How Servicenow calculates SAM Pro licenses

[MercBuilding]

Hello All,

     Just wanted to check how Servicenow calculates the number of licenses used by the customer for SAM Pro, is it based on role we give to the users or number of tables been utilized for that?

Thanks!

Hi,
It depends on the resource type subscription unit.

• Managed IT Resource Types-
  “Server” is any physical or virtual server that is represented as a configuration item (“CI”)
  in a CMDB table listed below and managed by the Software Asset Management
  application.
• “End User Computing Device” is any physical or virtual non-Server CI in a CMDB table
  listed below and managed by the Software Asset Management application.

“SaaS Subscription User” is any unique User Principal Name in the SaaS Subscription User
table listed below managed by the Software Asset Management application.
Servers and End User Computing Devices are managed by the Software Asset
Management application when the installed software on the Managed IT
Resources is represented in the cmdb_sam_sw_install table.

Each Managed IT Resource Type defined in Section 2.1 will be counted towards a
Subscription Unit based on a predefined ratio of Subscription Unit to Managed IT
Resource per the table below:

The above is for customers using the SKU for SAM Pro based on Subscription Units, there is an older SKU that some customers are still using which is based on a different metric Computer.  Talk to your ServiceNow account team if you aren't sure which one applies.

how i can manually check for SAM PRO ,as we have almost the double SU for end user compter like 100k SU and we purchased just 60k. So how i can manualy check if this calculation is done ok or something is wrongly calculated

Hi ,

You can manually validate the SU calculation, but first confirm what is actually being counted. The ITAM License Report shows the SU consumption, purchased SUs, and the Subscription Unit Ratio used for each resource type.

Go to All > ITAM Licensing > ITAM License Report and compare the End User Computing Device count with the SU consumption. Then reconcile the counted devices against 'cmdb_sam_sw_install', checking for duplicate, retired, test, or stale CIs. A device is generally counted when managed software on that device is represented in 'cmdb_sam_sw_install', and the platform converts the managed resource into SUs using the defined ratio.

The 100k SUs may not equal 100k computers. It can include EUC devices, servers, SaaS users, and other managed resources, each converted using a different ratio. So validate the EUC device count, apply the SU ratio from the report, and compare that result with the platform-calculated SUs.

More details can be found here: Subscriptions for Software Asset Management 

Hope this helps!

To look at raw data, export the cmdb_sam_sw_install table and group the installed_on devices by type (in relation to the SU definitions) and count the number of unique devices in each group.
