psutil.net_io_counters()访问发送的字节

Question

嗨，我正在使用psutil，我想要访问bytes_sent。

net = psutil.net_io_counters(pernic=True)

输出=>

{'lo': iostat(bytes_sent=122424, bytes_recv=122424, packets_sent=1408, packets_recv=1408, errin=0, errout=0, dropin=0, dropout=0), 'kvnet': iostat(bytes_sent=3594694, bytes_recv=25226835, packets_sent=28971, packets_recv=29051, errin=0, errout=0, dropin=0, dropout=0), 'eth0': iostat(bytes_sent=5591347, bytes_recv=29589927, packets_sent=33000, packets_recv=46178, errin=0, errout=0, dropin=0, dropout=0)}

当我这么做时：

 sent = psutil.net_io_counters().bytes_sent()
 receved = psutil.net_io_counters().bytes_recv()

我犯了个错误

TypeError: 'int' object is not callable

有什么问题吗？

Answer 1

psutil.net_io_counters(pernic=True)返回一个包含所有接口统计信息的数据集。

为了获得单独的结果，您需要执行以下操作：

net = psutil.net_io_counters(pernic=True)
# Notice no brackets in the end
sent = net['lo'].bytes_sent
received = net['lo'].bytes_recv

# or with the eth0 interface
sent = net['eth0'].bytes_sent
received = net['eth0'].bytes_recv

Answer 2

去掉引号：-

psutil.net_io_counters().bytes_sent
