Python网速监控
Python网速监控脚本
功能: 统计网卡接收和发送的总流量,计算每秒的网速
代码如下:
#!/bin/env python36 import sys import threading import time # 单位换算 def unit_conversion(byte): byte = int(byte) if byte > 1000: res = byte / 1024 if res < 1000: res = float('%.2f' % res) return str(res) + 'k' elif res < 1000 * 1024: res = res / 1024 res = float('%.2f' % res) return str(res) + 'm' else: res = res / (1024 * 1024) res = float('%.2f' % res) return str(res) + 'g' def get_net_data(netdev): with open('/proc/net/dev', 'r') as f: for line in f: if line.find(netdev) >= 0: receive = line.split(':')[1].split()[0] transmit = line.split(':')[1].split()[8] return float(receive), float(transmit) def speed_monitor(netdev): while True: receive_old, transmit_old = get_net_data(netdev) time.sleep(1) receive, transmit = get_net_data(netdev) print('recevice' + unit_conversion(receive - receive_old) + '/s') print('transmit' + unit_conversion(transmit - transmit_old) + '/s') if __name__ == "__main__": if sys.argv[1] == "t": receive, transmit = get_net_data(sys.argv[2]) print(unit_conversion(receive)) print(unit_conversion(transmit)) elif sys.argv[1] == "s": threading.Thread(target=speed_monitor,args=(sys.argv[2],)).start()
