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.
