I have MRTG setup via cfgmaker. It gets info back from the CISCO
router my ISP provided with the T1 service. The graphs that are
generated are for the router's interface, the gateway IP for my
network. But, I have traffic from about 8 active IP addresses
provided by my ISP which the router processes.
I've had it setup this way for over a year now and it has been nice.
But, recently, I've found periods where our T1's bandwidth is getting
maxed up. So, I'd like to track down which of our servers is the
source of the high bandwidth usage. The info I get from MRTG is for
the sum of all our traffic, through the gateway. But, we have 4
servers using 8 or so IPs.
Is there a way to change my MRTG configuration such that I can track
the bandwidth usage on a per-IP basis? I'm looking for something like
1 target/graph-set for each of my 8 IPs.

Which Cisco-Router? Do you have the right to change it's setup?

Yes. You may monitor the switch, where all 8 Servers combine their
output to be feeded to the router...

Thanks for the response.

Cisco 2500

Maybe... When I first setup MRTG, my ISP tech guy alternated the
config on the router to allow me access to the SNMP info. He also
provided the community name. So, he may be willing to adjust the
config, if I ask.

My router is not a switch. I have a separate, consumer netgear switch
attached to it.
I'm assuming the Netgear swirch doesn't do snmp... maybe I'm wrong, or
maybe I could upgrade to a new switch that does have snmp? Assuming
it's not too expensive.

Rather small...

That is a problem...

Again you are not telling any Modell-number 
Nor the number of ports you are needing (besides the mentioned num-
ber of hosts that you like to monitor).

That would be the best (if not only  solution. A Cisco 2850 perhaps?

For my _private_ use, that one would be too expensive; but it is
your pocket...
Yours, Holger |
