    Summary of Amazon DynamoDB Cluster pattern-based discovery

    The Amazon DynamoDB Cluster pattern-based discovery enables ServiceNow customers to identify and map Amazon DynamoDB clusters and their nodes within their AWS cloud environments. This functionality is part of the Discovery and Service Mapping Patterns application, which must be up to date to discover AWS resources accurately. It supports detailed inventory collection and updates the Configuration Management Database (CMDB) with relevant cluster and node information.

    Key Features

    • Pattern Activation: The DynamoDB Cluster discovery pattern is disabled by default and must be enabled. With Visibility Content version 6.28.0 and later, enabling or disabling patterns will not count as customization, allowing patterns to update automatically after upgrades while preserving activation status.
    • AWS Prerequisites: Customers must verify AWS discovery prerequisites and ensure that DynamoDB resources are not listed in the Resource Inclusion List to prevent duplicate discoveries.
    • GovCloud Support: Discovery of AWS GovCloud (US) accounts requires configuring the discovery schedule with the appropriate datacenter URL for the AWS service account.
    • CMDB Data Population: The pattern populates detailed DynamoDB cluster and node data into specific CMDB tables:
      • Cloud DataBase Cluster [cmdbciclouddbcluster]: Stores cluster-level information such as name, ARN, status, type, endpoint, node count, and vendor.
      • Cluster Node [cmdbciclusternode]: Stores node-level details including node ID, status, endpoint, and links to the parent cluster.
      • Key Value [cmdbkeyvalue]: Captures AWS tags associated with the clusters and nodes for enhanced identification and filtering.
    • CI Relationships: The pattern establishes relationships between clusters, nodes, and AWS datacenters to provide a comprehensive topology view within the CMDB.

    Key Outcomes

    • Accurate discovery and mapping of Amazon DynamoDB clusters and nodes within the ServiceNow CMDB.
    • Improved visibility into the operational status and configuration of DynamoDB resources.
    • Support for AWS GovCloud environments ensuring broader cloud coverage.
    • Structured and linked data enables better impact analysis, compliance, and cloud asset management.

    Discovery and Service Mapping Patterns finds AWS services 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.

    Pattern-based discovery and mapping requirements

    Verify the AWS discovery prerequisites
    For more information, see the prerequisites section in AWS discovery using patterns.
    Remove resources from the Resource Inclusion List table
    Verify that the relevant resource isn't listed in the Resource Inclusion List [sa_cloud_inventory_resource_whitelist] table to avoid duplicate discovery. For more information on removing resources from the Resource Inclusion List, see AWS Resource Inventory discovery with Patterns.
    Enable the relevant pattern
    The pattern for this service is disabled by default. Starting with Visibility Content version 6.28.0, activating or deactivating a pattern won't be considered a customization, and it will continue to receive updates. Patterns that were previously activated or deactivated will reset to the latest predefined version after upgrading while retaining the last active field value. For more information on enabling patterns, see Activate a disabled pattern.
    Configure the Discovery schedule to support GovCloud
    Discovering AWS GovCloud (US) accounts requires using a datacenter URL when setting up an AWS service account. For more information, see Create AWS service accounts.

    Data stored in CMDB tables

    Discovery and Service Mapping Patterns application populates data in the CMDB when running the Amazon AWS - DynamoDB Cluster - Extended Inventory (LP) pattern.

    Table 1. Cloud DataBase Cluster [cmdb_ci_cloud_db_cluster]
    Field Description
    Name [name] The name assigned to the DynamoDB Accelerator (DAX) cluster.
    Cluster ID [cluster_id] The Amazon Resource Name (ARN) uniquely identifying the DAX cluster.
    Cluster Status [cluster_status] The current operational status of the DAX cluster.
    Cluster Type [cluster_type] Cluster type: DynamoDB Cluster.
    Fully qualified domain name [fqdn] The endpoint address used to connect to the DAX cluster.
    Install Status [install_status] Install status of the resource. Default value is Installed.
    Node Count [node_count] The total number of nodes in the DAX cluster.
    Operational status [operational_status] Operational status of the resource. Default value is Operational.
    Description [short_description] Description of the cluster: DynamoDB Cluster.
    Vendor [vendor] Name of the vendor: Amazon.
    Table 2. Cluster Node [cmdb_ci_cluster_node]
    Field Description
    Name [name] The unique identifier of the DAX node within the cluster.
    Serial Number [serial_number] Unique identifier of the node in the following format: <cluster_arn>/node/<node_id>.
    Node Status [node_status] The current operational status of the node. For example: available, joining, or deleting.
    Fully qualified domain name [fqdn] The endpoint address used to connect to the specific DAX node.
    Install Status [install_status] Install status of the node. Default value is Installed.
    Operational Status [operational_status] Operational status of the node. Default value is Operational.
    Cluster [cluster] References the Cloud Database Cluster [cmdb_ci_cloud_db_cluster] table.
    Description [short_description] Description of the node: DynamoDB Cluster Node.

    CI relationships

    The Amazon AWS - DynamoDB Cluster - Extended Inventory (LP) pattern creates these relationships to support Amazon DynamoDB Cluster discovery.

    CI Relationship CI
    Cloud DataBase Cluster [cmdb_ci_cloud_db_cluster] Hosted on::Hosts AWS Datacenter [cmdb_ci_aws_datacenter]
    Cluster Node [cmdb_ci_cluster_node] Hosted on::Hosts AWS Datacenter [cmdb_ci_aws_datacenter]

    Cluster Node [cmdb_ci_cluster_node] References Cloud DataBase Cluster [cmdb_ci_cloud_db_cluster]

    AWS tag discovery

    The pattern collects tags and populates them in the Key Value [cmdb_key_value] table.
    Table 3. Key Value [cmdb_key_value]
    Field Description
    Key [key] Tag name.
    Value [value] Tag value.
