I want to monitor the network traffic on my machines. For this I use the simple
net input like so:
[[inputs.net]] interfaces = ["eth0"]
This works on one machine but not on the other. I’m puzzled by this. I can’t imagine I messed up the config since it is so little and the same config works on the other machine. I also double checked the interface. This is clearly correct.
Could it be some permissions issue? Perhaps the telegraf user is not allow to read from the device? How do I debug this?
I’m using Ubuntu 16.04 and Telegraf 1.2.1.
