Run ssh-keygen with whatever options you want. Keep the secret key on 
the nagios server and put the public one in the file 
$HOME/.ssh/authorized_keys on the server you want to check. If things 
fail, check the logs for error messages. It's most likely down to 
permissions. They need to be 0600 on the authorized_keys file and 0700 
on $HOME/.ssh.

If you want more indepth explanations, turn to man-pages, the docs 
shipped with openssh, google or, in extreme cases, a paid consultant 
(although I've never yet heard of anyone daft enough not to grasp the 
concept after reading enough docs).
