如何通过psutil获取磁盘IO和网络使用百分比

Question

Is there a way to get disk IO and network usage as a percentage by psutil.

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()

Answer 1

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

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!
