    Summary of CMDB CI Class Models Store App

    The CMDB CI Class Models store app enhances the Configuration Management Database (CMDB) by adding out-of-the-box class models that extend the CMDB class hierarchy. These class models include details such as class descriptions, identification rules, and dependent relationships, enabling applications like Discovery and Service Mapping to effectively populate Configuration Items (CIs) and discover various technologies.

    Key Features

    • Class Extensions: The app introduces new classes, columns, and associated metadata in CMDB tables, enhancing the data structure.
    • Discovery Support: It provides extension classes for discovering a variety of software and technologies, including load balancers and virtualization tools.
    • Integration Options: Related applications and services, such as Service Graph Connectors, facilitate importing and integrating third-party data into CMDB classes.

    Key Outcomes

    After successful installation, users can verify added classes through the CI Class Manager. This ensures that the CMDB remains robust and functional. It is crucial to note that uninstalling the app could compromise the CMDB's integrity, leading to unexpected behaviors.

    The Configuration Management Database (CMDB) contains out-of-the-box classes that store data about Configuration Items (CIs). The CMDB CI Class Models store app adds class models that extend the CMDB class hierarchy, including class descriptions, identification rules, identifier entries, and dependent relationships if applicable.

    You can use the added classes as any other CMDB class. Applications such as Discovery and Service Mapping can use these class extensions to populate CIs and discover various technologies and software.
