显示cpu使用率最高的进程
ps -eo pid,pcpu,args | sort +1n
1, 主板信息
  .查看主板的序列号
  --------------------------------------------------
  #使用命令
  dmidecode | grep -i 'serial number'
  #查看板卡信息
  cat /proc/pci
  --------------------------------------------------
  2, cpu信息
  --------------------------------------------------
  #通过/proc文件系统
  1) cat /proc/cpuinfo
  #通过查看开机信息
  2) dmesg | grep -i 'cpu'
  #
  3)dmidecode -t processor
一、CPU大小
[root@idc ~]# cat /proc/cpuinfo |grep "model name" && cat /proc/cpuinfo |grep "physical id"
model name: Intel(R) Xeon(TM) CPU 2.80GHz
model name: Intel(R) Xeon(TM) CPU 2.80GHz
model name: Intel(R) Xeon(TM) CPU 2.80GHz
model name: Intel(R) Xeon(TM) CPU 2.80GHz
physical id    : 0
physical id    : 0
physical id    : 3
physical id    : 3
[root@idc ~]#
说明：Linux下可以在/proc/cpuinfo中看到每个cpu的详细信息。但是对于双核的cpu，在cpuinfo中会看到两个cpu。常常会让人误以为是两个单核的cpu。
其实应该通过Physical Processor ID来区分单核和双核。而Physical Processor ID可以从cpuinfo或者dmesg中到.
flags 如果有 ht 说明支持超线程技术
判断物理CPU的个数可以查看physical id 的值，相同则为同一个物理CPU
可以看到上面，这台机器有两个双核的CPU，ID分别是0和3，大小是2.8G。
二、内存大小
[root@xbidc ~]# cat /proc/meminfo |grep MemTotal
MemTotal:              1034612 kB
[root@xbidc ~]#
三、硬盘大小
[root@xbidc ~]# fdisk -l |grep Disk
Disk /dev/sda: 300.0 GB, 300000000000 bytes
  --------------------------------------------------
  3, 硬盘信息
  --------------------------------------------------
  #查看分区情况
  fdisk -l
  #查看大小情况
  df -h
  #查看使用情况
  du -h
  #
  hdparm -I /dev/sda
  #
  dmesg | grep sda
  --------------------------------------------------
  4, 内存信息
  --------------------------------------------------
grep命令查看进程  1) cat /proc/meminfo
  2) dmesg | grep mem
  3) free -m
  4) vmstat
  5) dmidecode | grep -i mem
  --------------------------------------------------
  5, 网卡信息
  --------------------------------------------------
  1) dmesg | grep -i 'eth'
  2) cat /etc/sysconfig/hwconf | grep -i eth
  3) lspci | grep -i 'eth'
  --------------------------------------------------
  6, 鼠标键盘和USB信息
  查看键盘和鼠标：cat /proc/bus/input/devices
  查看USB设备：cat /proc/bus/usb/devices
  查看各设备的中断请求(IRQ):cat /proc/interrupts
  7, 显卡信息
  --------------------------------------------------
  1)lspci |grep -i 'VGA'
  2)dmesg | gr
ep -i 'VGA'
  --------------------------------------------------
  8, 声卡信息
  --------------------------------------------------
  1)lspci |grep -i 'VGA'
  2)dmesg | grep -i 'VGA'
  --------------------------------------------------
  7, 其他命令
  .用硬件检测程序kuduz探测新硬件：service kudzu start ( or restart)
  .dmesg (查看所有启动时检测到的硬件信息)
  .lspci (显示外设信息, 如usb，网卡等信息)
  .cat /etc/sysconfig/hwconf
  .mpstat
  8, 需要手动安装的工具
  lshw,hwinfo,hal-device-manager
