I am not sure of the specifics of an implementation, but it would be nice to know how much time was spent by the system waiting for soft io, physical io, and swap io, much like Solairis provides. (See sys/sysinfo.h on Solaris for more on this, as well as some other stats that may be of interrest). I am not certain if this is feasable, or if it would require major reworking of any kernel components.
I am currently porting PerfStat (see http://www.instrumental.com/perfstat.htm), a very thourogh performance monitor, to Linux. In doing so I see that Linux has very few built in statistics compared to most other unices. We could use more. Solaris has more system stats than you can shake a log at, and I don't think we should follow that model at all, however, some more stats in the right places could greatly improve the visibility and monitorability of Linux without hurting the effiencey and structural elegance of Linux that allows it to waste bulkoid unices.
