    Summary of Related Lists of CI components

    Related Lists in Configuration Item (CI) records within ServiceNow display additional components that are part of the CI, such as disk drives on servers or rules controlling network routers. These lists are dynamically populated based on the latest Discovery scan results, showing only the components detected during that scan. Components not found in the most recent scan are considered absent and do not appear in the lists.

    Key Features

    • Dynamic Component Display: Related Lists show components that are either CIs themselves (e.g., hard disks) or non-CI components (e.g., serial numbers, rules) associated with the CI.
    • Filtering Logic: Components that are CIs are filtered to exclude those with a status of "Absent," while non-CI components are filtered to exclude those marked as absent.
    • Discovery Integration: The Related Lists reflect the current state based on the latest Discovery scan, which may cause changes in the displayed components from scan to scan.
    • Icon Indicators: Various icons appear in the Related Lists to indicate the status of incidents, problems, changes, and outages related to the CI, such as currently active incidents, planned changes, or recently completed outages. These icons help quickly identify operational or maintenance activities impacting the CI.
    • Teams Related List: This feature associates user groups to a CI based on group type, facilitating flexible tracking of groups responsible for or related to a CI. It appears on CI forms for services and their descendant classes.

    Practical Application for ServiceNow Customers

    ServiceNow customers can leverage Related Lists to gain real-time visibility into the components that make up a CI and their current operational status as detected by Discovery. This enables better configuration management, impact analysis, and change planning by understanding the exact composition and state of a CI at any time. The icon indicators further assist in quickly assessing active or planned incidents, changes, or outages related to the CI, improving incident and change management workflows.

    Additional Concepts

    • Dependent CIs management
    • Principal Class
    • Related tasks such as creating, reclassifying, or deleting CI classes
    • Viewing and editing class definitions and metadata

    Related lists in CI records display additional components contained by that CI, such as disk drives on a server and the rules that control the behavior of a network router.

    When Discovery runs, the Related List is populated with the components that Discovery finds running on the CI. The CI record might show different lists from scan to scan, depending on whether or not Discovery found the component.

    By default, the Related Lists only display those components that are associated with that CI in the CMDB that has been discovered by the last scan. Components that are recorded in the CMDB but are not discovered in a scan, are deemed absent and do not appear in the list.

    There are two types of components that appear in the Related List: components that are CIs themselves (such as hard disks), and components that are not (serial numbers and rules). The default filter condition in the breadcrumbs for components that are CIs is [Status] [!=] [Absent]. The filter condition for components that are not CIs is [Absent] [=] [false].

    For example, a router can have several Related Lists affected by these filter conditions, including routing rules, disk drives, interfaces, and network adapters. Only those components found during the last Discovery appear in these Related Lists.

    Icons in related lists

    Any of the following icons may appear in lists of CI related items.
    Icon Description
    Currently active incidents For currently active incidents against this configuration item
    Currently active problems For currently active problems against the configuration item
    Currently active changes For currently active changes against the configuration item that are not covered in the past, current, pending changes. For example, a request to update the operating system on a server that is currently in progress may display this icon.
    Recently completed changes For changes that were recently completed against the configuration item. changes with an "Actual_end_date" in the past.
    Planned changes For changes that are planned soon against the configuration item. changes with an "Actual start date" in the future.
    Currently active changes For currently active changes against the configuration item that have an "Actual start date"
    Recently completed outages For outages that were recently completed against the configuration item. outages with an "end" date in the past.
    Planned outages For outages that are planned soon against the configuration item. outages with a "begin" date in the future.
    Currently active outages For currently active outages against the configuration item that have a "begin" date in the past and no "end" date
    Issues with downstream CI This will only show up in the Tree view and indicates that a configuration item that is downstream has at least one of the above issues against it.

    The system looks five calendar days into the past and seven calendar days into the future when looking at recent outages and changes.
