we have some command line ruby/perl scripts that do this, pretty simple.  If you wanted to do this "in" nginx, I guess the easiest way would be using Lua that did a location_capture of stub_status and cached the value ( using http://wiki.nginx.org/HttpLuaModule#ngx.shared.DICT maybe).

Or, have a script that polls nginx stub status every x seconds and writes it out to a static file that nginx can serve.

I'd rather nginx just provide the raw data and I can slice and dice it for my own needs.
