AWS MemoryDB for Redis discovery with Patterns

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 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.

注:

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.
