Working but giving separate bandwidth graphs

This plugins worked well but generating separate bandwidth graphs of Linux “eth0” interface. Below is my configuration.

####Nagios Server####
define service{
use generic-service
host_name mail.example.local
service_description eth0 Network
check_command check_nrpe!eth0_network
check_interval 1
}

####NRPE Client####
vim /usr/local/nagios/etc/nrpe.cfg

command[eth0_network]=/usr/local/nagios/libexec/check_network.py eth0
