This process helps populate and maintain accurate data in the Configuration Management Database (CMDB) regarding Auto Scaling groups and their associated virtual machine instances. To leverage this feature fully, customers must ensure they have the latest Discovery and Service Mapping Patterns application installed, starting from version 1.0.95, which supports automatic collection of Auto Scaling tags. Show full answer Show less ## Prerequisites * **AWS Credentials Configuration:** Configure AWS Credentials of type "AWS Credentials" on your ServiceNow instance and set them to Active for authentication. * **AWS Service Account Setup:** Create and configure a valid AWS service account within ServiceNow. * **User Permissions:** Assign permissions to execute the AWS API call `DescribeAutoScalingGroups` to enable discovery of Auto Scaling groups. * **Cloud Discovery Schedule:** Create and configure a Cloud application schedule specifically to discover AWS Auto Scaling groups. * **Verify Instance Scale Set Table:** Ensure relevant fields like desired capacity, min/max size, and health check type are properly configured in the `cmdbciinstancescaleset` table. * **REST API Permissions:** Reference the Cloud Discovery patterns spreadsheet to grant necessary user permissions and stay updated with quarterly pattern releases. ## Key Features * **Data Collection:** The discovery process populates key fields in the CMDB, including Auto Scaling group names (ARNs), install and operational statuses, and size configurations (desired, min, max capacity) in the Instance Scale Set \[cmdbciinstancescaleset\] table. * **Virtual Machine Instances:** Captures VM instance IDs and associates them with Auto Scaling groups. * **Relationship Mapping:** Automatically creates and updates relationships between AWS Datacenter, Service Accounts, Instance Scale Sets, and VM Instances to reflect management and hosting structures accurately. Notably, starting in version 1.29.0, the relationship between Instance Scale Set and VM Instance changed from "Members::Member of" to "Managed by::Manages." * **Tag Discovery:** Auto Scaling group tags are collected and stored in the Key Value \[cmdbkeyvalue\] table, linking tag keys and values back to the respective Instance Scale Set CIs for enhanced metadata tracking. ## Practical Benefits for ServiceNow Customers * Automates discovery and CMDB population of AWS Auto Scaling groups and their instances, improving asset visibility and management. * Ensures accurate operational and capacity data is available for cloud infrastructure planning and monitoring. * Facilitates relationship mapping between cloud resources, enhancing dependency tracking and impact analysis. * Supports tag-based metadata collection, enabling better categorization and filtering of cloud resources in ServiceNow. * Integrates with Cloud Discovery scheduling, allowing flexible and regular updates to cloud environment data. The ® Discovery application uses the Amazon AWS - AutoScaling Groups (LP) pattern and Auto Scaling extensions to find AWS Auto Scaling groups. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store. Starting with Discovery and Service Mapping Patterns version 1.0.95, the pattern extension is automatically displayed and collects the Auto Scaling tags. ## Request apps on the Store {#aws-auto-scaling-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-auto-scaling-discovery__inline-send-to-store} ## Prerequisites {#aws-auto-scaling-discovery__section_prj_nrr_v5b} Configure AWS Credentials : On your instance, configure credentials of type AWS Credentials and set them to Active. 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."). Configure a 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.") Configure user permissions to execute the list AWS Auto Scaling groups API call : Provide the user permission to run the following API: https://autoscaling.amazonaws.com/?Action=DescribeAutoScalingGroups\&Version=2011-01-01 : 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.") Configure Cloud Discovery schedule : Create a cloud application schedule for discovering AWS Auto Scaling groups and configure the attributes. Set Discovery to Cloud application. 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.") Configure AWS Auto Scaling groups : Navigate to the Instance Scale Set table and verify that the configurations are set as follows: : {#aws-auto-scaling-discovery__table_ftg_qhp_w5b__entry__4} | Element Name | Type | Label | Max Length | |-|-|-|-| | desired_capacity | integer | Desired Capacity | 32 | | min_size | integer | Minimum Size | 32 | | max_size | integer | Maximum Size | 32 | | health_check_type | string | Health Check Type | 128 | [Table 1. Verify fields for table- \[cmdb_ci_instance_scale_set\]] {#aws-auto-scaling-discovery__table_ftg_qhp_w5b} ## Verify the REST API Permissions {#aws-auto-scaling-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-auto-scaling-discovery__cloud-discovery-api-paragraph} Note: You can test the AWS REST APIs using Postman API platform.
