Continuing with this debugging. I think I understand the point about needing a
shell permission to write output to the terminal window.
I've now replaced the shell on the remote host with /bin/false and eliminated
the password for the nagios user on the remote machine. If I leave the password

Thanks for the suggestion, gave that a try, or more precisely:
sudo su nagios -c "more /proc/loadavg"
after removing the password for user nagios and setting the shell to /bin/false.

Some more information and experimentation today.
After reading the NRPE manual, I noticed that they refer to being able to log

does the nagios user have a password.
Both the check_load and check_disk plugins are owned by nagios:nagios and have
-rwxr-xr-x permissions, so what is the difference?
Any suggestions appreciated.
