帮忙介绍下/proc/pid/stat

[oluckly]

例如：
eureka:/proc/3105 # cat stat
3105 (xinetd) S 1 3105 3105 0 -1 8397120 2891 174904 39 44 1 3 111 82 15 0 1 0 3180 10997760 83 18446744073709551615 93824992231424 93824992385284 140735404291344 18446744073709551615 47683386152211 0 0 3674112 2143547135 0 0 0 17 0 0 0 1100


请帮忙介绍下各个数据（尽量吧）代表的意思。

想通过这些数据计算cpu使用率，是不是只要关注user mode jiffies 和kernel mode jiffies

如何计算？

$ man proc
。。。。。。
/proc/[pid]/stat
Status information about the process. This is used by ps(1). It is
defined in /usr/src/linux/fs/proc/array.c.

The fields, in order, with their proper scanf(3) format specifiers, are:

pid %d The process ID.

comm %s The filename of the executable, in parentheses. This is vis-
ible whether or not the executable is swapped out.

state %c One character from the string "RSDZTW" where R is running, S
is sleeping in an interruptible wait, D is waiting in unin-
terruptible disk sleep, Z is zombie, T is traced or stopped
(on a signal), and W is paging.

ppid %d The PID of the parent.

最近看到一个valgrind工具，不知道是否专业。

谢谢楼上的朋友！
请问如何利用时间差获取这个文件数据，来计算此进程的cpu占用率呢？请帮忙给个思路！
