In Linux, how does one view high CPU usage threads? in Linux, the top tool can display the average cpu usage (user, nice, system, idle, iowait, irq, softirq, etc ), the usage of each cpu is displayed. However, the cpu usage of each thread cannot be displayed. in Linux, how to view high CPU usage the top tool in Linux can display the average cpu usage (user, nice, system, idle, iowait, irq, softirq, etc .), the usage of each cpu is displayed. However, the cpu usage of each thread cannot be displayed. This may occur when the user or system is high in the total cpu usage, but the cpu usage of the process is sorted, there is no user or system corresponding to the process. You can use the following command to find the threads with high cpu usage: $ ps H-eo user, pid, ppid, tid, time, % cpu, cmd-sort = % cpu this command first specifies the parameter 'H' to display thread-related information. the format output contains: user, pid, ppid, tid, time, % cpu, cmd, and then sort it with the % cpu field. In this way, you can find the thread that occupies the processor.
