    Summary of Customizing the content in your Network Inventory Workspace widgets

    The Network Inventory Workspace in ServiceNow provides a set of standard widgets on the landing page displaying telecommunications network inventory data. Customers can customize the content of these widgets to show additional or different Network Inventory data by modifying the underlying CMDB groups that the widgets use for data collection.

    Standard CMDB Groups and Naming Conventions

    The widgets retrieve data using predefined CMDB groups organized by network domains and data type. The primary network domain selectors include:

    • Core Network – Core telecom equipment
    • Mobility Network – Mobile telecom equipment
    • Telco Network – General telecom equipment
    • All – Combined data across all network domains

    The CMDB group names combine the domain with specific data descriptors such as equipment status (e.g., Available, Pending Repair) or manufacturer (e.g., Ericsson, Nokia). For example, Core Available Status Equipment reports available equipment in the Core domain, while All Ericsson Manufacturer Equipment reports Ericsson equipment across all domains.

    Customizing Widget Content

    To change the data shown in widgets, such as the "Network equipment by manufacturer" pie chart, customers must create or modify CMDB groups using the standard naming conventions. This involves using the CMDB Groups function to define new group codes or adjust existing query conditions.

    For example, to add a new manufacturer like Dell to the manufacturer widget, you replicate the existing CMDB group patterns used for a manufacturer like Ericsson, tailoring them for Dell across each network domain (All, Core, Mobility, Telco).

    Practical Benefits for ServiceNow Customers

    • Flexibility: Customize Network Inventory Workspace widgets to reflect your organization's unique telecommunications assets and reporting needs.
    • Consistency: Use standardized CMDB group naming conventions to ensure proper data retrieval and widget functionality.
    • Control: Modify or extend the inventory data visible on landing page widgets without altering the base system code.

    Next Steps

    Customers should use the CMDB Groups function to create or update group codes following the documented naming conventions. For more detailed procedures on data collection, refresh, and CMDB group management, customers can refer to the related ServiceNow documentation on Network Inventory Workspace and CMDB groups.

    The Network Inventory Workspace is delivered in the base system with a standard set of information in each landing page widget. You can easily customize this content to include other Telecommunications Network Inventory data.

    Standard CMDB groups and naming conventions for Network Inventory Workspace widget data

    The data collection process for the Network Inventory Workspace landing page uses a standard CMDB group structure to retrieve data that appears in its widgets, including:
    • Network sites overview
    • Network entities by category
    • Network equipment by manufacturer
    • Network equipment by states

    For example, the following shows a listing of some of the CMDB groups that are used for the Network Inventory Workspace data collection:

    Figure 1. Standard CMDB groups for the Network Inventory Workspace

    Note:
    To learn how the data collection process operates, see Data collection and refresh for the Network Inventory Workspace widgets.
    These CMDB groups follow the following standard naming convention:
    1. The first segment represents the assigned domain for the network sites and entities. You use the Network domain selector in the Network Inventory Workspace to filter the data that appears by selecting one of the following types of network domains:
      Core
      Network domain for the core telecom equipment.
      Mobility
      Network domain for the mobile telecom equipment.
      Telco
      Network domain for the telecom equipment in general.
      All
      All equipment network domains that are combined into a single one for reporting purposes.
    2. The remaining segments represent a specific type of field data. For example:
      Available Status Equipment
      Reports the Available status for the equipment.
      Pending Repair Status Equipment
      Reports the Pending Repair status for the equipment.
      Ericsson Manufacturer Equipment
      Reports the percentage of the total equipment that is supplied by Ericsson.
      Nokia Manufacturer Equipment
      Reports the percentage of the total equipment that is supplied by Nokia.
    The following examples show how the name segments are combined in the CMDB groups to report the data that appears in the widgets in the Network Inventory Workspace:
    All Available Status Equipment
    CMDB group data that is used in the Network equipment by states widget to report the percentage of equipment that is in the Available status in all network domains.
    Core Available Status Equipment
    CMDB group data used in the Network equipment by states widget to report the percentage of equipment that is in an Available status in the Core network domain.
    Mobility Pending Repair Status Equipment
    CMDB group data used in the Network equipment by states widget to report the percentage of equipment that is in a Pending Repair status in the Mobility network domain.
    All Ericsson Manufacturer Equipment
    CMDB group data that is used in the Network equipment by manufacturer widget to report the total piece count for the equipment that is supplied by Ericsson in all network domains.
    Telecom Nokia Manufacturer Equipment
    CMDB group data that is used in the Network equipment by manufacturer widget to report the total piece count for the equipment that is supplied by Nokia in the Telecom network domain.

    Modifying the Network equipment by manufacturer widget

    This widget contains a pie chart with a standard set of the five most recognizable telecommunications equipment manufacturers.

    A pre-defined CMDB group structure supports retrieval of the data that appears in the widget pie chart. The following example shows the standard CMDB groups that are used to retrieve the manufacturer data for the Network Inventory Workspace.
    Figure 3. Standard CMDB groups used for the Network equipment by manufacturer widget

    To add or change the data in a widget, use the CMDB Groups function to create CMDB group codes or modify the accompanying query conditions for existing ones. To update any of the existing CMDB groups, you must follow the standard CMDB group naming convention used for the Network Inventory Workspace widgets.
    Note:
    To learn more about creating, updating, or naming CMDB groups, see CMDB groups.

    For example, let's say that you want to add another equipment manufacturer to the widget. To accomplish this task, you can use existing CMDB groups for a manufacturer, for each of the network domains, as the base for the new manufacturer. In this example, you use the existing CMDB groups for Ericsson as the base for the CMDB groups that you create for the new manufacturer.

    This table shows what the existing CMDB group codes look like for Ericsson, and what they look like when you create the CMDB group codes for Dell.
    Table 1. CMDB group example
    Existing CMDB Group Existing CMDB Group
    All Ericsson Manufacturer Equipment All Dell Manufacturer Equipment
    Core Ericsson Manufacturer Equipment Core Dell Manufacturer Equipment
    Mobility Ericsson Manufacturer Equipment Mobility Dell Manufacturer Equipment
