You need to use check_nrpe from the central Nagios server to your remote
host. Your check_command is running check_procs on the central Nagios
server, not on the remote host. You need on the Nagios server something
like:

define service{
        use                             generic-service
        host_name                       host
        service_description             MEMORY
        check_command                   check_nrpe!check_swap
        }
define command{
        command_name    check_nrpe
        command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -to 30 -c $ARG1$
        }

And, on the remote host, nrpe.cfg something like:
command[check_swap]=/usr/local/nagios/libexec/check_swap -w 100000 -c 50000
