This instance of XI has been up for a few years. 318 hosts 1226 services.

Occasionally after adding/changing something we'll get an error on applying configuration.
Usually I look at the error and and figure out what the issue is or worst case roll back to a previous config and start over.

Today I added a host and when I went to apply I get
Error: Service has no hosts and/or service_description (config file '/usr/local/nagios/etc/services/services_WINDOWS_DWS_OITVDC-VDI-04.cfg', starting on line 77)

That file didn't actually exist so I looked in CCM/Services for services_WINDOWS_DWS_OITVDC-VDI-04
There were some services under that config name but they were all marked not active.
We didn't need them anymore so I deleted them then went to reapply.
Same error.

I tried to roll back to an earlier configuration snapshot - same error.
I went to an earlier snapshot - same error.
Restarted the nagios service (this is on RHEL 6.10 ) - same thing.
I removed the host I'd been trying to add and then ran apply - same thing.

I went to Config File Mangement and deleted then rewrote configs.
Verified files and got:
...
Total Warnings: 28
Total Errors: 0

Things look okay - No serious problems were detected during the pre-flight check
...
(The warnings are hosts/services with no contacts and services that are duplicated - we always have these and it's never prevented an apply)
Tried to run apply and got the same error.

I can force checks so it looks like everything is still monitoring - I just can't add or change anything until I get past this.

ok ... this is weird
I ran /usr/local//nagiosxi/scripts/reconfigure_nagios.sh to see if I'd get something more and ... it gave me the same "warnings:28 erros:0 Things look OK" and looked like it went fine.

So I went back into the web interface and there was a new successful snapshot and 'Apply' was no longer red.
I clicked apply anyways - got the same error.
Went back to cli and reran the config - and got a new successful snapshot.

Do you have by chance any files that are "left over" in the "/usr/local/nagios/etc/import/" directory? If you had "bad" confgis in the import directory, the apply configuration process would fail. You would need to delete them, then apply configuration.

There are no files in the ./etc/import directory.

So, when you are using the config file management, you are not getting any errors, and you can apply configuration - can you confirm?

Core Config Manager > Tools > Config File Management > Delete Files > Write Configs > Verify Files > Apply Configuration

Can you PM me your latest profile?

Admin > System Config > System Profile > Download Profile

If I go to Core Config Manager > Tools > Config File Management > and delete then write config files I can then Verify Files and I get:

---
Total Warnings: 28
Total Errors: 0

Things look okay - No serious problems were detected during the pre-flight check
---

If I then click the red Apply Configuration and then the Apply button I get the error.



I just went to Admin > System Config> System Profile > Download Profile and I get this:

Try troubleshooting the profile issue by following the steps, outlined in this article:

https://support.nagios.com/kb/article/n ... d-533.html

Note: It is possible that fixing the sudoers will also fix the apply config issue. Try these steps again (after fixing sudoers):

Core Config Manager > Tools > Config File Management > Delete Files > Write Configs > Verify Files > Apply Configuration

If issue is still not resolved, PM me the profile, and we will go from there.

That did it!
A policy change had shoved a new sudoers at this machine.
After fixing sudoers everything is working now.

TNX!!!
