Factory Sensor results incorrect when adding two SNMP traffic sensors for linux devices



Hi I have 4 Dell servers (Poweredge R730XD) with Linux installed on them. And their interfaces are bonded together (bond0). I monitor this bond interfaces using a PRTG SNMP traffic sensor. Now I have created a PRTG Sensor Factory and added all four bond0 interfaces as shown below.

  1. 1:Out channel(12205,1)+channel(12209,1)+channel(12294,1)+channel(12335,1)
  2. 2:IN channel(12205,0)+channel(12209,0)+channel(12294,0)+channel(12335,0)

But when I add the traffic of my 4 servers one by one, the traffic is about 1 gigabit per second. But when I put in the sensor Factory, it shows the traffic around 890 Mbps.

What is the problem? Did I miss a setting?

Hi there,

Please validate that the scanning interval of the Factory Sensor is the same or at the best greater as the scanning interval of your Traffic Sensors? If this is no the case, wrong results can be the result.
