In its default state, perf top tells you. ![]() However, where the top utility generally shows you how much CPU time a given process or thread is using, perf top shows you how much CPU time each specific function uses. pidstat -u 600 >/var/log/pidstats. The first way is to setup pidstat to run in the background and produce data. Note that its entirely possible its many processes in a runaway scenario causing this, not just one. It will also give a readout of users, tasks, CPU load, and memory usage. Sorted by: 44 There are a couple of possible ways you can do this. ![]() top 05:43:20 up 10 days, 20:45, 1 user, load average: 0.29, 0.29, 0. The perf top command is used for real time system profiling and functions similarly to the top utility. How To Check CPU Usage from Linux Command Line top Command to View Linux CPU Load Open a terminal window and enter the following: top The system should respond by displaying a list of all the processes that are currently running. In the following example, the utilization for process YYYY is 150. ![]() ![]() It covers the system load average, CPU utilization, process status etc. Here's the ouptput of lscpu in my machine: Architecture: x86_64 Check CPU usage Utilization on Linux with top command Top is a basic Linux command to display Linux process info. But I want to know the '%CPU' column in top is the percent of CPU usage for a process per 1 core or per all CPU cores? for example, in the following output of top, how many CPU frequency is used by firefox? Tasks: 279 total, 1 running, 277 sleeping, 0 stopped, 1 zombie I want to get the realtime CPU frequency which is using by a process in Linux.
