Hi,

We took the backup from Centos7 and restored it to Ubuntu 22.04.

It was successfully done and while accessing the new Ubuntu VM, we observed differences in no of hots/services from our actual prod env.
A lot of them have the status of (Return code of 127 is out of bounds. Check if plugin exists)

Hello @Harshwinder,

A return code of 127 out of bounds is usually a result of the plugins missing from your /usr/local/nagios/libexec folder.
If you look at our backup and restore documentation, any third party plugins or modified plugins will need to have any dependencies installed on your new system. https://assets.nagios.com/downloads/nag ... ios-XI.pdf

I recommend verifying that your plugins are in the /usr/local/nagios/libexec folder and that their dependencies are installed. Any plugins that were added to the system path, but were not located in /usr/local/nagios/ will also need to be copied over manually.
