基于ITM 6.1的Compaq/DEC Tru64 系统监控的Universal Agent实现

该solution使用ITM 6.1 Universal Agent进行Compaq/DEC Tru64 操作系统的健康状况监控。
它能够提供以下内容的监控：
1、Compaq/DEC Tru64系统buffer caches的正确、错误采样。
2、CPU当前负载
3、虚拟内存与swap交换分区
4、文件系统使用情况
5、当前活动进程
6、当前活动用户
7、系统内存使用情况
8、各个硬件传感器的探测：风扇、电源、电压、温度

ITM 6.1 Universal Agent能够在支持UA的系统平台上远程监控目标系统Tru64 OS，使用SNMP v1方式。

该solution工作在在ITM 6.1和OMEGAMON 技术框架下，它能够运行在不同的系统平台的Universal Agent下，包括Windows, AIX, Solaris, HP/UX, and Linux. 

安装过程：
1、确保你的Universal Agent环境的系统SNMP协议以安装并激活。
2、如果未安装了SNMP，请在安装完成后重新启动Universal Agent。
3、导入元数据compaq_tru64.mdl，该mdl文件位于<install dir>/tmaitm6/metafiles directory
4、导入方法：
 windows:使用命令行：kumpcon import compaq_tru64.mdl
 unix:使用命令行：bin/kumpcon import compat_tru64.mdl或者直接在um控制台运行import命令。
5、一旦你成功导入元数据文件，接下来你必须启动monitoring并且配置SNMP设置。
 （1）在已经启动的UA上，登录到UA tree，鼠标右键选择“Monitor Start”
 （2）填写2个字段（主机名，循环时间）
 以上操作是默认的假设SNMP community为public方式，如果你使用自定义的其他community，请修改：
  [1]在登录入口重新填写“hostname community”
  或者：
  [2]在当前工作目录中编辑KUMSMIBI ，改变默认public为你自定义的community名称。
 （3）然后选择适当的目的文件，比如：TRU6400。
6、、一旦Universal Agent已经启动并运行，你就能够自定义监控问题及场景。
  
  
该解决方案的核心是：compaq_tru64.mdl 文件

该文件的实现源代码由三个mib文件组成。
标准MIB都是以RFC文档的形式发布的，RFC文档虽然是纯文本格式，但是它有页眉和页脚的信息，在包含MIB定义的文档里面通常还有一些说明性的文字，这个脚本就是把这些MIB文件不需要的信息去除，生成MIB文件。
MIB文件有自己的语法格式，称作ASN.1格式，部分编辑器支持这种格式。对于不同的功能/模块，MIB也不相同，于是IETF就制定了一个又一个的MIB文件，这些MIB定义也以RFC文档的格式发布，但是以这种格式发布的MIB文件不能直接通过编译器的编译，需要把中间的MIB定义抽取出来。

svrSystem.mib
svrMgt.mib
pm.mib
