Re: Return code of 127 is out of bounds - plugin may be missing

Hello!

Try to use this command_line:

    command_line    $USER1$/check_by_ssh -H $HOSTNAME -l nagios -i
/home/nagios/.ssh/id_rsa -E -o StrictHostKeyChecking=no -C
/home/nagios/checkRAID.sh****
where $USER1$ variable is set in resource.cfg file
