I mean the way in which they are calculated. Linux Get Cpu Usage Of Process how will i make use of the sourcecode used by top command in calling the program to display the processes, to be used in my bankers program in C, to test S 09:05 109:02 /app/fiaccad As you can see above the "top" displays 0.0 in the %CPU column whereas "ps" reports "104" in its %CPU column for the same process / command The task's share of the elapsed CPU time since the last screen update, expressed as a percentage of total CPU time.

Ps Show Cpu Usage Join our community today! Linux Cpu Usage Per Process For example in unix systems at /proc/uptime gives information of uptime of the system and the value is dynamic since it would be different every time you poll.

Continually adding commands to your own knowledge base is just as important.

Troubleshooting High Cpu Utilization In Linux The field code for processor usage is "c".
T_T Reply Link nixCraft May 20, 2009, 7:46 amYour load average looks normal to me. Currently, it is the CPU time used divided by the time the process has been running (cputime/realtime ratio), expressed as a percentage. There are a lot of options/commands to find the same. his comment is here And how to interpret the CPU usage from ps compared to that of top?
It has done so in 15.3% of its lifetime. Linux comes with various utilities to report CPU utilization. Rent clothing in Frankfurt / Being warm without cold weather clothing Is there a reason why similar or the same musical instruments would develop? There must be some way of piping top into other commands.

It allows you to view and control the processes running on your system. this is not a dyadic cosine-product Sort an array of integers into odd, then even At what point is brevity no longer a virtue? If it is set as 2 seconds, does the output mean the average % CPU usage just within that 2 seconds timeframe?Thanks. Can someone please explain the CPU load percentage as it relates to multi-core or multi-cpu machines.
My top is different to your top. –boehj May 29 '11 at 4:00 You're the one with the different top so you would be in a position to say. This becomes a bottleneck in the system.

If the process was started less than 24 hours ago, the output format is " HH:MM", else it is "mmm dd" (where mmm is the three letters of the month). It is like asking someone to calculate the speed of a car from a picture. ps will give you something like an average, it measured from the start of the process.
