It's great how you can over-ride the port name template under SNMP COMPATIBILITY OPTIONS. However, I would like one additional variable for the naming: "Device Name" and/or "IPv4 Address/DNS Name."
When you are adding sensors to a Library or simply looking at Sensors in the sensor section, having the device name as part of the sensor name would make it very helpful.
The variables could be [device] and/or [IP/DNS].
Port Name Template
Define how the name of SNMP sensors created on a device will be put together. Enter a template using several variables. When adding new sensors, PRTG scans the interface for available counters at certain OIDs. At each OID usually several fields are available with interface descriptions. They are different for every device/OID. PRTG will use the information in these fields to name the sensors. If a field is empty or not available, an empty string is added to the name. As default, ([port]) [ifalias] is set as port name template, which will create a name such as (001) Ethernet1, for example. You can use any field names available at a certain OID of your device, among which are: •[port]: The port number of the monitored interface. •[ifalias]: The 'alias' name for the monitored interface as specified by a network manager, providing a non-volatile handling. •[ifname]: The textual name of the monitored interface as assigned by the local device. •[ifdescr]: A textual string containing information about the monitored device or interface, for example, manufacturer, product name, version. •[ifspeed]: An estimate of the monitored interface's current bandwidth (KBit/s). •[ifsensor]: The type of the sensor, this is SNMP Traffic or SNMP RMON. This is useful to differentiate between your SNMP Traffic and SNMP RMON sensors.
