]#

The permissions look fine. On my "stock" Nagios Core machine though, the archives folder is group-writable. I am not sure if this is going to make a difference, but you could run: to see if this is going to help.

Did you forget to upload the nagios.cfg file?

Hello,

Thanks for your reply.

Permissions are same earlier as well when it was working fine, Suddenly it stopped working .

Could you please let us know the solution for this .

Can you upload your main conifg file on the forum (nagios.cfg)?

Do you have multiple instances of nagios running on this machine?

What is the output of the command below? Are you using check_mk? What is in the "check_mk.d" directory?

# added by setup.sh of check_mk
cfg_dir=/usr/local/nagios/etc/check_mk.d

Hello,

Thank you for your reply.

Yes we have multiple instance running on the server.

Yes we are using check_mk

You should not have multiple instances of nagios running on the same machine... Normally, the output should look like something like this:

ps -ef | grep nagios.cfg | grep -v grep
nagios 45828 1 0 Dec17 ? 00:03:23 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
nagios 45842 45828 0 Dec17 ? 00:00:03 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg

You will need to run: and check again how many nagios processes are running.

Also, you can temporarily stop using check_mk to see if this is going to fix the issue.
