Hi,
 
I gave this a try and the vmstat items show up only as objects and not
graphs.   Part of the host entry is below for this host.

I am sure I am missing something really easy.   Any ideas?

Hi Henrik, 

Thanks, it works .. maybe it will be more comprehensive and impressive if it
will give graphical I/O stat per filesystem ?

Hi,

the Hobbit mailing list - hobbit at hswn.dk - really is the best place for
support questions.

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


Regards,
Henrik
