<br>
<tt>the Hobbit mailing list - hobbit@hswn.dk - really is the best place for</tt><br>
<tt>support questions.</tt><br>
<br>
<tt>The only I/O measurement built into Hobbit is the data collected from</tt><br>
<tt>"vmstat", which gives you an overall measure of the amount of
time</tt><br>
<tt>spent waiting for disk I/O. This graph is not displayed by default; </tt><br>
<tt>you can make them appear on the "trends" page by adding</tt><br>
<tt> TRENDS:*,vmstat:vmstat1|vmstat5</tt><br>
<tt>to each of the host entries in bb-hosts. That will give you a "CPU</tt><br>
<tt>utilisation" graph that includes the I/O wait time, and a "Block
I/O"</tt><br>
<tt>graph showing the number of blocks read from/written to a disk device.</tt><br>
<br>
<br>
<tt>Regards,</tt><br>
<tt>Henrik</tt><br>
