通过SNMP检索硬件信息

本文介绍了通过SNMP检索硬件信息的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试从一系列设备中检索硬件信息，到目前为止，我使用了带有以下OID 1.3.6.1.2.1.25.3.2.1 的snmpget / snmpwalk。它返回的信息很少，例如，如果我是从Windows操作系统在计算机上运行的，则会得到以下CPU：

I am trying to retrieve hardware informations from a series of devices, so far I used snmpget/snmpwalk with the following OID 1.3.6.1.2.1.25.3.2.1 but it returns very few informations, for example if I run this on my computer from a Windows OS I get those CPUs:

未知处理器

Unknown Processor

未知处理器

未知处理器

未知处理器

相反，如果我从Debian运行命令，则会得到正确的值：

Instead if I run the command from Debian I get the correct value:

正品Intel：Intel（R）CoreTM i3 CPU M 330 @ 2.13GHz

Genuine Intel: Intel(R) Core(TM) i3 CPU M 330 @ 2.13GHz

猜测有一个浮点协处理器

Guessing that there's a floating point co-processor

我了解Windows和Linux以完全不同的方式填充MIB，但就其本身而言，它们的机器人似乎完全忘记了其他诸如视频卡或鼠标/键盘之类的设备。 Windows可以正确显示键盘，Linux则不能。他们两个都根本不显示视频卡和声卡。问题是否与我必须设置的某些选项有关？

I understand that Windows and Linux fill MIBs in a completely different way but, for istance, bot of them seem to completely forget about other devices such as video card or mouse/keyboard. Windows shows the keyboard correctly, Linux does not. Both of them don't show video card and sound card at all. Is the problem related to some options I have to set?

如果我想获取更多信息（例如CPU频率）怎么办？

And what if I want to obtain MORE informations such as CPU frequency?

推荐答案

上面OID所在的HOST-RESOURCES-MIB实际上将描述有关系统硬件的大量信息。但是：

The HOST-RESOURCES-MIB, which is where the above OID lies, will in deed describe a fair amount about the hardware on the system. But:

系统确实需要支持它。您已经证明Windows SNMP代理显然没有列出正确的内容，并且功能已损坏。

即使在Linux上，也没有列出系统中的每个组件，因为MIB

对于Linux案例，您不应该列出这些类型的组件或未编写使它起作用的代码。

For the linux case, you could always go work on the code and submit patches back to the original package (which for linux is certainly the Net-SNMP package).

还有ENTITY-MIB，其目的是更好地模拟系统的硬件，但我不知道linux（或Windows）

There is also the ENTITY-MIB which is designed to model a system's hardware better, but I don't know of linux (or windows) support for it.

最后，如果未返回正确的结果，则始终可以在Windows计算机上运行其他SNMP代理。 IE，我听说过（但我自己不使用Windows），与本地SNMP代理相比，Net-SNMP代理在Windows上提供了优越的功能。

Finally, you could always run a different SNMP agent on the windows machine if it's not returning the right result. IE, I have heard (but don't use windows myself) that the Net-SNMP agent provides superior functionality on windows compared to the native SNMP agent.
