blktrace - 1.2.0-5 main

blktrace is a block layer IO tracing mechanism which provides detailed
information about request queue operations up to user space. There are
three major components that are provided:
.
blktrace: A utility which transfers event traces from the kernel
into either long-term on-disk storage, or provides direct formatted
output (via blkparse).
.
blkparse: A utility which formats events stored in files, or when
run in live mode directly outputs data collected by blktrace.
.
iowatcher: A utility to visualize block I/O patterns. It generates graphs
from blktrace runs to help visualize IO patterns and performance. It can
plot multiple blktrace runs together, making it easy to compare the
differences between different benchmark runs.
