Answer 1

For tracking open files per process lsof is your friend.

Answer 2

This question is possibly more appropriate on server fault. However check answers to this . It summarizes everything I can suggest. Top should give you the CPU usage both overall as well as split up of all processes currently being executed on your system.

Answer 3

您可以查看perfkit ，但它仍在开发中。
