The ServiceNow®
Discovery application uses the Amazon OpenSearch discovery pattern
to find Amazon OpenSearch service domains.
OpenSearch is an open-source search and analytics engine for use cases such as log
analytics, real-time application monitoring, and clickstream analysis. OpenSearch operates
as a cluster of nodes that are abstracted from the end user. An OpenSearch service domain is
synonymous with an OpenSearch cluster. Domains are clusters with settings, instance types,
instance counts, and storage resources.

## Prerequisites {#amazon-opensearch-discovery__section_gww_fqb_b5b4}

* Install the Discovery and Service Mapping Patterns application from the ServiceNow Store.
* Configure an AWS Service Account with valid credentials on the ServiceNow instance with permission to run the following APIs:
  * https://es.{region}.amazonaws.com/2021-01-01/domain
  * https://es.{region}.amazonaws.com/2021-01-01/opernsearch/domain-info{"DomainNames":\[\]}
  * https://tagging.{region}.amazonaws.com {"ResourceTypeFilters":\[\]}

## Verify the REST API Permissions {#amazon-opensearch-discovery__id_ysv_22b_f1c}

Download the [Cloud Discovery patterns spreadsheet](https://downloads.docs.servicenow.com/resource/enus/api/servicenow-discovery-patterns-api-details.xlsx) 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.{#amazon-opensearch-discovery__cloud-discovery-api-paragraph}
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 \[KB0782183\]](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0782183) article in the Now Support Knowledge Base.

## Data collected by Discovery during horizontal discovery {#amazon-opensearch-discovery__section_tkw_4rb_b5b}

table.
