Grep values from nethog and netperf

Vote count:

I need to monitor the network activities of a process and the bandwidth of the connection. So I decided to use nethog and netperf combine with grep and awk to write the values to a file.

nethog command: nethogs -t eth0 | grep firefox | awk '{ print $3 }' (I want to take the upload/download speed). The 1st problem is that command doesn't print anything.

netperf command: netperf -H 192.168.1.10 and the output is:

Recv   Send    Send                          
Socket Socket  Message  Elapsed              
Size   Size    Size     Time     Throughput  
bytes  bytes   bytes    secs.    10^6bits/sec  

524288 524288 262144    10.00    **718.62**

I want to print the value on the bottom right but have no idea how to. That's the 2nd problem

Can you guys help me out? Any ideas will be appreciated!
