I thought that kprobes is quite cool and imagined that systemtap was just a interface on the top of that. But it isn't. It provide the environment, including it's own script language. kernel developers just write small script and then stap will make the appropriate kernel modues to probe anywhere inside kernel and will get the result show in some way. It's not the embedded, it's introduced a new concept in the old low level programming world.
