blktrace is a block layer IO tracing mechanism which provides detailed
information about request queue operations to user space. This package includes
both blktrace, a utility which gathers event traces from the kernel; and
blkparse, a utility which formats trace data collected by blktrace.
You should install the blktrace package if you need to gather detailed information about IO patterns.
