    Summary of Amazon Elastic Compute Cloud (EC2) Amazon Elastic Block Store (EBS) Snapshot pattern-based discovery

    The Amazon Elastic Compute Cloud (EC2) and Elastic Block Store (EBS) Snapshot pattern-based discovery enables the identification and mapping of AWS services within your cloud environment. To utilize this functionality, ensure you have the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

    Key Features

    • Prerequisites: Verify AWS discovery prerequisites and ensure relevant resources are not listed in the Resource Inclusion List to prevent duplicates.
    • Pattern Activation: The service pattern is disabled by default. After version 6.28.0, activating or deactivating patterns will not be considered a customization, allowing them to receive updates.
    • Discovery Schedule for GovCloud: For AWS GovCloud accounts, use a datacenter URL when creating an AWS service account.
    • Data Population: The discovery application populates data in the CMDB, including details about EBS snapshots such as Object ID, Name, State, and Size.

    Key Outcomes

    Using this discovery pattern, customers can effectively manage AWS EBS snapshots, ensure accurate data representation in the CMDB, and maintain up-to-date information on resource states and relationships. This process supports better visibility and service mapping within cloud environments, contributing to improved operational 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 - Elastic Compute Cloud EBS Snapshot - Extended Inventory (LP) pattern.

    Table 1. Storage Volume Snapshot [cmdb_ci_storage_vol_snapshot]
    Field Description
    Object ID [object_id] The Amazon Resource Name (ARN) uniquely identifying the EBS Snapshot.

    The ARN consists of the AWS region, account ID, and snapshot ID in the following format: arn:aws:ec2:<region>:<accountId>:snapshot/<snapshot_id>.
    Name [name] The unique identifier for the EC2 snapshot.
    State [state] The current state of the snapshot. For example: pending or completed.
    Install Status [install_status] Install status of the resource. Default value is Installed.
    Encrypted [is_encrypted] Indicates whether the snapshot is encrypted.
    Operational status [operational_status] Operational status of the resource. Default value is Operational.
    Description [short_description] Type of resource. The value is set to AWS::Elastic Compute Cloud::EBS Snapshot.
    Size (GB) [size] The size of the resource expressed in gigabytes (GB).
    Size bytes [size_bytes] The size of the snapshot in bytes.
    Volume Name [volume_name] The identifier of the volume associated with the snapshot.

    CI relationships

    The Amazon AWS - Elastic Compute Cloud EBS Snapshot - Extended Inventory (LP) pattern creates these relationships to support Amazon EC2 Amazon EBS Snapshot discovery.

    CI Relationship CI
    Storage Volume Snapshot [cmdb_ci_storage_vol_snapshot] Hosted on::Hosts AWS Datacenter [cmdb_ci_aws_datacenter]

    AWS tag discovery

    The pattern collects tags and populates them in the Key Value [cmdb_key_value] table.
    Table 2. Key Value [cmdb_key_value]
    Field Description
    Key [key] Tag name.
    Value [value] Tag value.
