Karsten , thanks for replying....
It's like this I don't want to take router info, only thing i want is to
graph the usage of my entire IP block per subnet wise.
Normaly we are using CACTI , MRTG , Observium etc... to gather router
information such as CPU , errors , usage etc...
All the systems mentioned above use SNMP to gather info and when it comes
to usage it only poll to a particular interface and plot the usage ......I
hope you had an idea about my requirement :)
