You might take a look at the Ganglia source code. It products metrics like that in fairly focused functions so it's more readable then top. The file you're intrested in is here: http://cvs.sourceforge.net/viewcvs.py/ganglia/monitor-core/gmond/machines/freebsd.c?rev=1.7&view=auto If you want to play with the whole thing, the sysutils/ganglia-monitor-core port may be of use. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
