How to measure router/firewall performance in nice Graphs

Hi Guys,


I have an ASA5510 and an 1841. Each of those devices sit at different clients, so they have no relationship.


What I thin is happening is that the ASA, as well as the 1841, the customers might be exceeding they router capacity. So I'd like to get a tool that can tell you that your device is indeed using 80 or 90% of CPU time. If this tool can present the results in graphics, then it will even be better.


Is there a free tool that can read router's or firewall's performance in a given period of time (for example in a 24 hour period or in a week's period)



thanks in advanced

There are several, all that information is provided by SNMP. PRTG and Nagios are 2 tools that come to mind. Hit google on both products and you will find their download locations.

I haven't dealt with any others but I'm sure there are more. The ones I provided are free.


NetFlow comes with IOS (free) and it's supported under the Cisco 1841.


It does not provide nice graphs, though - just raw data.


It's up to the NetFlow collector to display the nice graphs.
