    Summary of Amazon DynamoDB Cluster pattern-based discovery

    The Amazon DynamoDB Cluster pattern-based discovery in ServiceNow enables automated detection and mapping of DynamoDB clusters within your AWS cloud environment. This capability is part of the Discovery and Service Mapping Patterns application and requires the latest version for optimal functionality. It helps maintain an accurate Configuration Management Database (CMDB) by populating detailed cluster and node data.

    Key Features

    • Pattern Activation: The DynamoDB Cluster discovery pattern is disabled by default and must be enabled explicitly. Starting with Visibility Content 6.28.0, pattern activation or deactivation is no longer a customization and updates are preserved after upgrades.
    • Discovery Prerequisites: AWS discovery prerequisites must be met, including ensuring that the relevant resources are not listed in the Resource Inclusion List table to avoid duplicate entries.
    • GovCloud Support: Discovery of AWS GovCloud (US) requires configuring discovery schedules with appropriate datacenter URLs and AWS service accounts.
    • CMDB Data Population: When the Amazon AWS - DynamoDB Cluster - Extended Inventory (LP) pattern runs, it populates detailed information on DynamoDB clusters and nodes into CMDB tables, including:
      • Cloud DataBase Cluster [cmdbciclouddbcluster]: Captures cluster name, ARN, status, type, endpoint, node count, vendor, and operational status.
      • Cluster Node [cmdbciclusternode]: Captures node identifiers, status, endpoint, and links to the parent cluster.
    • CI Relationships: The pattern creates relationships linking clusters and nodes to AWS datacenters, supporting comprehensive service mapping.
    • AWS Tag Discovery: Tags from AWS resources are collected and stored in the Key Value [cmdbkeyvalue] table to enhance resource metadata.

    Practical Benefits for ServiceNow Customers

    • Automates the discovery and CMDB population of Amazon DynamoDB clusters and their nodes, ensuring accurate and up-to-date asset records.
    • Improves visibility into AWS DynamoDB environments, including operational status and configuration details.
    • Supports governance and compliance by avoiding duplicate resource discovery through Resource Inclusion List management.
    • Enables better cloud service mapping and relationship tracking, critical for impact analysis and change management.
    • Facilitates discovery in AWS GovCloud environments with appropriate configuration.

    By leveraging this pattern-based discovery, ServiceNow customers can efficiently manage their DynamoDB resources in the CMDB, streamline cloud operations, and maintain comprehensive service visibility across AWS environments.

    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 Amazon AWS Cloud components 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 Amazon Web Services (AWS) Resource Inventory.
    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] Cluster of::Cluster Cloud DataBase Cluster [cmdb_ci_cloud_db_cluster]
    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]
