What is kernel time and how I can troubleshooting kernel time

[AlbertZOZ]

Hello All,


I am investigating what the kernel is doing on my server, you can see kernel time in CPU chart in below screenshot, it uses 90% of the active CPU usage, then I use Process Hacker to display all processes' user CPU Time and kernel Time, save them in excel and sum up their values, guess what, User CPU time is 69%-75% of the active CPU usage.

Does anyone has any ideas regarding kernel time? how I can debug/troubleshooting who is using kernel time correctly?

Thanks,
