pyifstat

python写的ifstat，用于查看当前带宽(流量)占用情况

借用ifstat的介绍： ifstat is a tool to report network interfaces bandwidth just like vmstat/iostat do for other system counters. It can monitor local interfaces by polling the kernel counters

#!/usr/bin/env python
import time
import sys
if len(sys.argv) > 1:
INTERFACE = sys.argv[1]
else:
INTERFACE = 'eth0'
STATS = []
print 'Interface:',INTERFACE
def rx():
ifstat = open('/proc/net/dev').readlines()
for interface in ifstat:
if INTERFACE in interface:
stat = float(interface.split()[1])
STATS[0:] = [stat]
def tx():
ifstat = open('/proc/net/dev').readlines()
for interface in ifstat:
if INTERFACE in interface:
stat = float(interface.split()[9])
STATS[1:] = [stat]
print 'In Out'
rx()
tx()
while True:
time.sleep(1)
rxstat\_o = list(STATS)
rx()
tx()
RX = float(STATS[0])
RX\_O = rxstat\_o[0]
TX = float(STATS[1])
TX\_O = rxstat\_o[1]
RX\_RATE = round((RX - RX\_O)/1024/1024,3)
TX\_RATE = round((TX - TX\_O)/1024/1024,3)
print RX\_RATE ,'MB ',TX\_RATE ,'MB'
