SNMP TrafficGrapher

STG is another handy snmp graphing tool. Unlike other tools, this one is a small windows application that draws graphs like MRTG but not average graphs. STG is small and quick. It doesn't even need to be installed, no DLL hell. STG is suitable for drawing live traffic graphs while testing throughput of links.

Beware of SNMP security risks when you enable SNMP on your hosts. Even with access-lists in place, hosts are still vulnerable to different kind of attacks.
