I have a network with a very low amount of internet bandwidth available.  I would like to install something to track which computers are using up all of the bandwidth and bringing work to a crawl.  I would like to see what is going in/out of the network as well as what is being sent through the network. 

 

Our current setup has all local machines wired to Cisco SR2024C's.  Each of these have a cat cable to a single Cisco SR2024C that has a cat cable to the gateway (The switches are not chained to each other except through the single switch.  I believe someone did this to get around losing internet to all switches if the first one went out.).

 

I have seen a lot about wireshark, but I never could get it to work correctly.  I would like to know if it would be easiest to use a local machine on the network install a device between the network and the gateway, or something else.

 

Any help is greatly appreciated.

Thank you.

This looks like you install on an individual machine to watch traffic on just that machine.

 

No, thank you for the response.

Again this seems to be for one computer.  I would really like something that watches all computers on a network.  I have around 40 computers with under 3Mb internet speeds.  I would really like to monitor who is using up the bandwidth and what they are doing (i.e. streaming radio/videos, watching porn, or actually adding files to our website).

Is this a work environment? Search for network monitoring tools, free or paid. http://www.techrepublic.com/blog/five-apps/five-free-network-monitoring-tools/

It is a work environment.  I'm going to give 1 or 2 of these a try and I'll let you know how it goes.

This is what I use for home network when I had Hughesnet. Yes It is configurable for multiple computers, syncs to a central system, data on individual users. ISP cap limits

Three things to consider:

 

1) most applications that are free are only free for HOME or PERSONAL use, any use in a business environment can result in legal actions. Some companies actively persue this, and Microsoft has been known to find out and report it to the companies not being paid even if it is not themselves (IE: Open office is free from personal use, but not business use.  It is much cheaper, and much less versatile, than MS Office.  Even though microsoft gains nothing they will report a license violation to them so open office can persue legal action and fine your company).

 

2) For a small business most ISP's have basic monitoring available.  You can ask them, if not then look at option 3.

 

3) Try Plixer's flow analyzer, at http://www.plixer.com/Scrutinizer-Netflow-Sflow/scrutinizer-flow-analyzer.html  This works great and they offer a full trial, and a free for business use version that is far from what the full one has, but still very informative. However this can give you the information you are asking for. Be aware that you need to make some heavy duty configuration changes to your network, and you need a system set up dedicated for the monitoring.  This may be more cost heavy than you are willing to go for, but if this company has growth potential this setup would also be scalable to fit.

I can simply advice you to try teh tool that we have in the office Anturis to monitor the PCs and even BYODs. They say that it is easy to isntall and to use and troubleshooting like a bonus.
