If you have a number of Cisco devices you’d like to monitor you might want to check out Fireplotter. Fireplotter is a visualization tool that shows open connections, traffic loads and other pertinent information about your Cisco deployment. The graphs are cute, but not as informative as some other tools that we’ve grown to know and love like MRTG, etc. But, what Fireplotter lacks in intensity it more than makes up for in ease of use and deployment. Also, you can use it in conjunction with other monitoring tools if you just want quick and real-time visual monitoring of bandwidth.
