    Summary of GCP Spanner Pattern-Based Discovery

    The GCP Spanner pattern-based discovery identifies GCP Spanner instances and databases within your cloud environment. To ensure optimal functionality, it may be necessary to update the Discovery and Service Mapping Patterns application from the ServiceNow Store to the latest version.

    Key Features

    • Discovery Requirements: Confirm that prerequisites for GCP discovery are met as outlined in the Google Cloud Platform (GCP) Cloud discovery using Patterns section.
    • Data Population: The discovery process collects data and populates the Configuration Management Database (CMDB) with relevant information about GCP resources, including cloud service accounts, availability zones, datacenters, and databases.
    • CI Relationships: The GCP - Spanner DB pattern establishes relationships between various configuration items (CIs) such as Google Datacenters, Availability Zones, Cloud Databases, and Databases.
    • Tag Discovery: Tags associated with GCP resources are collected and stored in the Key Value table, enhancing resource identification and management.

    Key Outcomes

    By implementing the GCP Spanner pattern-based discovery, you can effectively monitor and manage your GCP Spanner resources, ensuring accurate data representation in the CMDB. This capability supports improved resource management and operational efficiencies in your cloud environment.

    Discovery and Service Mapping Patterns finds GCP Spanner instances and databases on your cloud environment. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Type [type] The type of database.
    Install Status [install_status] Install status of the resource. Default value is Installed.

    CI relationships

    The Google Cloud Platform (GCP) - Spanner DB pattern creates these relationships to support GCP Spanner discovery.

    CI Relationship CI
    Google Datacenter [cmdb_ci_google_datacenter] Contains::Contained by Availability Zone [cmdb_ci_availability_zone]
    Google Datacenter [cmdb_ci_google_datacenter] Hosted on::Hosts Cloud Service Account [cmdb_ci_cloud_service_account]
    Cloud DataBase [cmdb_ci_cloud_database] Contains::Contained by Database [cmdb_ci_database]
    Cloud DataBase [cmdb_ci_cloud_database] Hosted on::Hosts Google Datacenter [cmdb_ci_google_datacenter]

    Key Value [cmdb_key_value] References Cloud DataBase [cmdb_ci_cloud_database]

    GCP Tag discovery

    The Google Cloud Platform (GCP) - Spanner DB pattern collects tags and populates them in the Key Value [cmdb_key_value] table.

    Table 6. Key Value [cmdb_key_value]
    Field Description
    Key [key] Tag name.
    Value [value] Tag value.
    Configuration item [configuration_item] References the Cloud DataBase [cmdb_ci_cloud_database] table.
