linux查看主板型号,cpu,内存,内存条数量,网卡等

实现：

查看主板型号

# dmidecode |grep -A 8 "System Information"
System Information
Manufacturer: Dell
Product Name: CS24-TY
Version: A00
Serial Number: 24Z1NL1
UUID: 2656CFCF-887A-0010-BBD8-00269E9C46DC
Wake-up Type: Power Switch
SKU Number: To Be Filled By O.E.M.
Family: Server

上网查DELL CS24-TY，找到说主板型号是DELL PowerEdge C1100

查看cpu型号，主频

# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
8  Intel(R) Xeon(R) CPU           L5520  @ 2.27GHz

 

查看内存

# free -m
total       used       free     shared    buffers     cached
Mem:         32103      31803        300          0        217        953
-/+ buffers/cache:      30632       1471
Swap:        16383        476      15907

 

2.top命令实时显示

查看内存条数

[root@localhost ~]# dmidecode -t memory|grep Size

查看硬盘大小，分区

[root@localhost ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3             119G   17G   96G  15% /
tmpfs                  16G     0   16G   0% /dev/shm
/dev/sda1              97M   32M   61M  35% /boot

 

查看raid卡，raid卡为DELL PERC 6/i

[root@localhost ~]# dmesg |grep -i raid
dracut: rd_NO_DM: removing DM RAID activation
dracut: rd_NO_MD: removing MD RAID activation
ahci 0000:00:1f.2: AHCI 0001.0200 32 slots 6 ports 3 Gbps 0x3f impl RAID mode
megaraid_sas 0000:04:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
megaraid_sas 0000:04:00.0: setting latency timer to 64
megaraid_sas: fw state:c0000000
scsi6 : LSI SAS based MegaRAID driver
[root@localhost ~]# cat /proc/scsi/scsi
Attached devices:
Host: scsi6 Channel: 02 Id: 00 Lun: 00
Vendor: DELL     Model: PERC 6/i         Rev: 1.11
Type:   Direct-Access                    ANSI  SCSI revision: 05

kernel会将开机信息存储在ring buffer中。您若是开机时来不及查看信息,可利用dmesg来查看

 

查看网卡

[root@localhost ~]# lspci | grep -i 'eth'
05:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)
05:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)

lspci 是一个用来显示系统中所有PCI总线设备或连接到该总线上的所有设备的工具

 

查看21号网络流量

# sar -n DEV  -f /var/log/sa/sa21 |grep eth|less

 sar是一个优秀的一般性能监视工具,它可以输出Linux所完成的几乎所有工作的数据。

pidstat主要用于监控全部或指定进程占用系统资源的情况

查看板载显示信息

[root@localhost ~]# dmidecode |grep -A 5 "On Board Device Information"
On Board Device Information
Type: Video
Status: Enabled
Description:  AST2050 VGA
