Monitor Server Network traffic

Does anyone know of a free or low cost tool that I could use to monitor network traffic on a server. I'm looking for an application that will show what clients or servers have a connection to a particular server in realtime and how much information is being transferred between the two machines. In essence I am looking for something that does a similar job to ipaccounting on cisco routers, but that can be run on Windows servers.

Thanks in advance for your help

Hello,

Wireshark (http://www.wireshark.org/) is a traffic analyser, looks at the protocol, type of data, source, destination etc. It can be run on Windows. It does not tell you the bandwidth consumption though.

I have searched google and found the following items.  I have never used any of these, so I am not certain if this will help.

Good luck.

Thanks for the suggestions but I've used Wireshark and Netmon before and they don't give me the information that I'm looking for unfortunately. I would like to be able to see the amount of data that is being transferred from one server to another.

Hello,

Assuming your servers are attached to a router, to see the amount of information coming down to the servers you can check the stats on the interface. The command "show interface <interface type / number>" gives you a lot of information. You can get the rate of data coming down to the servers and the amount of data the server is sending.

You can also use QoS if you want more granularity because with QoS you can monitor several protocols using ACLs that are attached to class maps that are in turn used on QoS policies.

Another option is the Cisco SPAN technology - see also http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml

Thanks.

Unfortunately the server in question is not attached to a router and is segregated on its own subnet. I've found a third part app that has resolved the problems that I've been having but thanks for the suggestions
