I keep reading that RHEL/CentOS 5 supports blktrace, but I can't seem to find the blktrace/blkparse utilities.
Is it that just the functionality is available in the kernel, but the user is left to have to hunt down the latest versions of the utilities on the net?
If anybody knows where to get the latest versions of these utilities I would greatly appreciate it.

I was bored so I looked around just to see if I could find this anywhere. The only place I found it was http://mirror.steadfast.org/debian/pool/main/b/blktrace/blktrace_0~git-20070...
Not sure if it'll work (haven't compiled/run it), but I think it's an unpatched ver.

Thanks Geoff and everybody who posted their replies.
I downloaded the ubuntu git copy and inside there found a link to a site that provides hourly git snapshots of this and other utilities:
Downloaded and compiled it from there.
Thanks again,

tarball and instructions to build... it looks quite straightforward.

The CentOS 5 kernel has CONFIG_BLK_DEV_IO_TRACE=y which is required to use blktrace. There is no such option for the CentOS 4 kernel.
