> BTW, any other stats that someone would like to see?
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.
