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

    The Google Cloud Platform (GCP) - Memorystore DB pattern in ServiceNow Discovery and Service Mapping enables automated discovery of Memorystore for Memcached and Memorystore for Redis resources during horizontal discovery. This pattern populates the Configuration Management Database (CMDB) with detailed information about these resources, their configurations, and relationships within a GCP environment.

    To utilize this pattern effectively, customers should ensure they meet the prerequisites outlined in the GCP discovery documentation and update to the latest Discovery and Service Mapping Patterns application from the ServiceNow Store if necessary.

    Key Features

    • CI Classes Introduced:
      • cmdbciclouddbcluster: Represents Memorystore clusters, extending the Cluster class.
      • cmdbciclouddatabase: Represents individual Memorystore database instances.
      • Existing classes such as Cloud Service Account, Availability Zone, and Google Datacenter are also populated with relevant data.
    • Data Collected: The pattern collects key attributes including project account details, datacenter and availability zone information, cluster characteristics (e.g., cluster ID, status, node count, IAM authentication, deletion protection), and database instance details (e.g., object ID, type, IP address, fully qualified domain name, operational status).
    • Tag Discovery: Tags associated with Memorystore instances are collected and stored in the Key Value table, enabling enhanced filtering and categorization within the CMDB.
    • CI Relationships: The pattern establishes critical relationships such as:
      • Databases hosted on datacenters and availability zones
      • Replication links between database instances
      • Clusters hosted on datacenters
      • Containment relationships between datacenters and availability zones
      • Cloud service accounts hosting datacenters
    • Visualization: Discovered Memorystore resources and their dependencies can be viewed on the Dependency Views map, providing a visual representation of resource relationships within the customer’s GCP environment.

    Practical Benefits for ServiceNow Customers

    • Automated and accurate discovery of GCP Memorystore resources enhances CMDB completeness and reliability.
    • Improved visibility into the configuration, operational status, and relationships of Redis and Memcached instances supports better incident, change, and asset management.
    • Tag collection enables efficient filtering and reporting on Memorystore resources based on customer-defined attributes.
    • Dependency views assist in impact analysis and service mapping by visually linking Memorystore clusters and instances to their underlying infrastructure.
    • Supports compliance and governance by tracking configurations such as IAM authentication and deletion protection settings.

    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.
