How does HTOP gather information like CPU consumption, memory consumption etc by every process and the whole system? I am not familiar with any operating system specific api (like socket api) that is provided by linux in order to gather those statistics.

Well, I'd point you to the htop sources, first.

Then, operating systems like Linux have a lot of interfaces to get those information. Some of these metrics are available via the classical /proc pseudo-filesystem, or via /sys/; others might be only available via ioctls or specific system calls (e.g. getgid).
