Why System Monitor doesn't show all processes, though I selected "All"?

I selected "All processes". I see that it eats 2%-4% CPU:

However, in "Resources" all cores are loaded way higher:

"All processes" are selected:

And I run it as sudo

Any ideas? How to see all this hidden CPU activity? Thank you!

The UI is confusing because in the first picture the CPU usage is for all cores; while the second picture shows the CPU usage for each core.

Thus if you've got 8 CPUs and it shows you're using 1%; it's actually worth up to 8% of a single core. Since you have two processes consuming 1% each, that means a single core may be consuming 16% and alternating between CPUs (which is quite common)

The other processes may be consuming more than 0%, but gets rounded to 0% (eg. 0.49% -> 0% even though 0.49% actually means up to 3.92% of a single core). The same happens with the two processes consuming 1%: They may be consuming up to 1.49% which would account for 11.92% each. That's up to 23.84% of a single CPU!

All of this is consistent with what you're showing.

Admittedly process explorer should update its UI to account for the high core of today's computers. I get this problem very often when a process is "consuming 4%" but that's actually 100% of a single CPU when you've got 24 threads...

Also the kernel consumes a bit of CPU and will appear in the graphs but not in the process tab.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
