linux应用--硬件信息查看
真乱---整理下、、、
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 --------------------------------------------------
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 -------------------------------------------------- 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 | grep -i 'VGA' --------------------------------------------------
8, 声卡信息 --------------------------------------------------
1)lspci |grep -i 'VGA' 2)dmesg | grep -i 'VGA' --------------------------------------------------
9, 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
10, 需要手动安装的工具 lshw,hwinfo,hal-device-manager
Solaris如何检测硬件参数 俺从别处发现了些有意思的东西：
Solaris的硬件相关命令
1)．查看当前处理器的类型和速度(主频)
# psrinfo –v
Status of processor 1 as of: 11/24/01 10:34:41 Processor has been on-line since 11/24/01 10:18:20. The sparcv9 processor operates at 432 MHz, and has a sparcv9 floating point processor. Status of processor 3 as of: 11/24/01 10:34:41 Processor has been on-line since 11/24/01 10:18:22. The sparcv9 processor operates at 432 MHz, and has a sparcv9 floating point processor.
2)．打印当前的OBP版本号
# prtconf –V
OBP 3.20.0 2000/10/24 10:47
# /usr/platform/sun4u/sbin/prtdiag –v | grep OBP
OBP 3.20.0 2000/10/24 10:47 POST 6.1.0 2000/10/24 10:49 ok. .version Release 3.20 Version 0 created 2000/10/24 10:47 OBP 3.20.0 2000/10/24 10:47 POST 6.1.0 2000/10/24 10:49 OBDIAG 4.5.1 2000/10/24 10:48
3)．查看硬盘物理信息(vendor, RPM, Capacity)
# iostat –E
sd0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: SEAGATE Product: ST34371W SUN4.2G Revision: 7462 Serial No: JDX394220KW EBC Size: 4.29GB <4292075520 bytes>; Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 sd2 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: FUJITSU Product: MAJ3364M SUN36G Revision: 0804 Serial No: 01M18144 Size: 36.42GB <36418595328 bytes>; Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 sd3 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: FUJITSU Product: MAJ3364M SUN36G Revision: 0804 Serial No: 01M16199 Size: 36.42GB <36418595328 bytes>; Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 sd21 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: TOSHIBA Product: DVD-ROM SD-M1401 Revision: 1007 Serial No: 06/22/00 Size: 18446744073.71GB <-1 bytes>; Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0
4)．查看磁盘的几何参数和分区信息
# prtvtoc
/dev/rdsk/c0t0d0s0 * /dev/rdsk/c0t0d0s0 partition map * * Dimensions: * 512 bytes/sector * 135 sectors/track * 16 tracks/cylinder * 2160 sectors/cylinder * 3882 cylinders * 3880 accessible cylinders * * Flags: * 1: unmountable * 10: read-only * * Unallocated space: * First Sector Last * Sector Count Sector * 8277120 103680 8380799 * * First Sector Last * Partition Tag Flags Sector Count Sector Mount Directory 0 2 00 0 2049840 2049839 / 1 3 01 2049840 615600 2665439 2 5 00 0 8380800 8380799 5 0 00 2665440 2458080 5123519 /opt 6 4 00 5123520 3073680 8197199 /usr 7 8 00 8197200 79920 8277119 /export/home
5)．显示已经使用和未使用的i-node数目
# df –F ufs –o i
Filesystem iused ifree %iused Mounted on /dev/dsk/c0t0d0s0 7859 479821 2% / /dev/dsk/c0t0d0s6 37763 339517 10% /usr /dev/dsk/c0t0d0s5 722 301102 0% /opt /dev/dsk/c0t0d0s7 4 24380 0% /export/home
6).显示cpu使用率最高的进程
# ps –eo pid,pcpu,args | sort +1n
该命令输出当前系统进程的pid, CPU占用率及命令描述，并以pcpu来排序
7)．显示内存占用率最高的进程
# ps –eo pid,vsz,args | sort +1n
该命令输出当前系统进程的pid，内存占用率及命令描述，并以vsz来排序
8)．查看及启动系统的32位或64位内核模式 64位模式
# isalist –v
sparcv9+vis sparcv9 sparcv8plus+vis sparcv8plus sparcv8 sparcv8-fsmuld sparcv7 sparc
# isainfo –v

11)．测定当前的显示器刷新频率
/usr/sbin/ffbconfig –rev
Valid values for -res option are: 1024x768x60 [1] 1024x768x70 [1] 1024x768x75 [1] [2] 1024x768x77 1024x800x84 1152x900x66 1152x900x76 1280x800x76 [1] [2] 1280x1024x60 [1] [2] 1280x1024x67 1280x1024x76 1280x1024x85 [1] [2] 960x680x112s 960x680x108s 640x480x60 [1] [2] 640x480x60i [1] 768x575x50i [1] 1440x900x76 [1] [2] 1600x1000x66 [1] [2] 1600x1000x76 [1] [2] 1600x1280x76 [1] [2] 1920x1080x72 [1] [2] 1920x1080x76 [1] [2] 1920x1200x70 [1] [2] 1920x1200x75 [1] [2] svga [1] 1152 1280 stereo vga [1] [2] ntsc [1] pal [1] none Notes: [1] monitor does not support this resolution. [2] this version of FFB (FFB1) does not support this resolution
12)．查看系统配置
# /usr/platform/sun4u/sbin/prtdiag –v

ps：做系统移植的时候，非常有用。网卡芯片什么的，驱动也好移植。
