How do I calculate the network usage for a particular system?

Hello Experts

Here is the scenario:
We supply a browser based data matching system to a customer - the application is hosted on our site. The customers enters a data matching request which comes through to our server where the data matching takes place and a ‘Yes’ or ‘No’ is sent back to the customer depending on the outcome of the search .

The customer is trying to undertake a network capacity review of thier own network. For this, they want to know the data sizes for each transaction (so the size of the initial request being sent and the result being sent back).

Please could someone advise how I can analyse the size of the traffic being sent returned – are there any tools available on the market and how complicated are they to administer?

Any help much appreciated

    This is the IP traffic monitor.
    It will tell you how much data is sent and received for a particular IP address.

    If you are looking at spending some money, Packeteer Packetshaper devices are great- will analyze size, latency, bottlenecks, etc. they will also prioritze traffic (QoS), but you can buy stripped down versions that only do analysis (called PacketSeeker I think)

    use NTOP.

    Its free, and can monitor and log all the traffic.

    packetshaper can do same, but its primarily used for QOS.
