Xiostat is the program I wrote to give us a faithful recounting of the Linux kernel's disk IO stats after we discovered the problems with iostat's numbers . I've now finally gotten around to putting it up on the web and making a page 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 , 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 I kept automatically typing 'xiostat' instead of 'iostat'.)
