I'm trying to setup a sensor for monitoring my 3 isp interfaces network bandwidth (incoming/outgoing) from my company firewall. I have an older version of PRTG on a system that we are retiring that has this sensor working, but I get a failure "could not create the sensor SNMP Traffice on device xxx. (xxx is the name/ip) The error says that the sensor does not get a response from device. SNMP Credentials are wrong or does not support the required uptime OID. I do see SNMP community string/IP and port number on the old system, but I dont see where to set this on the new PRTG sensor.
problem setting up sensor for FW

The SNMP community settings can be configured on the settings page of the device, under "Credentials for SNMP devices" :)
