iftop界面说明:

界面上面显示的是类似刻度尺的刻度范围,为显示流量图形的长条作标尺用的。

中间的<= =>这两个左右箭头,表示的是流量的方向。

TX:发送流量
RX:接收流量
TOTAL:总流量
Cumm:运行iftop到目前时间的总流量
peak:流量峰值
rates:分别表示过去 2s 10s 40s 的平均流量

iftop: display bandwidth usage on an interface by host

Synopsis: iftop -h | [-npblNBP] [-i interface] [-f filter code]

   -P                  show ports as well as hosts
   -m limit            sets the upper limit for the bandwidth scale
   -c config file      specifies an alternative configuration file
   -t                  use text interface without ncurses

   Sorting orders:
   -o 2s                Sort by first column (2s traffic average)
   -o 10s               Sort by second column (10s traffic average) [default]
   -o 40s               Sort by third column (40s traffic average)
   -o source            Sort by source address
   -o destination       Sort by destination address
