NTOP might support computing those sorts of statistics by monitoring
traffic to and from that system (even when running *on* that system):

...but not as much as one might think, given that
1) libpcap works on many platforms, including Solaris, so
packet-sniffing programs can be pretty portable;
2) "dumb tty" programs should work on just about any UNIX on the
planet;
3) curses has been around for ages, so "full-screen tty"
programs should work on just about any UNIX on the planet;
4) the major GUI toolkits have been ported to most if not all of
the UNIX+X11's on the planet;
so a lot of software out there works on multiple platforms (and I
suspect a lot of it that doesn't could be made to do so with a little
attention paid to portability).
In particlar, according to the "Overview" page on the NTOP site, NTOP
runs on
"Unix (including Linux, *BSD, Solaris, and MacOSX)
Win32 (Win95 and above)"
