【问题描述】：

由于我无法在iostat -dx 1 上使用watch 来获取当前的磁盘负载，我想知道是否有其他方法可以做到这一点，例如，使用@987654323 中包含的值进行计算@ 和/或其他一些文件。

根据 kernel.org，映射为：

    The /proc/diskstats file displays the I/O statistics
    of block devices. Each line contains the following 14
    fields:
     1 - major number
     2 - minor mumber
     3 - device name
     4 - reads completed successfully
     5 - reads merged
     6 - sectors read
     7 - time spent reading (ms)
     8 - writes completed
     9 - writes merged
    10 - sectors written
    11 - time spent writing (ms)
    12 - I/Os currently in progress
    13 - time spent doing I/Os (ms)
    14 - weighted time spent doing I/Os (ms)
    For more details refer to Documentation/iostats.txt
