    Summary of AWS Systems Manager Parameter Store pattern-based discovery

    The AWS Systems Manager Parameter Store pattern-based discovery enables ServiceNow customers to discover and map AWS Systems Manager Parameter Store parameters within their cloud environments using the Discovery and Service Mapping Patterns application. This discovery process populates relevant data into both CMDB and non-CMDB tables, improving visibility and management of AWS parameter store resources.

    Key Features

    • Pattern Activation: The pattern for this service is disabled by default and must be enabled to start discovery. From Visibility Content version 6.28.0 onward, enabling or disabling patterns is no longer treated as customization, ensuring patterns remain updated after upgrades.
    • Avoiding Duplicate Discovery: Customers should verify that AWS Systems Manager Parameter Store resources are not listed in the Resource Inclusion List table (sacloudinventoryresourcewhitelist) to prevent duplicates.
    • Data Populated in Tables:
      • Non-CMDB tables: The application populates data in specific non-CMDB AWS tables when running the Amazon AWS - Systems Manager Parameter Store - Extended Inventory (LP) pattern. This includes details such as parameter name, ARN, type, and version.
      • CMDB tables: Data about the parameters is stored in the cmdbcicmpresource table, capturing resource type (set as AWS::SystemsManager::ParameterStore), install status, operational status, and other key attributes.
    • CI Relationships and References: The discovery pattern establishes relationships such as "Hosted on" between the parameter store resources and AWS datacenters. References link parameter store entries to their corresponding cloud resource records.
    • AWS Tag Discovery: Tags associated with parameters are collected and stored in the cmdbkeyvalue table, linking tag names and values to the relevant cloud resource records.

    Practical Considerations for ServiceNow Customers

    • Ensure AWS discovery prerequisites are met by reviewing the Amazon AWS Cloud components discovery prerequisites.
    • Activate the AWS Systems Manager Parameter Store discovery pattern to enable data collection.
    • Check and manage the Resource Inclusion List to prevent duplicate entries.
    • Use the populated CMDB and non-CMDB tables to view detailed parameter store information and their AWS tags.
    • Leverage the CI relationships to understand resource hosting and dependencies within your AWS infrastructure.

    Discovery and Service Mapping Patterns finds AWS Systems Manager Parameter Store parameters 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.

    Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables.

    Data stored in non-CMDB tables

    Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Amazon AWS - Systems Manager Parameter Store - Extended Inventory (LP) pattern.

    You can review the non-CMDB AWS tables by navigating to All > Configuration > AWS. You can also search the navigation filter for the specific pattern name.

    Table 1. AWS Systems Manager Parameter Store [cmdb_aws_systems_manager_parameter_store]
    Field Description
    Name [name] Name of the parameter.
    Object ID [object_id] The Amazon Resource Name (ARN) of the parameter.
    Type [type] The type of the parameter. The value is String, StringList, or SecureString.
    Version [version] The version number of the parameter.
    Configuration Item [configuration_item] References the Cloud Resource [cmdb_ci_cmp_resource] table.

    Data stored in CMDB tables

    Discovery and Service Mapping Patterns application populates data in the CMDB when running the Amazon AWS - Systems Manager Parameter Store - Extended Inventory (LP) pattern.

    Table 2. Cloud Resource [cmdb_ci_cmp_resource]
    Field Description
    Name [name] Name of the parameter.
    Object ID [object_id] The ARN of the parameter.
    Resource type [resource_type] Type of resource. The value is set to AWS::SystemsManager::ParameterStore.
    Install Status [install_status] Install status of the resource. Default value is Installed.
    Operational status [operational_status] Operational status of the resource. Default value is Operational.

    CI relationships

    The Amazon AWS - Systems Manager Parameter Store - Extended Inventory (LP) pattern creates the following relationships and references to support AWS Systems Manager Parameter Store discovery. References link to records in other tables and don't appear in the CI Relationship [cmdb_rel_ci] table.

    Table 3. CI relationships
    CI Relationship CI
    Cloud Resource [cmdb_ci_cmp_resource] Hosted on::Hosts AWS Datacenter [cmdb_ci_aws_datacenter]
    Table 4. CI references
    CI Field Referenced CI
    AWS Systems Manager Parameter Store [cmdb_aws_systems_manager_parameter_store] Configuration Item [configuration_item] Cloud Resource [cmdb_ci_cmp_resource]
    Key Value [cmdb_key_value] Configuration item [configuration_item] Cloud Resource [cmdb_ci_cmp_resource]

    AWS Tag discovery

    The Amazon AWS - Systems Manager Parameter Store - Extended Inventory (LP) pattern collects tags and populates them in the Key Value [cmdb_key_value] table.

    Table 5. Key Value [cmdb_key_value]
    Field Description
    Key [key] Tag name.
    Value [value] Tag value.
    Configuration item [configuration_item] References the Cloud Resource [cmdb_ci_cmp_resource] table.
