snmp网络监控程序问题
最近公司有个项目，其中有一块要求如下：
以WEB方式监控平台运行情况
监控对象包括：
监控对象 说明
ApplicationProgram 记录应用程序运行状态
CPU 记录cpu使用情况
Database 记录数据库运行状态
Disk 记录硬盘使用情况
Memory 记录内存使用情况
Network 记录网络运行状态
Service 记录服务运行状态
TableSpace 记录表空间使用情况
leader说要用到了SNMP，这方面以前没接触过，最近开始猛啃，但还是没有好的思路，各位兄弟多多指点，先谢过了。

需要系统开 snmp 服务，
写个网关采集信息保存到数据库，web浏览数据库。
snmp采集可用 uk.co.westhawk.snmp 或者 snmp4j

感谢hut给的思路
我找个例子，各位帮我看看：

运行后：
我的开发环境是winxp ，我配置snmp服务，运行上面的程序： 
点击getnext按钮 在eclipse控制台显示结果如下：

如何解析上述的OID(对象标识符）和返回状态值，
如何获取：
ApplicationProgram 记录应用程序运行状态
CPU 记录cpu使用情况
Database 记录数据库运行状态
Disk 记录硬盘使用情况
Memory 记录内存使用情况
Network 记录网络运行状态
Service 记录服务运行状态
TableSpace 记录表空间使用情况
各位帮忙分析一下，我对这不太熟悉，非常谢谢
