Centos 7 / NAGIOS / SNMP

I am trying to configure nagios in centos 7 but at the time of configuring it the alerts tells me that they are all of my correct hosts but in Status information it does not give me information, it indicates me the following message

(No output on stdout) stderr:

This I have in the file commands.cfg

define command{
    command_name    snmp_1minute_load
    command_line    $USER1$/check_snmp -o .1.3.6.1.4.1.2021.10.1.3.1 -H $HOSTADDRESS$ $ARG1$
}

define command{
    command_name    snmp_5minute_load
    command_line    $USER1$/check_snmp -o .1.3.6.1.4.1.2021.10.1.3.2 -H $HOSTADDRESS$ $ARG1$
}

define command{
    command_name    snmp_15minute_load
    command_line    $USER1$/check_snmp -o .1.3.6.1.4.1.2021.10.1.3.3 -H $HOSTADDRESS$ $ARG1$
}

And this in a file of my windows hosts called windows.cfg

define service{
    use                     generic-service
    host_name               web1.onemetric.com.au
    service_description     CPU 1 Minute Average
    check_command           snmp_1minute_load!-C public
