There are 3 general states your CPU can be in: Idle, which means it has nothing to do. It's a little easier on the eyes than regular old top. Here is a brief look at some of the things that can go wrong and how they affect the CPU utilization.

Löwis 81.2k11138193 If this is true, then why does Space's answer work? –Brain2000 Nov 13 '13 at 17:49 Because Space's answer doesn't work. Instead, you have to read /proc/stat several times: each column in the cpu(n) lines gives the total CPU time, and you have to take subsequent readings of it to get percentages.

Everything is small. For mpstat, there is a INTERVAL param. This number can peak much higher, especially when there is a lot of I/O happening. 0.0 ni - As mentioned above, the priority level a user space process can be tweaked have a peek at these guys Reply Link ben November 16, 2007, 3:30 amis there a GUI version of a CPU usage monitor for KDE?

Linux Total Cpu Usage Reply Ravi Saive says: October 24, 2016 at 11:40 am @Yogita, I think there is no such tools, you need to create a manual script to store the CPU usage information i have got lighttpd running and i need to develop test cases and run tests - provide dynamic content with HTML.
Note however that some swapping, particularly swapping out, is normal. Good old "top" command The top command provides dynamic view of CPU utilization.

Your CPU is not used to 89.2% - it's 100% From this, there is no reason to look at iostat - the system does not need much IO in this state. The total of the user space percentage - us, the niced percentage - ni, and the idle percentage - id, should be close to 100%. It also shows high memory and cpu utilization of a running processess. Appreciate if any one could help me on this.My server is ProLiant DL380 G3 model which is a 32 bit CPU server.
UNIX is a registered trademark of The Open Group. If you think this seems like a lot of activity, think again, because the user-level processing (the us field) is only averaging 2%, while system-level processing (the sy field) is usually Following command will help you to identify CPU utilization, so that you can troubleshoot CPU related performance problems on a Linux based system. Reply Link Lohith March 22, 2011, 9:31 amHi , I am running mpstat -P ALL command and calculating the CPU utilization values.
The system status can be viewed from the command line or using it own web interface. Run free -m command to see memory usage. Htop - Linux Process Monitoring Htop is a much advanced interactive and real time Linux process monitoring tool.
