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.

blktrace is a block layer IO tracing mechanism which provide detailed information about request queue operations up to user space. blkparse will combine streams of events for various devices on various CPUs, and produce a formatted output the the event information. It take the output of above tool blktrace and convert those information into fency readable form.

blktrace is the specialized tool that will provide you with the most information about what is happening inside the block layer. It is great for debugging hard problems, but the amount of information it produces can also be overwhelming. For an initial analysis, other tools may be better suited. BCC tools

Hi all: on the windows system, Is there a tool like Linux blktrace to view block IO? use the tools we can analysis some application‘s IO module, such as randwrite, sequence write , and so on.
io - understanding blktrace from fio tests - Stack Overflow
https://stackoverflow.com/questions/59807948/understanding-blktrace-from-fio-tests
Then I used fio to test the server's IO performance. To better understanding the fio results, during the test, I also used blktrace to capture the block layer IO trace. seqwriete fio --filename=/dev/vdc --ioengine=libaio --bs=4k --rw=write --size=8G --iodepth=64 --numjobs=8 --direct=1 --runtime=960 --name=seqwrite --group_reporting
