This capability helps populate the Configuration Management Database (CMDB) with detailed information about MemoryDB clusters and nodes. Show full answer Show less To utilize this feature effectively, ensure you have the latest Discovery and Service Mapping Patterns application from the ServiceNow Store, as pattern updates are released quarterly. ## Prerequisites * **AWS Credentials:** Configure AWS service account credentials in your ServiceNow instance to authenticate AWS API calls. * **User Permissions:** Grant the necessary permissions to execute AWS MemoryDB for Redis API calls, specifically for describing clusters and listing tags. * **Cloud Discovery Schedule:** Set up a cloud application schedule with Discovery mode set to Cloud Discovery to automate resource discovery. * **REST API Permissions Verification:** Use the Cloud Discovery patterns spreadsheet to verify and assign required user permissions, and test AWS REST APIs via tools like Postman. ## Data Collected During Discovery When running the AWS MemoryDB pattern, the following key data is collected and stored in the CMDB: * **Cloud DataBase \[cmdbciclouddatabase\]:** Details about individual nodes, including Amazon Resource Name (ARN), node name, fully qualified domain name (FQDN), TCP port, and database type (set as memorydb). * **Cloud DataBase Cluster \[cmdbciclouddbcluster\]:** Details about the overall cluster, including ARN, cluster name, FQDN, and TCP port. ## CI Relationships and References The discovery patterns establish relationships to model the AWS MemoryDB environment accurately: * Clusters are linked to their constituent nodes (Cluster of::Cluster). * Clusters are hosted on AWS Datacenters. * References connect configuration items without creating explicit relationships in the CI Relationship table. ## AWS Tag Discovery The pattern also collects AWS tags associated with MemoryDB clusters and stores them in the **Key Value \[cmdbkeyvalue\]** table. Tags are linked to their corresponding Cloud DataBase Cluster records, enabling enhanced filtering, reporting, and management based on AWS tagging. ## Practical Benefits for ServiceNow Customers * Automated and accurate discovery of AWS MemoryDB for Redis resources enhances CMDB completeness and accuracy. * Visibility into cluster and node configurations supports better operational management and troubleshooting. * Tag collection enables alignment with AWS governance and cost management strategies. * Establishing relationships between clusters, nodes, and datacenters supports impact analysis and service mapping. The ® Discovery application uses the Amazon AWS MemoryDB pattern and extensions to find AWS MemoryDB for Redis. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store. ## Request apps on the Store {#aws-memorydb-discovery__id_i2h_mj1_bvb} Visit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) 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](https://www.servicenow.com/docs/r/store-release-notes/sn-store-release-notes.html).{#aws-memorydb-discovery__inline-send-to-store} ## Prerequisites {#aws-memorydb-discovery__section_prj_nrr_v5b} Configured AWS Credentials : On your instance, configure credentials of type AWS Credentials. For more information, see [Access setup for AWS service accounts](https://servicenow-prod.fluidtopics.net/u50K4wELxZMtjj~alXnzVg "Cloud Discovery and Cloud Provisioning and Governance need access to resources in the Amazon Web Services (AWS) service accounts. Learn about different methods of configuring such access."). Configured Cloud service account : Configure the AWS service account valid in the ServiceNow instance. For more information, see [Set up AWS service accounts.](https://servicenow-prod.fluidtopics.net/UO4WIwvrPVWckI9LeWzMRg "Create and configure cloud service accounts at ServiceNow AI Platform for the corresponding Amazon Web Services (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} {#aws-memorydb-discovery__ul_wjd_gmr_svb} : For more information, see [Amazon AWS Cloud components discovery using patterns.](https://servicenow-prod.fluidtopics.net/nnBwzYmMo_kpTZpG3y5~xQ "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud deployment during horizontal discovery. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.") 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](https://servicenow-prod.fluidtopics.net/4egAp8rafm6~FSeRVUzHTg "Create schedules for discovering cloud resources based on the discovery method that you choose: service accounts or IP ranges. The discovery schedule defines the various settings for the cloud discovery.") ## Verify the REST API Permissions {#aws-memorydb-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.{#aws-memorydb-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 during AWS MemoryDB for Redis horizontal discovery {#aws-memorydb-discovery__section_md4_mqh_w5b} Discovery populates the data in the CMDB when running the Amazon AWS MemoryDB pattern. {#aws-memorydb-discovery__table_olj_wwb_x5b__entry__2} | Field | Description | |-|-| | Object ID \[object_id\] | The Amazon Resource Name of a single node in the cluster. | | Name \[name\] | The name of a single node in the cluster. | | Fully qualified domain name \[fqdn\] | The Fully Qualified Domain Name of each node in the cluster. | | TCP port(s) \[tcp_port\] | The TCP port that a single node in the cluster is getting traffic from. | | Type \[type\] | The type of database.
