    Summary of GCP Spanner Pattern-Based Discovery

    The GCP Spanner pattern-based discovery feature enables the identification and mapping of GCP Spanner instances and databases within your cloud environment. Updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store may be necessary for optimal functionality.

    Key Features

    • Data Collection: Discovery captures essential information during the horizontal discovery of GCP Spanner, populating the Configuration Management Database (CMDB) with relevant data.
    • CI Relationships: The GCP - Spanner DB pattern establishes relationships between various configuration items (CIs), such as Google Datacenter, Availability Zone, Cloud Database, and Cloud Service Account, to enhance visibility and management.
    • Tag Discovery: The discovery process collects tags associated with resources, storing them in the Key Value table for better organization and retrieval.

    Key Outcomes

    By utilizing the GCP Spanner pattern-based discovery, customers can expect to achieve:

    • A comprehensive view of their GCP Spanner resources in the CMDB.
    • Improved resource management through detailed CI relationships and tag organization.
    • Enhanced operational oversight of their cloud databases, ensuring resources are adequately monitored and maintained.

    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.

    Field Description
    Name [name] The name of the Spanner database.
    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.
