We have recently started the process to upgrade from Centos 7 to Centos 9 using the Windows Hyper-V drive supplied. Installation appears to have worked as we have upgraded and restored the database from old instance to the new.


We have found that the services are doing checks, but the hosts are not and the quick actions is not present, are you able to assist?

The error message is (Return code of 127 is out of bounds. Check if plugin exists)

Hey @tpwebb

Unfortunately moving to different distros or upgrading to newer versions can have its complications. If you still have a backup it may be worth restoring and following the documentation I posted below and see if you still have the same issues. https://support.nagios.com/kb/article/m ... r-892.html
