Hello,

I have a sensor which read a value every second (accumulative value)

I have to display this value depending of time (second)

Do you know if there is a way to create a custom sensor using "factory sensor" where i can do the following?

(Actual value - Previous Value) / time

Thank you

You might do so with a custom sensor, by remembering the current value in a file/registry key/etc. and comparing it in the next run of the sensor to the then-current value.

When deploying sensors you can select the "Delta" value format, PRTG will then automatically handle the value as a Counter, and measure the ((value-previousvalue)/elapsedtime), the value will be displayed as x,xx/sec in the channel.

Here's an example for the HTTP PUSH Data Advanced Sensor:

I also address the actual difference between measuring a value as Absolute or Deltain the following topic:

This operation mode is supported by most Custom Sensors in PRTG.
