Is it possible to create a sensor that shows the cumulative value of bytes entering or leaving an ethernet interface? that is, that the current value is the value read plus the sum of all the previous values.

The devices already have a byte counter, but this restarts when the maximum value is reached, and this is not what I'm looking for.

Hi Fernando,

I'm afraid to tell you that it's not possible with PRTG to have an continuously adding counter for ethernet interfaces of a client.

However, depending on your network configuration, you could try implementing Flow sensors in order to count the used bandwidth per IP/server. Flows are a type of monitoring data pushed from network devices to PRTG. You can use it to monitor where data is traveling to and from, and how much. This way it determines which machine, protocol, and user is consuming bandwidth.

Please find more information about this approach here: https://www.paessler.com/manuals/prtg/flow_monitoring
