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

Subject Re: Disk I/O check for Linux
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

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?
