title: how fio iops logfiles are interpreted?
body: <p>I am using fio for storage benchmarking and fio2gnuplot for plotting graphs, every time I run a test and look into logfiles of iops, second coloumn is always 1 which is iops value and due to this graphs are just a straight line perpendicular to Y axis .Which makes no sense. I tried various iodepths,ioengines but no use.am I using any parameters(options)wrong?</p>
  
  <p>following is my jobfile.</p>
  
  <pre><code>[global]
  
  enter code here
  
  rw=randwrite
  size=128m
  thread=1
  iodepth=2
  ioengine=libaio
  per_job_logs=0
  directory=/home/fio
  
  
  
  [job_512]
  write_bw_log=logfiles_libaio/fio-test_512
  write_iops_log=logfiles_libaio/fio-test_512
  write_lat_log=logfiles_libaio/fio-test_512
  bs=512b
  </code></pre>
  
  <p>and this is the logfile</p>
  
  <pre><code>1, 1, 0, 512
  2, 1, 1, 512
  18, 1, 1, 512
  19, 1, 0, 512
  31, 1, 1, 512
  53, 1, 1, 512
  55, 1, 1, 512
  56, 1, 0, 512
  59, 1, 1, 512
  63, 1, 1, 512
  </code></pre>
