Unable to Restore to Previous Snapshots

[ginfra]

Hello,

I have inherited responsibility for a Nagios environment and am trying to resolve a number of configuration issues. My first stumbling block is that I would like to bring the env up to date (currently running Nagios XI 5.4.12) but I have discovered that I am unable to revert to previous snapshots, and I am reluctant to do an upgrade without this functionality.

I've tried numerous snapshots but each time receive an error like so:

"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.
Write host configurations ...

Error: Service has no hosts and/or service_description (config file '/usr/local/nagios/etc/services/dc2-fab-g-1.cfg', starting on line 16)


As suggested in other threads, I've tried moving the file in question aside but the file is just recreated once the config is applied again. The config file in question is:

Any advice much appreciated!

Have you tried using the "Write Config Files" as described in the KB article below?

https://support.nagios.com/kb/article/n ... d-144.html

Click on the Delete, Write, and Verify buttons (in the exact same order) and see if there are config errors. You would need to fix the errors first under the CCM before applying configuration. Nagios cannot start/restart with config errors.

Have you done any major changes to the system, e.g. hardening the server, modification of the sudoers, etc.?

Perfect, that worked. Many thanks!
