this is ps -ef output.
I want to know what C is meaning.

[RAC_1]

cpu on which it is running. man ps for details.

[???_185]

C is cpu utilization.But How can I understand this value,
is it percentage of 16 cpu processor?
I execute glance.
the pid cpu usage is like this.
User CPU Util Cum Disk Thd
Process Name PID PPID Pri Name ( 1600% max) CPU IO Rate RSS Cnt

63.8 is current value or 3.2 is ?

[RAC_1]

C column indicates the cpu on which process is running. What exactly you are lokking for??

[???_185]

I mean please tell me how can I intepret the value.
it it kylobytes? or just percentage in total cpu?

Hi,

cpu : Processor utilization for scheduling. The default heading for this column is C.

# man ps for more details

hi,

u may like to refer to this:

http://www1.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000007951429

The processor utilization is a variable used by the kernel in computing
the short-term/dynamic priority of a process. In general, the higher
this number, the more CPU intensive a process is (i.e., it utilizes the
CPU more). The significance of negative numbers is really an issue of
representation. For some unknown reason, the variable is declared as a
signed char, but is treated as an unsigned char throughout the kernel.
Thus, a -1 really means a 255, which indicates the corresponding process
is a real CPU hog. This will be fixed in the future. For now just
know that higher/negative numbers indicate the corresponding process is
really CPU intensive.

regards.

C means Processor utilization for scheduling in man. what does it mean scheduling? I think this isn't real cpu utilization? right?

[Joseph Loo]

hi,

have u read my reply? read it cause it should be easy to understand.

regards.

[Muthukumar_5]

Processor scheduling means scheduling (changing) priority of process while running. See man page of nice command.

It is dealing all about.
