Same Sensor ID

Good day, Today i looked up again in my PRTG server and i faced that i have two different sensors with same name and same ID but with different Traffic. For instance :

  • Sensor (009) TesT : - On Cisco # 1
  • Sensor (009) TesT : - On Cisco # 1

as you can see they are identical but they are on different ports with different traffic. So, i'm wondering how can i identify which sensors belongs to which port if i would have 3000 sensors ? It's bit confused for me, if you faced same problem please share your experience :) .

Thanks. ..

Hello Zimmer,
thank you for your KB-Post.

Could it be that you're confusing the Traffic Sensor's Index ( (009) ) with it's ID ?

The sensor's ID can be spotted within the sensor's overview and also un the browser URL while acessing the object. Please check the following as it explains how to identify/spot the sensor's ID(which is important when setting-up factory sensors).

If you have two Traffic Sensors with the same name, check the settings tab of the sensor, as you will be able to confirm the Interface Number in the sensor's settings. If those ALSO match, then the most likely cause for a different graph is a different scanning interval.

The names for the SNMP Traffic and SNMP RMON sensors follow the Port Name Template, which is by default:

([port]) [ifalias] [ifsensor]

You can change this within the SNMP Compatibility Settings of the parent Device, Group, Probe or Root.

Best Regards,
