Measuring traffic on Windows 2000 Server NICs

Hi

We are running Windows 2000 File and Exchange servers, amongst others. At the moment, they are connected to a 10/100 Mbs switch.

We're looking at buying some new switches, and the idea of 1000Mbs ports for the servers has come to mind. However, before going out and buying a gigabit switch, I'd like to find out if it's actually needed, i.e. are we ever really going to utlise that much bandwidth. The office at the moment is approx 30 users, no bandwidth intensive applications.

Is anyone aware of any (preferably free) monitoring tools that we can use on the server nics to monitor bandwidth use? At the moment, we use one called Networx but I'd like something where the output can be sent to a graph or somesuch.

Thanks in advance.

Hi Dilan77,

First install the snmp service on those computers you want to monitor.

Then use PRTG to monitor the bandwidth <http://www.paessler.com/prtg>
It is free to 3 nodes.

Or use Opmanger from Manage Engine <http://manageengine.adventnet.com/products/opmanager/>
Its capable of doing much more then bandwidth monitoring and its free to 20 nodes.

Hope this helps

Cheers!

Thanks guys.

PRTG seems to be a good piece of software...so far, the NIC on the server usage is averaging about 40Mbs...with the occasional spike up to about 80 Mbs. It has two teamed 100Mbs HP NIC's.

Am I right in thinking that if it continues this way, we should be ok leaving the card as it is, since there is no need for the gigabit interface? As I said, it's a small file server for a small company. The only advantage I can see of 1000Mbs is during the backups, but these take a few hours to complete only anyway.
