Parsing nethogs tracemode output
Parsing nethogs
I am trying to parse the output of nethogs -d 1 -t to the following format:
5.65273 767.912
14.2687 1681.15
19.9011 2309.54
where the first (resp. second) column represents the total number of KB/s sent (resp. received) by my machine. Each line is a measurement taken at intervals of 1 seconds (the -d arg).
My attempt until now
By running
sudo nethogs -d 1 -t
I get the following raw output
Adding local address: 192.168.0.23
Adding local address: fe80::cb1b:6973:f77f:34

Now how to I go from this to my desired output? I tried to use awk to sum the outputs for one measurement like this
sudo nethogs -d 1 -t 2>&1 | sed '1,5d;/Refreshing:/d;s_t_ _g' | awk 'BEGIN{sent=0; recv=0;};{if (NF >= 2) sent+=$(NF-1); recv+=$NF;}; END{print sent, recv;};'
but that does not produce any output. I could put the output of sed in a file and then apply awk to each paragraph but I feel like there is a more direct way to do it and one which would give me continuous output which I would prefer.

Just taking the lines that start or don't start with a slash into account:
$ awk '/^[/]/ { sent+=$(NF-1); recv+=$NF }
/^[^/]/ && sent>0 && recv>0 { print sent, recv; sent = recv = 0 }' file
5.65273 767.912
14.2477 1680.58
19.8801 2308.97
This just adds to sent and recv from lines that starts with a slash character. When encountering a line that doesn't start with a slash character, the current accumulated sent and recv values are outputted (and then reset to zero). The output only happens if the variables contain a value greater than zero.
