Currently not possible.
The I/O wait data in Hobbit was traditionally tracked by data provided by the "vmstat" command. Since there is no I/O wait data reported by the Solaris vmstat, there is no currently no place to store these data in the existing RRD (trend) databases - at least as they are used for data from Solaris boxes.
What this shows is that the current setup which has a custom set of data for each type of operating system was a poor design. It was inherited from the old Big Brother / LARRD setup - and it was a major mistake on my part not to change it when I created Hobbit.
However, changing this now will require everyone to do a manual export/import of data from their current vmstat RRD files into a new file format. This is just not possible before the 4.2 release, so I'm afraid you'll have to wait a while before you can track these data by default.
