HTTP XML/REST Value Sensor - Calculate Value




my example is:

Value is in bytes and I need to display it in GigaBytes.

Is that possible or planned?

Kind Regards, Markus

Hello Markus,
thank you for your post.

The HTTP XML/REST Value Sensor only queries data in a "Custom" unit, so it can't do the conversion directly, this leaves two alternatives:

  • Use a Sensor Factory Sensor to convert the value from bytes to something else, this will result in having two distinct sensors.
  • Open-up the channel settings from the Value channel of the current sensor, you may then enter a Scaling Division or Multiplication factor to convert the result from the sensor.

Note: If you're unable to locate the Scaling Division or Multiplication settings in the channel's settings please update to the latest PRTG version first as this is fairly recent.

Please note that other sensors (that require the XML data to be in a specific format) allow you to set the "Unit" to bytes, this way you'll be able to take advantage of the Channel Unit Configuration to convert the result automatically in PRTG:

Best Regards,
