Description:

Netdata returns all bandwidth related sensors as positive/negative numbers related to the interface. When you are uploading at 10Mbps, the net.eno1 / sent sensor it will report a speed of -10 Mbps. When you are downloading at 10Mbps, the net.eno / received sensor will report a speed of 10 Mbps. This is only useful when you want to put both values on a graph. For automations, graphs, ... it's counter-intuitive that the value is negative also.
