Monitoring Bandwidth used by IP address

We are a server hosting facility and want to monitor the bandwidth used by our customers by their individual IP address. We have a 7200 router at our core which would be used for this, but don't use CiscoWorks2000 etc for network management.

Can this be acheived via the IOS? Can someone please give pointers on how to do this?

Thanks.

Re: Monitoring Bandwidth used by IP address

I can’t think of anyway you’ll accomplish this on a per user basis. You can use SNMP to check complete bandwidth utilization but you’ll need an SNMP server to do that. Anyone have some suggestions?

Re: Monitoring Bandwidth used by IP address

Where do the routers keep the logs?

How would I copy those logs from teh router to my PC?

I need to be able to check the weekly performance for one specific router.

Use SNMP on each server, setup a private RO community string and buy Solarwinds Engineers Orion. It will graph the interface traffic over time for you and you can print reports etc.

Re: Monitoring Bandwidth used by IP address

Thanks for your input guys.

I should have made it clearer that I am after a way of being alerted when bandwidth use (by IP address) goes above (selectable) limits. I don't want to restrict bandwidth (yet!) but want to be emailed when an IP address takes more bandwidth than I want.

Solarwinds is a good way of monitoring bandwidth usuage but I have been unable to find a way to get their product to do alerting. Anyone?

Re: Monitoring Bandwidth used by IP address

Cisco (Netflow) and other vendors (HP - IUM) do have products for doing this but as you are probably aware they are fairly expensive. These products address ISP billing requirements which sounds like a lot more than your after.

You may want to look into using a device like a Packeteer Packetshaper. These devices typically manage bandwidth but can be used in a monitor only mode. They have very good reporting and alerting capabilities which may suit your needs.

Re: Monitoring Bandwidth used by IP address

use snmp on the switch that supports the servers on each segment. it is easier to watch the switch port statistics with a tool like mrtg/rrdtool than to pay for a packeteer. it will require a little scripting.

Re: Monitoring Bandwidth used by IP address

Don't all of the above assume that the server in question to be monitored is connecting into the switch via dedicated port (ie not from a 35xx or co-hosting on different IPs but the same hardware)?

If he can meet the above it should work - although then again - that assumes there's no reason for that server to have any local traffic that would also go through that port - or do SNMP stats expose accounting logs down the the layer 3 level within a port?
