A customer contacted me asking about this issue on PRTG Network Monitor.

What does it mean? Is there anything to do?

Thanks

Hello,

that means that one Netflow Sensor is getting Netflow Packages from more than one device.

Best Regards.

right, but... it is not a problem, is it?

My customer informed me like it was an alarm.

Thanks

For Netflow v9 Sensors it might actually be a problem and cause incorrect monitoring results. Please use one Netflow v9 Sensor (with an unique port to listen on) per sending device. Should it be necessary to aggregate the stats then, please use the Sensor Factory.
