MiB browser design (source code)

MiB is the basis of the SNMP collector. MiB are the carrier of network OID descriptions. They mainly include the values, descriptions, and parameters of device OID into MiB. It is the main basic data used for active polling and passive collection of trap information translation. However, MIB is a special protocol that stores data through a special tree structure.

Establish a set of good MIB control code, the foundation of the entire network management system. If you use a flexible and scalable MIB library, it is the vitality of the sustainable development of a network management system.

Mibble-parser-2.9.2.jar is an open-source mibble parser, the code of this program is built for the mibble-parser-2.9.2.jar. And thanks to the fengjiangzhongf@gmail.com for writing part of the code for this module.

 Get all MIB Information

Package COM. shine. framework. mibbrowser; import Java. util. list; import COM. shine. framework. mibbrowser. model. mibmodel; public class allmiblogsexample {/*** get all OID information of the specified document ** @ Param ARGs */public static void main (string [] ARGs) {list <mibmodel> List = mibbrowserutils. getalloid ("E:/workspace/nms4.6/webcontent/WEB-INF/config/MIB/CISCO-PRODUCTS-MIB.mib"); For (mibmodel model: List) {system. out. println ("name:" + model. getname (); system. err. println ("detail:" + model. getdetail ());}}}

Obtains information about a specified oid.

Package COM. shine. framework. mibbrowser; import COM. shine. framework. mibbrowser. model. mibmodel; public class gettargetoidinfoexample {/*** get the information of the specified OID ** @ Param ARGs */public static void main (string [] ARGs) {mibmodel model = mibbrowserutils. getoidinfo ("E:/workspace/nms4.6/webcontent/WEB-INF/config/MIB/CISCO-PRODUCTS-MIB.mib", "1.3.6.1.4.1.9.1.67"); system. out. println (model. getname ());}}

In specific use, we regard MIB as a specific data storage instead of the original tree structure. Is the list structure.
