you might want to have a look at the Sensor Factory sensor for this purpose.

Its like i was able to handle the bandwidth_in and Bandwidth_out. I will also like to help anyone that has challenge with their aggregation. With my steps, i believe they will be able to achieve their goals with PRTG version 13.


I created a new sensor by clicking on "Add Sensor", it depends on the devices you have created, click on the existing device you have in your configuration. It will list them out, and click on "Continue". You will see Different types of Sensors but click on "Custom Sensor", down below it there is a "Sensor Factory". Click on it. Rename your Sensor Name like Total graph ...... Under Channel Definition: the formula is :

  1. 1: Total Traffic_IN&OUT Channel(ID,0)+Channel(ID,1) where ID is the Channel_ID means the channel numbers in the factory itself and (0) is the Traffic_IN and (1) is the Traffic_OUT.

For Example,

  1. 1: TOTAL GRAPH Channel (2734,0)+Channel(4190,0)+........+Channel(1234,0)+....+Channel(2345,1)+Channel(7890,1)+.....

Thats it!

Sum the channels up will give you the actual bandwidth you want to monitor.

I hope it is well explanatory.
