    Summary of Google Cloud Platform (GCP) Cloud components discovery using Patterns

    This feature leverages Discovery and Service Mapping Patterns to identify and map Google Cloud Platform (GCP) components during horizontal discovery within ServiceNow. It requires up-to-date applications and specific configurations to ensure comprehensive and accurate cloud resource discovery and integration into the CMDB.

    Prerequisites

    • Application Versions: Ensure Discovery and Service Mapping Patterns (≥1.8.0), CMDB CI Class Models (≥1.49.0), and Visibility Content (≥6.13.0) are current as of September 2023.
    • MID Server Requirements: Use a dedicated MID Server for cloud discovery with at least 16 cores, 8 GB RAM, and 4 GB JVM memory. The MID Server must have internet access and be properly configured according to ServiceNow guidelines.
    • Google Cloud BigQuery and Bigtable: Enable the property snitompattern.googledbservicetablecollection in MID Server properties to allow discovery of these services.
    • User Roles: Assign the Google Cloud Platform member the "Viewer" role in the GCP IAM console to permit necessary read access.

    Configuration Steps

    • Google API Credentials: Configure API credentials appropriately to enable cloud discovery operations.
    • GCP Service Account: Create a service account with required permissions for discovery activities.
    • Cloud Logging Events: Enable collection of cloud logging events via Google Cloud Logging to auto-update the CMDB based on native API events.
    • CI Relationships: Activate CI relationships related to tag-based discovery introduced in ServiceNow Store release 1.0.68 to incorporate discovered components into service instances.
    • Discovery Schedule: Configure a Discovery schedule in the Discovery Admin Workspace to automate GCP discovery.
    • Optional Performance Improvement: From version 1.30.2 onwards, populate Service Account and Logical Datacenter fields directly in cloud CIs to enhance query performance.

    Additional Resources

    • Download the Cloud Discovery patterns spreadsheet to understand required user permissions, pattern details, CI classes, and vendor documentation links.
    • Check quarterly for new patterns to keep discovery capabilities current.

    This comprehensive setup ensures ServiceNow customers can efficiently discover, map, and maintain GCP cloud components within their CMDB, enabling better visibility, service mapping, and operational insight into their cloud environments.

    Discovery and Service Mapping Patterns uses patterns to discover components of the Google Cloud Platform (GCP) deployment during horizontal discovery. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Request apps on the Store

    Visit the ServiceNow Store website to view all the available apps and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the ServiceNow Store version history release notes.

    Prerequisites

    Verify that the applications are up to date.
    • Discovery and Service Mapping Patterns starting version 1.8.0 (September 2023)
    • CMDB CI Class Models starting version 1.49.0 (September 2023)
    • Visibility Content starting version 6.13.0 (September 2023)
    Verify the MID Server requirements
    • Use a dedicated MID Server for cloud discovery. The MID Server must have 16 Cores, 8 GB with 4 GB Java Virtual Machine (JVM) memory allocation. For information on verifying MID Server specifications, see KB article KB2156327.
    • Deploy and connect the dedicated MID Server with internet access.
    • For more information on the MID Server configurations, see Install and configure MID Servers to access cloud environments.
    Verify Google Cloud BigQuery and Google Cloud Bigtable requirements
    To discover Google Cloud BigQuery and Google Cloud Bigtable, navigate to All > Discovery > MID Server > Properties and ensure that the sn_itom_pattern.google_dbservice_table_collection property is set to True.
    Verify user role settings

    Set the user permission for the Google Cloud Platform member to Viewer:

    1. In the Google Cloud Platform console, navigate to IAM.
    2. Select the relevant member from the list and click the Edit icon.
    3. In the Edit permissions window, select Viewer from the Role list.
    4. Click Save.
    Configure Google API Credentials
    For more information, see Configure the Google API credentials for Cloud Discovery.
    Create a Google Cloud Platform service account
    For more information, see Create GCP service accounts.
    Enable collecting cloud logging events
    The Google Cloud Platform patterns can collect cloud logging events generated by the native Google Cloud APIs. Configure the Google Cloud Logging service to auto-update the CMDB.
    Activate the cloud-related CI relationships
    To include discovered components into service instances, enable CI relationships used in tag-based discovery by Service Mapping. These CI relationships are available from the 1.0.68 release on the ServiceNow Store. For operational steps, see Tag-based discovery configuration.
    Verify that a Discovery schedule is configured
    For more information, see Create a GCP Discovery schedule in Discovery Admin Workspace.
    (Optional) Populate Service Account and Logical Datacenter fields in cloud CIs
    Starting with Discovery and Service Mapping Patterns version 1.30.2, you can improve query performance by populating Service Account and Logical Datacenter fields directly in cloud CIs. For more information, see Improved query performance with direct field population in CI tables.

    Verify the REST API Permissions

    Download the Cloud Discovery patterns spreadsheet so you can grant user permissions required for running the Discovery patterns. In addition to permissions, the spreadsheet also includes useful information such as pattern names, types, CI Classes, and links to vendor documentation. New patterns are available quarterly, so check periodically to be sure you have the latest version of the spreadsheet.
