Thanks Armin , I will try the SW you have mentioned seems like it's not easy to install though :) :) Karsten, I just bought out an example... my company has 2X18's and out of it we are using considerable amount of /24s to access internet . Some subnets are given without proper documentation , so it's very hard to do what you have proposed. What I can do is to install some kind of SW and gather info from my gateway routers :( .....it's helpful if some one can guide me through this :) ...

Hi,

I'm not sure how it is exactly build, but if every /29 uses it's own port a tool like cacti/graphite where you're aggregating all required ports within one graph is easier.

Hi All, I have a requirement to plot a usage graph per subnet. As an example.

I have a 192.168.1.0/24 subnet divided among 32 customers where each one will get a /29 [ 192.168.1.0/29 => Customer A ; 192.168.1.8/29 => Customer B etc... ] ...

Is there any tool to graph the usage of entire /24 subnet ???

Hi, in this case I fully agree with Armin's advice, only wanted to provide a possible way to archive an easy result without activation of netflow/sflow which is possible if all subnets had dedicated ports somewhere in the net. I don't know what information you want to get from your routers, as there are many ways to get a result depending on the information you want and the used vendors. Regards Karsten Am Dienstag, 17.

Chris , Thanks for the info... Let me explain my requirement .... My company has 3 upstream providers and we are serving more than 400 customers ..In that case we have to manage our upstream capacity... When considering capacity managing normally we just transfer a /24 from congested Up stream provider to non congested provider. Issue we have is we don't know exactly the usage of a /24 subnet before transfer. I hope you get an idea about my requirement :) :) :) On Wed, Feb 18, 2015 at 8:40 AM, Methsri Wickramarathna < mmethw2003@gmail.com> wrote:

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 :)
