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.

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