CPU time is an important resource, and sometimes we need to track the process that consumes the most CPU cycles at some time.In a normal desktop or laptop system, the CPU is in a high-load state and may not cause any problems. But for servers that need to handle a large number of requests, the CPU is an extremely important resource.By monitoring CPU usage over a period of time, we can identify long-term CPU-intensive processes and optimize them, or debug other related issues.In Linux systems, th
