问题描述
是否有一种方法可以通过psutil获取磁盘IO和网络使用率的百分比.
Is there a way to get disk IO and network usage as a percentage by psutil.
我发现了一些有用的功能.但我不知道如何使用
I found some useful function. But I don't know, how to get as a percentage using
psutil.disk_io_counters()
psutil.net_io_counters()
推荐答案
如果遵循以下方法，则可以百分比形式获得结果:
You can get the result as a percentage if you follow this method:
import psutil
n_c = tuple(psutil.disk_io_counters())
n_c = [(100.0*n_c[i+1]) / n_c[i] for i in xrange(0, len(n_c), 2)]
print n_c
对于我的系统，输出为[18.154375810797326, 40.375844302056244, 40.33502202082432].每个索引都是读取数据后写入的百分比.例如，n_c[0]是百分比write_count/read_count，而n_c[1]是百分比write_bytes/read_bytes同样，您可以获取net_io_counters()的百分比数据.希望这会有所帮助！
For my system, the output was [18.154375810797326, 40.375844302056244, 40.33502202082432]. Each index is a percentage of write upon read data. Eg n_c[0] is the percentage write_count/read_count and n_c[1] is the percentage write_bytes/read_bytes Similarly you can get percentage data for net_io_counters(). Hope this helps!
