Nagios Support Forum

Dear Support,

We are having issue with the "Bulk Host Cloning and Import" feature, it looks like the host config file generated by Nagios is incomplete. Please see below for the details.

Please advise.

Thanks

Check your configuration file(s) to ensure that they contain valid
directives and data definitions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.

Could you send a screenshot of the screen where you are selecting the services in the wizard?

Thanks for the rely, just pm you the screenshot, basically I selected all items from another host, but it doesn't matter how many items you select, it will just fail.

Thanks

Based on your screenshot you did not select the Name field which is the host_name and onle entered the address field, Name is required and it is the minimum required.

I admit, that this should be documented on the page better, and will request so from out developers

Can you try again selecting the Name field in the first dropdown.

I tried to add the name field from the drop down list, in this case, it's the hostname. The result is the same. We never added name field before and it worked just fine. This feature was broken for the last 3 releases. I wonder whether you are able to re-produce it on your side.
Thanks

After consulting with the developers about the cause of this, we did come up with a cause and that is the file format changes slightly in the newer versions and need to be re-written to be parsed correctyl.

Lets to the following. Remove the erroneous configs for the host/services, in the CCM.

Then

CCM -> Tools -> Config File Management
Delete Files
Write Configs
Verify Files
Restart Nagios Core

This will reset the configs

Now, the Bulks Host Import Wizard should work correctly.

Great! It's working now. Really appreciate it.
