    Summary of Google Cloud Platform (GCP) Memorystore discovery using patterns

    The Google Cloud Platform (GCP) - Memorystore DB pattern in ServiceNow Discovery and Service Mapping Patterns enables automated discovery of Memorystore for Memcached and Memorystore for Redis instances during horizontal discovery. This pattern requires the latest Discovery and Service Mapping Patterns application version and adherence to GCP discovery prerequisites.

    Key Features

    • Data Model Extension: Introduces a new CI class Cloud DataBase Cluster [cmdbciclouddbcluster] extending the existing Cluster [cmdbcicluster] class.
    • Discovery Data Population: Captures detailed attributes of Memorystore clusters and instances, including cluster ID, status, type, disk space, node count, IAM authentication, deletion protection, and asset tags.
    • Related CIs and Attributes: Discovers and populates related configuration items such as Cloud Service Accounts, Availability Zones, and Google Datacenters with relevant metadata (e.g., names, states, regions, object IDs).
    • Relationships and References: Establishes CI relationships to represent hosting, replication, containment, and hosting relationships among databases, clusters, datacenters, availability zones, and service accounts. References are maintained to support data integrity without cluttering relationship tables.
    • Tag Collection: Collects resource tags and stores them as key-value pairs linked to Cloud DataBase CIs, enabling enhanced categorization and filtering.
    • Dependency Visualization: Provides Dependency Views maps for visualizing Memorystore instances and clusters along with their relationships within the organization.

    Key Outcomes

    • ServiceNow customers gain comprehensive, up-to-date visibility into GCP Memorystore Redis and Memcached resources within their CMDB.
    • Enhanced operational and install status tracking of Memorystore clusters and instances aids in ongoing management and troubleshooting.
    • Clear mapping of relationships between Memorystore resources and their hosting infrastructure facilitates impact analysis and service mapping accuracy.
    • Tag discovery supports better organization and reporting based on custom labels assigned in GCP.
    • Visual dependency maps improve understanding of Memorystore resource topology, supporting effective decision-making and incident response.

    Discovery and Service Mapping Patterns uses the Google Cloud Platform (GCP) - Memorystore DB pattern to discover Memorystore for Memcached and Memorystore for Redis 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.
