Configuration Item Types
Configuration Item types denote the classification of CIs into different categories. Any organization-specific entity, such as business services, workstations, servers, documents, and even the people working in your organization, can be considered a CI Type.
Each CI Type can be defined with specific attributes and relationships that are unique to the CIs classified under them. CIs can also be classified into subtypes (child CI types). For example, the CI Type Server can contain subtypes such as File Server, Application Server, Database Servers, etc.
To access CI types, go to Admin > Customization > CMDB > Configuration Item Types.
