I/O tracing using blktrace The Linux kernel can collect events about all state changes of I/O requests. Later, the blktrace utilities can derive data from these events. About this task You can collect data about I/O requests with the help of blktrace (see Figure 1 ).

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: a kernel component, a utility to record the i/o trace information for the kernel to user space, and utilities to analyse and view the trace information.

Show activity on this post. I am trying to get access to a block level I/O trace of a cloud benchmark. Ive looked at YCSB, Rain and a few other benchmarking suites, but none of them offer block/byte level logging. I am thinking of just running one of these benchmarks and using blktrace/blkparse to get the I/O trace but the problem with that is ...

https://stackoverflow.com/questions/21459259/blktrace-to-measure-the-io-performance
Blktrace. Low-overhead, configurable kernel component which emits events for specific operations performed on each I/O entering the block I/O layer. So, iostat is generic tool to output statistics; and blktrace is tool to capture and output more information about all I/O requests served in the time when tool was active.
