A better iostat for Linux
== What it is:
This is a Linux program that reports accurate and trustworthy disk IO stats on a Linux 2.6/3.x machine without either making stats up or lying to you when counter rollover happens. The numbers are taken directly from the kernel statistics.
Information on iostat's problems: http://utcc.utoronto.ca/~cks/space/blog/linux/IostatProblems http://utcc.utoronto.ca/~cks/space/blog/linux/LinuxIowait
Information on what IO stats you get from the kernel and what they mean: http://utcc.utoronto.ca/~cks/space/blog/linux/DiskIOStats
(this information is slightly out of date; in modern 2.6 kernels you can get full stats on a per-partition basis, and mxiostat supports this.)
See mxiostat.1 for a manpage.
=== Bugs:
- manpage could stand improvement.
- contains vestigial code that should be removed or in some cases reformed.
- usage is confusing and complex.
