服务器查看GPU等信息

lspci，顾名思义，就是显示所有的pci设备信息。pci是一种总线，而通过pci总线连接的设备就是pci设备了。如今，我们常用的设备很多都是采用pci总线了，如：网卡、存储。

如果没有lspci命令，安装：

1	apt-get install pciutils

查看gpu：

1	lspci \| grep -i vga

这样就可以显示机器上的显卡信息，比如

[root@localhost conf]# lspci | grep -i vga
01:00.0 VGA compatible controller: nVidia Corporation Device 1081 (rev a1)
02:00.0 VGA compatible controller: nVidia Corporation GT215 [GeForce GT 240] (rev a2)
08:05.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 10)

如果想看详细的信息，比如 GeForce GT 240，即 02:00.0

[root@localhost conf]# lspci -v -s 02:00.0
02:00.0 VGA compatible controller: nVidia Corporation GT215 [GeForce GT 240] (rev a2) (prog-if 00 [VGA controller])

可以看到GT240的显存是 256M

如果没有安装显卡驱动，显示可能如下：

root@0765afb5370d:/# lspci  | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Device 3e92
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1c82 (rev a1)
root@0765afb5370d:/# lspci  | grep -i 01:00.0
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1c82 (rev a1)

        Memory at f0000000 (64-bit, prefetchable) [size=32M]
        I/O ports at e000 [size=128]
        Expansion ROM at f7000000 [disabled] [size=512K]
        Capabilities: <access denied>
        Kernel driver in use: nouveau
lspci: Unable to load libkmod resources: error -12

查看nvidia的gpu信息

1	nvidia-smi

配合watch命令, 让一秒刷新一次

1	watch -n 1 nvidia-smi

查看内存及cpu使用情况的命令

top

htop工具，更直观

1	apt-get install htop

安装完后，直接输入命令

htop

就可以看到内存或cpu的使用情况了。
