<p>hi Richard,</p>
<p>thanks for that input, will see what I can do with it.</p>
<p>I do store data and graph it so I can keep track of things :)</p>

<p>hi all, I am just writing some scripts to gather performance data from iostat... or at least trying... I would like to completely skip the first output since boot from iostat output and just get right to the period I specified with the data current from
that period. Is this possible at all?</p>

<div>NB, this is just a derivative of a sample period. A better approach is to store</div>
<div>long-term trends in a database intended for such use. If that is too much work,</div>
<div>then you should consider storing the raw data that iostat uses for this:</div>
<div>
<div style="margin: 0px; color: rgb(76, 47, 45); font-family: Menlo; background-color: rgb(223, 219, 196);">
kstat -p 'sd::/sd[0-9]+$/'</div>
</div>
<div><br>
</div>
<div>or in JSON:</div>
<div>
<div style="margin: 0px; color: rgb(76, 47, 45); font-family: Menlo; background-color: rgb(223, 219, 196);">
kstat -jp 'sd::/sd[0-9]+$/'</div>
