check_network.py

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

Most plugins are used in enterprise environments where nagios user does not have root or sudo privileges. ifconfig cannot be run in such environments which makes the plugin unusable.

You can do almost the same code, but get the byte and packet readings from /sys/class/net/eth0/statistics. Using this method you will not need the subprocess library. Make it more simple and usable.
