Number of UD license units required for SAM purposes

Hi Forum Members,

Let's assume I need AMX for SAM purposes specifically. I have a fully on-prem server environment, using VMware. Some VM's run Oracle DB (which is a must-have product to keep track of in SAM), but most of them do not. Some VM's run Windows Server OS, others run Linux.

CMS with enough UD licenses is required for this, so I have referred to https://docs.microfocus.com/doc/UCMDB/24.2/DscvrLicOvrvw.

The questions are the followings:

An Express Discovery (costing 0.1 unit) will detect the operating system, the underlying hardware (including CPU details) and the list of installed software on both Windows and Linux servers. Is that correct?

I use 10 VMware guests on a physical host. I assume a basic discovery provides the number of CPU's, OS's and the list of software products installed which should be enough for license calculation for some products like Windows Server and MS SQL, whether they are licensed on a per-OSI or per-CPU base. Does it consume 0.1 unit to calculate Windows Server or MS SQL license consumption for the VM's or do I need 1 unit per VM?

Again, 10 guests on a single host. I have Oracle DB installed on 2 VM"s from that 10 and using OLMS for license consumption calculation. How many UD license units do I need to plan with?

Is there any documentation about what discovery jobs are considered as Express or Advanced (Inventory/Full)? Is UD license unit consumption derived from the type of job or the same job can consume 0.1 or 1 unit depending on other factors?

Thanks for any input.
