Network speed off by three orders of magnitude about linux-dash HOT 4 CLOSED

Ahh, I see. It's measuring potential speed, not actual speed. I guess I'd rather it output how many KB/s are actually going over the wire at that time instead of a contrived sample.

Instead of chewing up a GB of bandwidth, just check /sys/class/net/[device]/statistics/rx_bytes (and .../tx_bytes for transmit) two times, one second apart; the difference is the throughput of that interface.

That would certainly be a better approach to getting the network speed.

Running a speed test by fetching a file from a distant server isn't that bad either, but as @koehn points out, it chews up 1GB of bandwidth every time the network speed counter is refreshed. Why not just grab simple data from the VPS?

@koehn , you make a good point. I have updated the calculation to report the download speed from cURL for now. I have also changed the file from 1GB to 10MB.

I am also going to try to add in the "rx_bytes" method, which I was not aware of before. It is now on a list of enhancements to help make the data gathering process more efficient and cache-able.

Thanks!
