The Linux top command is one of the stalwarts of Unix-like operating systems. You can press shortcut keys to change how information is displayed on the top dashboard. Top displays critical information about your systems, like CPU and RAM utilization, details about running processes, and more. Model name: Intel(R) Core(TM) i3-4130 CPU 3. Run 'top' in the Linux terminal to launch this utility. Here's the ouptput of lscpu in my machine: Architecture: x86_64 Cpu usage data is contained in the utime and stime fields, as a number of clock ticks (rather than jiffies). 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.
