I am working on a request to limit the number of CIs in the CMDB. Today, when discovery runs, it will discover (for example) an IP Router CI, along with its Network Adapters. The request I received is to prevent instances of cmdb_ci_network_adapter from being created.
The requestor has provided a list of 23 classes they want to see populated and all other classes should be ignored. Some of the desired classes include:
- Windows Server
- UNIX Server
- Linux Server
- Printer
- IP Router
- IP Switch
- ESX Server
Some of the classes they want to block, include:
- Print Queue
- VMware vCenter Server Object
- File System
- Tracked Configuration file
- Network Adapter
I know that I can delete the identification rules for the "undesired" classes, but I worry that they will be automatically re-created during a future update. Is there a better way to prevent Discovery from creating CIs in most classes?
