CMDB CI Class Models
Summarize
Summary of CMDB CI Class Models
The CMDB CI Class Models app extends the ServiceNow Configuration Management Database (CMDB) by adding specialized class models that enhance the base-system CMDB classes. These extensions include detailed class descriptions, identification rules, identifier entries, and dependent relationships, enabling more precise and comprehensive configuration item (CI) management.

This app is essential for customers who want to leverage enhanced CI class structures to improve discovery accuracy and service mapping by incorporating additional technologies and software into the CMDB.
Key Features
- Extended Class Hierarchy: Adds new classes, columns, and metadata to key CMDB tables such as CMDB Class Information, Identifier, Identifier Entry, and CMDB Metadata Hosting Rules.
- Identification and Dependency Management: Supports identification rules and dependent relationships to accurately classify and relate CIs.
- Compatibility with Discovery and Service Mapping: Enables Discovery and Service Mapping applications to utilize the extended classes for improved detection and population of CIs.
- Integration with Related Apps: Works alongside other ServiceNow Store apps like Discovery patterns and Service Graph Connectors for enhanced device and application discovery and third-party data integration.
Using the Classes
Customers can use these extended classes in the same way as native CMDB classes. This enables Discovery and Service Mapping to recognize additional technologies and software, facilitating richer and more accurate CMDB population.
Supported Software and Technologies
The app supports discovery of a variety of software and technologies through specific extension classes, including but not limited to:
- Avi Load Balancer (Avi Vantage)
- BYOL Model of RDS for Oracle
- Firewalls
- IBM Hardware Management Console (HMC) and Virtualization
- Internet of Things (IoT)
- Nutanix Acropolis
- OpenStack Resources
- Red Hat Virtualization (RHV)
- Transport Layer Security (TLS)
- VMware NSX Load Balancer and Advanced Load Balancer
Each of these technologies is supported by corresponding Discovery patterns that leverage the extended classes for accurate detection.
The CMDB contains base-system classes that store data about configuration items (CIs). The CMDB CI Class Models ServiceNow® Store app adds class models that extend the CMDB class hierarchy, including class descriptions, identification rules, identifier entries, and dependent relationships if applicable.
Classes added by the CMDB CI Class Models app
For the full list of added classes, see List of classes added by the CMDB CI Class Models app.
- CMDB Class Information [cmdb_class_info]: Class descriptions
- Identifier [cmdb_identifier]: Identification rules
- Identifier Entry [cmdb_identifier_entry]: Identification entries
- CMDB Metadata Hosting Rules [cmdb_metadata_hosting]: Dependent relationships
Using the classes
You can use the added classes like any other class. Applications such as Discovery and Service Mapping can use class extensions to populate CIs and to discover technologies and software.
- Configuration Management database: A collection of class diagrams and class attributes for key CMDB classes.
- CMDB tables descriptions: Descriptions of key CMDB tables in the base system.
- Populating the CMDB: Information about the various options for populating the CMDB.
- Discovery patterns: A ServiceNow Store app that provides a library of Discovery patterns for discovering specific devices and applications in the industry.
- Service Graph Connectors: ServiceNow Store apps that provide predefined integrations for importing and integrating common third-party data into CMDB classes. Also includes the IntegrationHub ETL wizard for creating new ETL transform maps.
