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.

Sorry for hijacking this thread, but this is *mostly* on-topic.

Is there a way to make the above TRENDS setting for all hosts? I tried looking at hobbitgraph.cfg and hobbitserver.cfg, but could not determine any applicable syntax.

PS - I like the added graphs.

Thanks for any assistance you can provide.
