TL;DR Linux keeps statistics on how much time the CPU spends performing different tasks. Cpu Usage Command In Unix I have a question on how to interpret the CPU usage output from all those commands (top, mpstat, etc)As from my understanding, when a core is doing stuffs, it is fully top The top tool provides a dynamic, real-time view of the processes in a running system. These tools are very useful for system administrators to track each users activity like what they are doing, what commands they issued, how much resources are used by them, how long

Moving down into the process-related section of the display, we find that the process using the most CPU power is top itself; in other words, the one runnable process on this Once booted using SMP, run uname -a to verify that SMP kernel loaded. share|improve this answer edited Jan 13 at 2:23 answered Feb 10 '12 at 14:48 vimdude 1,8801620 7 But you have to install mpstat like you recommend above. have a peek here Düşüncelerinizi paylaşmak için oturum açın.
