Here is an example of viewing statistics:
cat ft-v05.2015-05-01.000759+0300 | flow-stat -f 10 -S 3 | less cat ft-v05.2015-05-01.000759+0300 | flow-stat -n -p -w -f 26 -S 2 | less flow-cat ft-v05.2017-12-07.170236+0200 | flow-print | less
You can see the flow-stat tips by typing:
man flow-stat
I will give an example of exporting data to another format (for example, in csv, which can then be opened in windows by any convenient program):
flow-cat ft-v05.2015-05-01.000759+0300 | flow-export -f 2 | less flow-cat ft-v05.2015-05-01.000759+0300 | flow-export -f 2 > csv.csv
You can display the list with the specified source address with the following command:
flowdumper -se '"192.168.0.1" eq $srcip' ft-v05.2015-06-17.175701+0300
Export the list only with the specified source address to a file, for example, with the following command:
flowdumper -se '"192.168.0.1" eq $srcip' ft-v05.2015-06-17.175701+0300 > file.txt
Example of exporting from multiple files:
flowdumper -se '"192.168.0.1" eq $srcip' /backup/flows/acct/first/2016/2016-01/ft-v05.2015-06-17* > /backup/result.txt
