怎么在 Linux 上查看多核负载？

		
								# top 

								# 之后按下数字 1 . 则显示多个CPU

								top - 18:05:48 up 1 day,  2:05,  1 user,  load average: 0.00, 0.00, 0.00

								Tasks: 174 total,   1 running, 173 sleeping,   0 stopped,   0 zombie

								Cpu0  :  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

								Cpu1  :  0.5%us,  0.5%sy,  0.0%ni, 98.9%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

								Cpu2  :  0.0%us,  0.5%sy,  0.0%ni, 99.5%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

								Cpu3  :  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

								Cpu4  :  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

								Cpu5  :  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

								Cpu6  :  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

								Cpu7  :  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

								Mem:   5984824k total,   611628k used,  5373196k free,    26552k buffers

								Swap:  6291448k total,        0k used,  6291448k free,   400584k cached

查看某些或者某个进程的状态？

		
								1、得到 httpd 进程的PID

								# pidof httpd

								21358

								2、通过top指定查看特定的PID

								# top -p 21358        # top -p PID,PID,PID ...

查看硬盘UUID？

		
								## 方法一

								# blkid

								## 方法二

								# ls -l /dev/disk/by-uuid
