I have got my nagios installation setup ok, however, it does not seem to be able to actually monitor the services,
I keep on getting the error:
(Return code of 127 is out of bounds - plugin may be missing)
However, I have checked the plugins through SSH and they work fine,
Does anyone have any ideas on what I can look for to try and get this working?
I would be very grateful for any tips or advice,
Nagios is not something you can just install and start the daemon. It takes time to configure. You really need to read the documentation. There are many files to configure. If you want to add additional plugin you would need to install them properly as well.
