How to see network KB/s up and down on a process in OSX Activity Monitor

In the MS Windows Resource Monitor (cmd > resmon > network > network activity) it is easy to see what process is current sending or receiving data and to what destination.

I'd very much like to see the same in the OSX Activity Monitor but the current columns have me confused. Not really sure how to apply Sent Packets and Rcvd Packets. Because don't packet sizes vary?; this won't show me anything of value.

Activity Monitor doesn't have this ability, you should look into "nettop" from the Terminal app, iTerm, etc. If you run it as 'nettop -d' then it will show the delta between updates instead of the cumulative totals from each process. You can navigate up/down through the process list using the arrow keys.

It's understandably not quite the same but it should do the trick, thanks.

What has me confused by the Activity Monitor view is that there doesn't seem to be a clear indication what the duration is for the cumulative totals. If it says 50MB rcvd bytes, is that in the last 10 seconds / 3 hours / 2 days? How long is this piece of string?

The totals are since process inception. That could be during boot or 5 minutes ago, the data is only for the process actually running. If a process quits and is restarted then the counters reset.
