How many classes are in the estate?
On the demo estate — the synthetic Vantrex environment, 313 devices across four discovery sources — records land in ten ServiceNow CI classes: cmdb_ci_laptop, cmdb_ci_computer, cmdb_ci_desktop, cmdb_ci_mobile_device, cmdb_ci_linux_server, cmdb_ci_vm_instance, cmdb_ci_ip_switch, cmdb_ci_ip_router, cmdb_ci_ip_firewall and cmdb_ci_wap_network. Laptops dominate, as you would expect of an end-user estate.
A further 78 records sit in a review bucket rather than in any class. Those are records where classification did not reach a confident answer, and the system holds them for a person instead of forcing them into the nearest class. That is deliberate: an ambiguous device surfaced for review is a decision waiting to be made; the same device quietly filed under cmdb_ci_computer is a wrong record nobody will find.
The number is not a property of the product. The estate’s 44 governed classification rules target exactly those ten classes, so the class set is a consequence of the rules in force — and changing a rule is a recorded decision, with an author and an authority, not an edit. Your own estate would produce a different set, shaped by your sources and your rules.
