I need to measure the bandwidth of client pc's in a department that will be moved to a new site that is under construction. The 30 workstations are part of a windows 2000/2003 server environment running XP pro. I have been trying to set up MRTG from my client pc to monitor the bandwidth usage so we can decide what type of bandwidth we need at the new site. I havent succeeded yet with using MRTG and would like to know do I have to have SNMP service installed on just my machine or all 30 I am trying to monitor? Do you recommend a different approach?
