How to audit the bandwidth that is consuming each computer

HI

We have a LAN in which we have noticed since a few days ago that the bandwidth use has increased dramatically.

Is there any software in order to audit consumption per each computer?

Thanks in advance

The only thinkg you can do is to emable SNMP service to each computer and then monitor the traffic of each computer using for example cacti

What switch are you using? Is SNMP cpable to monitor the traffic on each port?

If yes, give a glance to cacti

The switch is a 8 port linksys, model SD208 and the computers are getting DHCP from a DSL 2WIRE router model: RG2701HG-00

The Linksys is an unmanaged switch, I'm not sure about the DSL router.
You may not be able to do anything without adding another device to your network to monitor things.

Great ampranti !

Considering that is my first time with cacti, which values do you consider would be a good and a bad network performance?, in order to do a correct interpretation.

Depends on the network and application you are using

If you are using video streaming is tottaly different from using http based applications.

If you set cacti you will find easily those who use too much bandwidth

So, do you mean that people that it uses alot of video streaming wouldn´t be indentified by cacti or any SNMP application ?

Thanks.

The opposite.
I mean that will be identified because of their high bandwidth usage

In case that I could have an SNMP device:

1. how cacti and SNMP services should be installed?
2. Which switch/router would be an economic and a good device?

Thanks
