    Summary of AWS MemoryDB for Redis

    The Discovery application in ServiceNow utilizes AWS MemoryDB for Redis patterns to locate AWS MemoryDB resources. To fully discover these resources, the Discovery and Service Mapping Patterns application must be installed from the ServiceNow Store. Customers should refer to the ServiceNow Store for app availability and cumulative release notes.

    Prerequisites

    • Configured AWS Credentials: Set up AWS Credentials on your ServiceNow instance.
    • Configured Cloud Service Account: Establish a valid AWS service account in ServiceNow.
    • User Permissions: Ensure that user permissions are granted to execute specific AWS MemoryDB API calls.
    • Cloud Discovery Schedule: Create a schedule for discovering AWS datacenters, ensuring Discovery is set to Cloud discovery.
    • REST API Permissions: Download the Cloud Discovery patterns spreadsheet to manage user permissions and access necessary information on patterns.

    Data Collected During Discovery

    During the horizontal discovery of AWS MemoryDB for Redis, key data fields collected include:

    • Main CI: Information on each node and its attributes such as ARN, Name, FQDN, and TCP Port.
    • Database Cluster: Data on the cluster's ARN, Name, FQDN, and TCP Port.

    Key Outcomes

    By following these procedures, ServiceNow customers can efficiently discover and manage AWS MemoryDB for Redis resources, enhancing their IT operations visibility and ensuring effective resource management.

    The ® Discovery application uses the AWS MemoryDB for Redis pattern and extensions to find AWS MemoryDB for Redis. Discovering some of these resources requires installing the Discovery and Service Mapping Patterns application from the ® Store.

    Request apps on the Store

    Visit the ServiceNow Store website to view all the available apps and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the ServiceNow Store version history release notes.

    Prerequisites

    Configured AWS Credentials
    On your instance, configure credentials of type AWS Credentials. For more information, see Access setup for AWS service accounts.
    Configured Cloud service account
    Configure the AWS service account valid in the ServiceNow instance. For more information, see Set up AWS service accounts.
    Configured user permissions to execute the list AWS MemoryDB for Redis API calls
    Provide the user permission to run the following API:
    • https://memory-db.{region}.amazonaws.com?Action=DescribeClusters&ShowShardDetails=true
    • https://memory-db.{region}.amazonaws.com? Action=ListTags&ResourceArn={arn}
    For more information, see Amazon AWS Cloud components discovery using patterns.
    Configured Cloud Discovery schedule
    Create a cloud application schedule for discovering AWS datacenters. Set Discovery to Cloud discovery. For more information, see: Create schedules for discovering cloud resources in Cloud Discovery Workspace

    Verify the REST API Permissions

    Download the Cloud Discovery patterns spreadsheet so you can grant user permissions required for running the Discovery patterns. In addition to permissions, the spreadsheet also includes useful information such as pattern names, types, CI Classes, and links to vendor documentation. New patterns are available quarterly, so check periodically to be sure you have the latest version of the spreadsheet.

    Note:
    You can test the AWS REST APIs using Postman API platform. For more information, see the How to test AWS REST API using POSTMAN [KB0782183] article in the Now Support Knowledge Base.
