如何使用PHP从远程服务器获取MIB列表?

问题描述

我正在从事一个涉及SNMP的项目.基本上，我需要在PHP中构造MIB和OID树.

I am working on a project that involves SNMP. Basically I need to construct MIB and OID tree in PHP.

我知道已经有一些程序可以执行此操作，但是我正在尝试实现自己的版本以与我的Web应用程序结合.

I know that there are programs that do this already, but I am trying to implement my own version to incorporate with my webapp.

我所知道的:我熟悉php SNMP功能.我可以使用SNMPWALk来获取OID等.不幸的是，据我所知没有找到所有MIB并将其解析的函数.

What I know: I am familiar with php SNMP function. I can do SNMPWALk to get OIDs and such. Unfortunately there is no function that I know of that finds all MIBs and parses them.

我需要的:首先从远程服务器获取所有MIB文档，然后根据每个文档获取其对象.最后，我的树将具有以下结构:

What I need:Get all MIB docs first from remote server, then based on each docs get their Objects.At the end my tree will have this structure:

+ mib-doc1 |
           - obc1
           - obj2
+ mib-doc2 |
           - obj1
           - obj2
           - obj3

以此类推...

我也知道:

1. 从实际服务器上，我可以获取所有MIB目录:

1. 我还可以获得所有MIB文档的列表:

我有2个问题.

1. 如何从远程服务器获取所有MIB文档的列表?
2. 是否有更简单的方法(具有已知功能)来解析每个MIB以获取对象?

谢谢

推荐答案

如果只需要模块列表，请参见如果，您的管理器支持SNMPv2-MIB :: sysORTable.这当然不能帮助您找到MIB文件，但是会告诉您应该支持什么.

If you just want a list of modules, see if your manager supports SNMPv2-MIB::sysORTable. This does not help you find the MIB files of course, but tells you what is supposed to be supported.

报价规格，sysORTable为:

这是我获得的标准Linux主机的信息:

Here is what I get for a standard Linux host :

snmptable -M +.  -m +ALL -v 2c -c public -Pu -Ci  <some ipaddr>  SNMPv2-MIB::sysORTable
SNMP table: SNMPv2-MIB::sysORTable

 index                                        sysORID                                              sysORDescr  sysORUpTime
