python - 测量服务器的 ping 延迟 - Python

Question

我有一个服务器IP地址列表，我需要检查每个服务器是否在线以及延迟是多长时间。

我还没有找到任何直接的方法来实现这一点，而且在准确计算延迟方面似乎存在一些问题。

有什么想法吗？

如果您已经习惯了解析字符串，您可以使用 subprocess 模块将您要查找的数据转换为字符串，如下所示:

>>> import subprocess
>>> p = subprocess.Popen(["ping.exe","www.google.com"], stdout = subprocess.PIPE)
>>> print p.communicate()[0]
