B1: Monitoring Network traffic of each PC (or connection) in a network using a switch/router with SNMP support

·      Enable SNMP on the switch or router or device and also set the security feature to allow PRTG to access the device

·      For a windows PC install generic SNMP software from the Windows CD (see corresponding knowledge base article)

·      It is a good idea to note down which PC (or device or leased line, etc.) is connected to which port for later reference

·      Start the "Add Sensor" wizard, choose SNMP, enter the IP and the SNMP login data of the router/switch

·      In the checkbox list check the ports that you want to monitor and finish the wizard

·      Now you will get graphs of traffic for each device that is connected to one of the ports of your device

·      It is a good idea to double click each sensor in the sensor list and edit the sensor name with name of the actual connection

·      If you have several switches/routers/devices you must repeat this procedure for each device until you have created a sensor for each port
