libkstat and libdtrace.
The majority of system statistics etc are/can be gleamed from libkstat
eg mpstat, iostat and vmstat make use of libkstat.
Theres intrstat which uses the dtrace library.
For network theres Tim Cook's nicstat from his blog blogs.sun.com/timc
which also uses libkstat...
The source for all these can be viewed at src.opensolaris.org for examples
on how to use them. Though the nicstat source is just from Tim's blog.
Theres a few blogs on howto use libkstat..
I find it easier to use libkstat then on linux where having to open
various /proc/* files and parse each files own format..
(unless theres a libproc on linux to do all this I don't know)
Even then dtrace can help, look at how to add your own dtrace probes to
your application ?

Sean.
