nrpe script

[Andy Shellam]

Have you got sudo configured on your NRPE host?  I get this error on new 
servers when I forget to add the Nagios/NRPE user to /etc/sudoers and 
allow them access to run the plugins without needing a password.

Try running your command as the Nagios/NRPE user on your NRPE host like 
so (alter path to sudo as appropriate):

# /usr/bin/sudo /usr/local/bin/python 
/home/jesterj/report_loadscript_error_log.py

If this works, make sure that the path to your sudo executable is the 
absolute path in nrpe.cfg.
