if you are running a linux based system openNMS is about the best free tool you have.  I would say you already have the tools that you need though depending on what you are trying to accomplish.

MRTG is nice and easy for traffic analysis but not outages... there are a lot of home grown solutions out there.

oh forgot about the best one if you have a managed switch or hub run NTOP it will break down your traffic into netflows

Here is Just for fun monitoring

Scotty_ciscoCommented:
Netflow is good

I liked NTOP though it rocked runs on a linux/unix platform and is very flexable but you have to span a port or have access to a hub so it can see all the traffic.

Agree that NTOP will give you the results you want, acting as a flow collector.

BTW, Here's Cisco's Best Practice guide
http://www.cisco.com/en/US/tech/tk869/tk769/technologies_white_paper09186a00800aea9c.shtml

What version IOS on the 1720? You may need IP PLUS to get the netflow feature.
Have you already enabled netflow on the interface? You have to first enable the flow before you can export it.
 interface Fast 0
  ip route-cache flow

[syntax]
ip flow-export <ip-address> <udp-port> [version 1 | version 5 [origin-as | peer-as]]

ip flow-export a.b.c.d 2055 version 5

>> (C1700-Y-M), Version 12.2(4)YA2

The earliest IOS version still available for 1720 that I can find supporting Netflow is 12.2(15)T17
  c1700-y-mz.12.2-15.T17.bin

In 12.2 you need the "T" train, or "Z" train
  12.2(13)ZH2, 12.2(15)ZL1  both also support netflow

what about ip accounting is there a way to capture that info and graph it?
0
 
Scotty_ciscoCommented:
IP accounting will not give you type of traffic and break it down on a per host basis.

Scotty_ciscoCommented:
If this is in a production enviroment I would stay away from T trains of code as they tend to have other issues that may cause you more heart burn than they are worth.
