== _xiostat_: better Linux disk IO statistics

[[Xiostat /Programs/Xiostat]] is the program I wrote to give
us a faithful recounting of the [[Linux kernel's disk IO stats
DiskIOStats]] after we discovered the [[problems with iostat's numbers
IostatProblems]]. I've now finally gotten around to putting it up on the
web and making [[a page /Programs/Xiostat]] that explains how to run it
and what its output means and so on.

The current version is a bit slapdash, but I have verified that it
(still) works on bog standard 2.6 Linux kernels (and thus should work on
Debian Sarge, Fedora Core 2+, etc) and Red Hat Enterprise Linux 4. It
should also work on RHEL 3, but I don't have any handy RHEL 3 systems to
test on right now.

Current information on xiostat's status will always be on [[the
xiostat page /Programs/Xiostat]], so check there for status updates
from after this WanderingThoughts entry has been published.

(I am so habituated to using _xiostat_ that when I wrote the [[original
iostat entry IostatProblems]] I kept automatically typing 'xiostat'
instead of 'iostat'.)
