Hardware Asset Management licensing
Summarize
Summary of Hardware Asset Management licensing
Hardware Asset Management (HAM) licensing allows you to select specific resource categories to use, enabling cost savings by paying only for the categories you actively manage. Only opted-in resource categories contribute toward your Subscription Units, which determine licensing costs based on the number and type of assets you manage.

Each physical asset in the Asset [almasset] table counts toward your subscription if it belongs to an opted-in category and is in an active state. The licensing is independent of CMDB CI classes or records.
Resource Categories and Subscription Units
The HAM license divides assets into resource categories, each with a predefined subscription unit ratio representing how many assets correspond to one subscription unit. For example, four End User Computers equal one subscription unit, while one Server equals one subscription unit.
- End User Computers: 4 assets per unit
- Servers: 1 asset per unit
- Network Gear: 5 assets per unit
- Mobile Devices: 10 assets per unit
- Telecom Network Inventory: 1 asset per unit (requires Telecom Network Inventory application)
- Monitors: 15 assets per unit (available from HAM version 10.1.0 and license version 5.0)
- Storage: 3 assets per unit (available from HAM version 10.1.0 and license version 5.0)
- Printers: 10 assets per unit (available from HAM version 10.1.0 and license version 5.0)
- Unclassified Hardware: 1 asset per unit (available from HAM version 10.1.0 and license version 5.0)
Resource categories are linked to specific entitlements, which you can configure using the snhamactiveentitlements system property on on-premise instances.
Opt-In Requirements and Usage
Normalization functions and asset actions only operate for resource categories you have opted into. You must explicitly opt in to use these capabilities for a category.
Assets are counted toward subscription units regardless of assignment to users, as long as they are active and belong to opted-in categories.
Custom Model Categories
Custom model categories you create are licensed only if:
- The custom category falls under the hierarchy of an opted-in model category.
- The parent category is associated with an opted-in, licensable resource category.
The snhamp.enablecustomcategorylicensing system property controls whether custom categories require opt-in licensing (default is false). When enabled, only custom categories under opted-in parents have access to HAM features and workflows.
Important Version and Upgrade Notes
- From HAM version 10.1.0 and license version 5.0 onward, Printers, Monitors, Storage, and Unclassified Hardware categories require opt-in for feature access and licensing.
- Upgrading to license version 5.0 requires explicitly opting in these categories to maintain feature access for existing assets.
- Telecommunications Network Inventory integration requires installing the respective application and opting in to that resource category.
- Assets in model categories that are children of opted-out resource categories or certain categories (e.g., Printers, Storage) are excluded from HAM features unless opted in as per newer versions.
Practical Implications for ServiceNow Customers
By managing your HAM license opt-in settings, you control which asset categories count toward your subscription cost and which categories have full HAM functionality. Proper configuration ensures compliance, cost efficiency, and access to HAM capabilities such as normalization and asset actions.
Review your organization’s asset categories and opt-in only for those actively managed to optimize licensing costs. When upgrading HAM versions, especially to version 10.1.0 or license version 5.0, ensure you explicitly opt in to newly licensable categories to retain functionality.
Hardware Asset Management (HAM) licensing enables you to choose the Hardware Asset Management resource categories that you want to use. You can save money by paying only for those categories that you use, and not for categories that you don't use.
Every physical asset record in the Asset [alm_asset] table counts toward your subscription total if it meets the following criteria:
- It belongs to a resource category your organization has opted in to for HAM licensing.
- It is in an active state (not Disposed or Retired).
Assignment to a user is not required — an unassigned asset that meets these criteria counts the same as an assigned asset.
HAM licensing has no dependency on CMDB CI classes or CI records.
Based on the usage of model categories, the ServiceNow HAM license is divided into resource categories. There are different types of resource categories. Different assets fall under different categories as well. Make sure you opt in the correct and required categories. An asset represented in the Asset [alm_asset] table and which meets the criteria for each managed IT resource type such as Server, End User Computers, Network Gear, and Mobile Device, is counted toward a Subscription Unit based on the predefined ratio of number of assets to subscription units.
The comma separated entitlements should be updated in the following format:
- End User Computers- ham_computer_license
- Mobile Device- ham_mobiledevice_license
- Servers- ham_server_license
- Network Gear- ham_networkgear_license
- Monitors- ham_monitor_license
- Storage- ham_storage_license
- Printer- ham_printer_license
- Telecom Network Inventory- ham_tni_license
| Resource category | Subscription unit ratio | Model category |
|---|---|---|
| End User Computers | 4:1 | Computer |
| Servers | 1:1 | Any server such as the following:
|
| Network Gear | 5:1 |
|
| Mobile Device | 10:1 | Mobile Device |
| Telecom Network Inventory | 1:1 |
|
| Unclassified hardware | 1:1 | Hardware |
| Monitors | 15:1 | Monitor |
| Storage | 3:1 | Storage Device |
| Printers | 10:1 | Printer |
To access Hardware Asset Management features for Telecommunications Network Inventory, you should install the Telecommunications Network Inventory application and opt-in to the Telecom Network Inventory resource category. For more information, see Telecommunications Network Inventory integration with Hardware Asset Management.
HAM Licensing for custom model categories
- The custom model category of the asset belongs to the hierarchy of opted-in model categories.
- The parent model category of a custom model category is associated with a licensable and opted-in resource category.
You can enable HAM licensing for custom model categories by using the sn_hamp.enable_custom_category_licensing system property. By default, the value of this system property is set to false. When you set the sn_hamp.enable_custom_category_licensing system property to true, custom model category assets are excluded from HAM workflows unless the parent of the custom model category is an opted-in and licensable category.
- When you opt in Computers, both Laptop and Tablet are also counted toward a Subscription Unit under the End User Computers resource category. Also, these custom model categories can access Hardware Asset Management features and workflows.
- When you opt out Computers, both Laptop and Tablet are also opted-out and these custom model categories can’t access Hardware Asset Management features and workflows.
- Any model category that is a child of an opted-out resource category.
- Any model category that is a child of model categories such as printer and storage device. This exclusion is only in Hardware Asset Management version 10.0.0.Note:In Hardware Asset Management version 10.0.0 and earlier, assets with model categories such as Printer, Consumables, and Storage Device retain access to Hardware Asset Management features without opting in a resource category.
From Hardware Asset Management version 10.1.0 onward, the resource categories like Printers, Monitors, Storage, and Unclassified hardware are licensed and available only when you upgrade to HAM license version 5.0. You must opt in these resource categories to access the Hardware Asset Management features. When you opt in these resource categories, all their child model categories can also access the HAM features and workflows.
After you upgrade to HAM license version 5.0, the printers, monitors, storage devices, and Unclassified hardware assets that were created in the earlier versions wouldn't be able to access the Hardware Asset Management features by default. You should explicitly opt in these resource categories.
- Any other custom model category without a parent category.
