Nagios Support Forum

One of my collegues was adding a configuration to our nagios test server (Nagiosxi 5.5.8) and left on vacation. I wanted to apply some new checks to the server only to find an error in the configuration. The odd thing is that the error is blank and although the written configs appear to be successfully written I see "An error occurred while attempting to apply your configuration to Nagios Core. Monitoring engine configuration files have been rolled back to their last known good checkpoint." The snapshot command output is empty but it does show 2019-01-15 14:53:44 Config Error 1547585624.tar.gz

What log can show me what may be happening?

Lets run the following and report the output

Here is what I got back.

./reconfigure_nagios.sh

Your config did not verify successfully.

Go to Configure, CCM -> Tools -> Config File Management
Click Delete Files
Write Configs
Verify Files

Work through any errors then repeat the process until the config verifies successfully.

Then Apply Configuration

The problem still exists after running the reconfigure script.

Do you see any errors in the web UI after following the steps, recommended by @scottwilkerson?
Can you show us a screenshot?

When I wrote the configs it gave me a long list of host , service and groups that applied successfully. When I click on verify files I get a blank square.

I poked around a few places on the web interface and when I got to the audit log ... Not sure if this has anything to do with the issue we are experiencing.... but our test server that has the same license as our prod and dr servers is getting the following error.

This feature is part of the Enterprise Edition of Nagios XI. Your trial of this feature has expired. Some functionality may be limited or disabled. Enter your enterprise key or learn more about upgrading to Enterprise Edition.

I looked at the licensing expiration date which shows current and Activation Status is Activated.

Here is the written configs after clicking deleted files

This is what I get when hitting Verify Files

Can you run the following commands from the command line and show the output?
