Error applying configuration

[SavaSC]

Hello,

I am having difficulties applying the configuration on one of my NagiosXI instances (2014R2.7). We retired a device and I am trying to remove it from Nagios. I renamed it then removed it from all Hostgroups, Templates and Parents. I then removed the dependencies and set it to Inactive. After that I deleted it. All of that went fine with no errors. When I went to apply the changes, however, I got this error:

Code: Select all

Error: Invalid max_check_attempts value for host 'Die'
Error: Could not register host (config file '/usr/local/nagios/etc/hosts/Die.cfg', starting on line 16)

All of the Configuration changes show "successfully written!"

I checked and the file "/usr/local/nagios/etc/hosts/Die.cfg" does not exist.

Any ideas about what I might be missing?

Thanks for your help!

After you have a failed apply configuration it reverts to a last good configuration.

If you want to check out that file to see what is wrong with it (and post it here) you can:

Go to Configure > Core Config Manager > Tools > Write Config Files
- Click Delete (it's safe, they get rebuilt)
- Click Write
- Now go look at the file

If you go into the CCM and search for that host under hosts, do you see it?

[SavaSC]

Thank you for your quick response.

I have followed your directions (delete and write the config files) and all the config files show that they were successfully written. That file still doesn't show up under /usr/local/nagios/etc/hosts. I tried to apply the config again with the same error.

That Host does not show up in CCM. I have restarted the server knowing that if it hasn't been properly applied then it will show back up, but it's not there. If it wasn't for the thrown error I couldn't tell that it failed.

Can you check the mysql log for errors? Run the following and post back the results.

Code: Select all

tail -50 /var/log/mysqld.log

[SavaSC]

Sorry about the delay getting back to you. Here is what looks like the relevant information.

Code: Select all

150610 13:57:30  mysqld started
150610 13:57:31 [Warning] option 'max_join_size': unsigned value 18446744073709551615 adjusted to 4294967295

I'm not sure what this "unsigned value" is supposed to be.

I'm not sure what this "unsigned value" is supposed to be.

It is fine.
Your issues with apply config on 2.7 could be related to sudoers. What is the output of:

Code: Select all

visudo -c
grep manage_service /usr/local/nagiosxi/scripts/restart_nagios_with_export.sh

And the output of running a reconfigure:

Code: Select all

cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh

And finally, can you post the file:

Code: Select all

/etc/sudoers

Is there a file called nagiosxi in the /etc/sudoers.d folder?
If so, is needs to be moved out of that folder. Try doing this in a shell on the system.

Code: Select all

cd /etc/sudoers.d
mv nagiosxi /tmp/

After this, try to apply your configuration.

[SavaSC]

I don't have a /etc/sudoer.d folder. I have the following folders under /etc/
sudoers
sudoers.rpmnew

[tgriep]

Try removing the following from the sudoers file

Code: Select all

    # Nagios Core

    # NDO2DB

    # PNP

After removing them, run the following and post back if there are anymore sudoers syntax errors

Code: Select all

cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh
