Ubuntu server is running at 100% cpu when booting. Htop is not showing any process above 2-3% usage. Is there any way to investigate which processes using the cpu? Htop usage in terminal

may miss commands if they executed and finish too quickly, such as when I'm compiling C++ applications. You can quit and restarthtop
and look immediately when the output shows up, or you can trysystemd-cgtop
to see which cgroup has processes that using the most CPU – Daniel T Feb 13 '24 at 10:10
