Substantially of modern-day operating system performance takes place in and close to the kernel. That is a issue when you are utilizing monitoring and observability instruments or incorporating small-amount stability applications due to the fact hooking into kernel functions is complex. Even Linux, quickly available and with its technique of run-time-loaded kernel modules and modifiable source code, tends to make it really hard.
At the time you started rolling your very own kernel-stage applications, you’d rapidly conclude up with a virtually unmaintainable stack of modules and a kernel that only labored for your application. Then there is the challenge of
