Default Check

check_load
OK - total load average: 2.36, 1.26, 1.01 |'load1'=2.36;;;0 'load5'=1.26;;;0 'load15'=1.01;;;0

Example using NRPE and Naemon

Naemon Config

define command{
    command_name         check_nrpe
    command_line         $USER1$/check_nrpe -H $HOSTADDRESS$ -n -c $ARG1$ -a $ARG2$
}

define service {
    host_name            testhost
    service_description  check_load
    use                  generic-service
    check_command        check_nrpe!check_load!'warn=load > 20' 'crit=load > 30'
}
