Building an Oracle Management Pack for OpsMgr Cross-Platform Agents, Part 3

Continuing on with the development of a management pack for monitoring Oracle database servers on a UNIX/Linux platform (part 1, part 2), I will describe in this post some of the characteristics and methodology of the class structure and object discoveries. 

Class Structure

To start the class structure, I defined a few arbitrary abstract classes to function as the base classes for Oracle objects:  OracleSCX.OracleSubsystem, OracleSCX.OracleApplication, and OracleSCX.OracleComponent.  Subsequently, I created a set of classes to represent the Oracle objects and components that would be discovered.  This class hierarchy is best illustrated with this image:

As for the object relationships, the discovered objects are organized as follows:

• Oracle SCX Server
  • Oracle SCX Listeners      
    • Oracle SCX Listener
  • Oracle SCX Instance
    • Oracle SCX TableSpaces
      • Oracle SCX TableSpace
        • Oracle SCX Data File
    • Oracle SCX Processes
      • Oracle SCX Process
    • Oracle SCX Databases
      • Oracle SCX Database
    • Oracle SCX Alert Logs

A diagram view of a discovered Oracle system illustrates these relationships:
