查看/proc/cpuinfo文件，获取CPU详细参数。

Code example:
cat /proc/cpuinfo

cache size      : 256 KB
fpu             :yes
fpu_exception   :yes
cpuid level     : 5
wp              :yes
flags           : fpu vme de pse tsc msr pae mce...
bogomips        : 5600.27
clflush size    : 64
cache_alignment : 128
address sizes   : 36 bits physical, 48 bits virtual
power management:

三、查看内存
内存使用情况

Code example:
free -m
             total       used      free     shared    buffers     cached
Mem:          1977       1254        722          0        150        564
-/+ buffers/cache:        539       1438
Swap:         3858          0       3858

内存硬件信息

Code example:
dmidecode -t memory
SMBIOS 2.7 present.
 
Handle 0x0008, DMItype 16, 23 bytes
Physical Memory Array
    Location: System Board Or Motherboard
....
    Maximum Capacity: 32 GB
....
 
Handle 0x000A, DMItype 17, 34 bytes
....
Memory Device
    Array Handle: 0x0008
    Error Information Handle: Not Provided
    Total Width: 64 bits
    Data Width: 64 bits
    Size: 4096 MB
.....

四、查看网卡
网卡型号

Code example:
lspci|grep-i 'eth'
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168BPCI Express Gigabit Ethernet controller (rev 06)

参数和指标

Code example:
ethtooleth0
Settings foreth0:
    Supported ports: [ TP MII ]
    Supported link modes:   10baseT/Half10baseT/Full
baseT/Half100baseT/Full
baseT/Half1000baseT/Full
    Supported pause frame use: No
    Supports auto-negotiation: Yes
    Advertised link modes:  10baseT/Half10baseT/Full
baseT/Half100baseT/Full
baseT/Half1000baseT/Full
    Advertised pause frame use: Symmetric Receive-only
    Advertised auto-negotiation: Yes
    Link partner advertised link modes:  10baseT/Half10baseT/Full
baseT/Half100baseT/Full
    .....
    Speed: 100Mb/s
    Duplex: Full
    .....
    Link detected:yes

五、查看硬盘
挂载和使用情况

Code example:
df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1            323M  148M  159M  49% /
tmpfs                 989M     0  989M   0%/lib/init/rw
udev                  984M  172K  984M   1%/dev
tmpfs                 989M     0  989M   0%/dev/shm
/dev/sda9            444G   62G  360G  15% /home
/dev/sda8            368M   11M  339M   3% /tmp
/dev/sda5            8.3G  1.5G  6.5G  19% /usr
/dev/sda6            2.8G  551M  2.1G  21% /var

分区详细信息

Code example:
fdisk -l
 
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/Osize (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0001ef9d
 
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1  *           1          43      340992   83  Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2             43       60802   488042497    5  Extended
/dev/sda5             43        1137     8787968   83  Linux
/dev/sda6           1137        1502     2928640   83  Linux
/dev/sda7           1502        1994     3951616   82  Linux swap / Solaris
/dev/sda8           1994        2043      389120   83  Linux
