I have defined on the remote machine's nrpe_local.cfg: command[check_foo]=/usr/nagios/plugins/check_procs -c 1:1 -C foo Running a similar command locally on that machine works fine: $ /usr/lib/nagios/plugins/check_procs -c 1:1 -C foo PROCS OK: 1 process with command name 'foo' But when I try to run the command from the Nagios server, I get the following result: $ /usr/lib/nagios/plugins/check_nrpe -H remote.host -c check_foo NRPE: Unable to read output Whereas other monitored services work fine: $ /usr/lib/nagios/plugins/check_nrpe -H remote.host -c check_procs PROCS OK: 97 processes </blockquote><div> Just to be certain, did you restart the nrpe daemon on remote.host after modifying its nrpe.cfg file? </div></div> -- Mike Saldivar
