Nagios Support Forum

We have a manual install of 5.5.2 running on RHEL6. It is a few years old and we continually keep it up to date. I've been using the bulk cloning wizard to add new hosts over the years and it has worked flawlessly until this month. Recently I went to follow my usual procedure to add a few new hosts (we have about 150) and it fails every single time now when writing/verifying the config at the end.

The failures change. Sometimes it's the service file, sometimes it's the host file:

I went and looked at the config files and I can see it wrote the new ones, but as it mentioned the configs are bare bones and missing most of the options as compared with the hosts that I am copying. Doesn't matter which host I choose.

Any assistance would be appreciated.

Can you give us an example host definition of the object that you are trying to clone? Do you have any config errors at the moment, other words, can you successfully apply configuration?

Applying a config works successfully always. It only breaks after the clone, which I then have to revert back to the previous version to have it apply successfully. In other words, the clone is putting down incomplete configs that do not pass a sanity check. It does NOT matter which host I clone, the same thing happens to all of them.

For example, if I clone usmdclxp00381 from usmdclxu00281 (FQDN removed for this post)

Here's what the clone script is putting down and why it fails the check:

As you can see it's not filling out ANY of the options.

This is a know issue, but here's how to fix it.

Remove any un-applyable items.
Go to CCM -> Tools -> Config File Management
Delete Files
Write Files

Now the Bulk Import Wizard should work properly to add new items.

The workaround fixed it. Works great now, thank you!
