Hello, We use Multi-Router Traffic Grapher (MRTG): http://oss.oetiker.ch/mrtg/ to monitor switchports on our wan connections. The same could be done for the switchports that PCs are connected to. It runs by itself, collects snmp statistics off switches, PCs, ... and puts them into nice graphs. It has been very valuable for monitoring our internet bandwidth consumption. What it will do: It will monitor amount of bytes or packets in/out of the switch port or any other snmp statistic it can from any host (cpu utilization, ram utilization, free disk space - from any server, switch, PC) What it will not do: Because it operates at low layers, it cannot tell you much about the data beyond some layer 2 type statistics (ie it can monitor discards, crc errors, but cannot monitor udp statistics or tcp statistics). So, it is good for monitoring the amount of bytes passed through a switch port, but bad for giving any detailed look into what types of data is being passed.
