why a module? a user-space tool/script/deamon is not enough for your needings?

all this information are already exposed into /proc filesystem (that's
a direct interface to kernel data structures) or by several "standard"
linux tools (like free, netstat, loadavg, etc etc). You can write a
script to parse those info and <do what you have to> (we do it this
way).
Anyhow, this discussion is off-topic on debian-devel, and if you
really want to write a kernel module, it's better if you try to locate
a better forum for kernel development, where you will probably also
find information about kernel data structures to inspect.
