WEBYou can collect data about I/O requests with the help of blktrace (see Figure 1 ). Hint: While the I/O analysis can be run at the system where I/O is actually being traced, two Linux systems should be used: One that is being traced and the trace data is being redirected through a network connection to the second one for evaluation.

WEBSimilarly, you can do traces over the network. The network 'server' must run: % blktrace -l to listen to incoming blktrace connections, while the client should use % blktrace -d /dev/sda -h <server hostname> to connect and transfer data over the network. Documentation ----- A users guide is distributed with the source.

WEBAug 13, 2020 · Analyzing I/O patterns with blktrace is done in two steps. First use blktrace to log operations, then use blkparse to show a detailed report on the recorded data.. Record I/O-events on the blockdevice /dev/sda for five seconds: . blktrace -w 5 -d /dev/sda. Print contents of the logfile to stdout (use -s switch to show per-program statistics at the end):

WEBMar 28, 2017 · The output of blktrace is also read and stored in a binary format, requiring another tool to analyze it. That tool is blkparse, which crawls through a blktrace generated file and prints it in a human readable way. A trace can be collected for late analysis or the output can be piped directly into blkparse, for a real-time debug session.
