This functionality requires the latest version of the Discovery and Service Mapping Patterns application and supports data population in both CMDB and non-CMDB tables. Show full answer Show less ## Key Features * **AWS Discovery Prerequisites:** Customers must verify AWS discovery prerequisites and ensure relevant resources are not listed in the Resource Inclusion List table to prevent duplicate discovery. * **Pattern Activation:** The Reserved Instance discovery pattern is disabled by default and must be enabled. Activation or deactivation is preserved through upgrades without being treated as a customization. * **GovCloud Support:** Discovery schedules can be configured to support AWS GovCloud by using appropriate datacenter URLs when setting up AWS service accounts. * **Data Collection:** The pattern gathers detailed Reserved Instance information and populates it into: * **Non-CMDB Tables:** Data such as Reserved Instance details is stored here, accessible under All \> Configuration \> AWS. * **CMDB Tables:** Virtual Machine Instances are updated with Reserved Instance information, including install and operational status. * **CI Relationships:** The pattern establishes relationships between Reserved Instances, Virtual Machine Instances, and AWS Datacenters to provide comprehensive discovery mapping. * **AWS Tag Discovery:** Tags associated with Reserved Instances are collected and stored in the Key Value table, enabling enhanced resource categorization. ## Key Outcomes * Accurate identification and tracking of AWS EC2 Reserved Instances within the ServiceNow CMDB and associated tables. * Improved visibility into the configuration, state, and relationships of Reserved Instances, facilitating better cloud resource management. * Support for AWS GovCloud environments and seamless pattern updates without losing configuration settings. * Enhanced asset and cost management capabilities through tag discovery and detailed resource metadata. Discovery and Service Mapping Patterns finds AWS services on your cloud environment. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store. ## Pattern-based discovery and mapping requirements {#aws-ec2-reserved-instance__selection_ipy_53n_jfc} Verify the AWS discovery prerequisites : For more information, see the prerequisites section in [AWS discovery using patterns](https://www.servicenow.com/docs/NFaTlkGaSxMWb2bQPsCnCA "Discovery and Service Mapping Patterns uses patterns to discover components of the Amazon AWS Cloud deployment during horizontal discovery. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store."). Remove resources from the Resource Inclusion List table : Verify that the relevant resource isn't listed in the Resource Inclusion List \[sa_cloud_inventory_resource_whitelist\] table to avoid duplicate discovery. For more information on removing resources from the Resource Inclusion List, see [AWS Resource Inventory discovery with Patterns](https://www.servicenow.com/docs/0pDNq0441mpy~sExfQvvqA "The ServiceNow Discovery and Service Mapping applications can find and map the AWS resources available by AWS Config Service. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store."). Enable the relevant pattern : The pattern for this service is disabled by default. Starting with Visibility Content version 6.28.0, activating or deactivating a pattern won't be considered a customization, and it will continue to receive updates. Patterns that were previously activated or deactivated will reset to the latest predefined version after upgrading while retaining the last active field value. For more information on enabling patterns, see [Activate a disabled pattern](https://www.servicenow.com/docs/aypCYVQdO8oFebLMLEI89g "If you want to use a pattern for discovery that's disabled by default, activate it manually.").{#aws-ec2-reserved-instance__activating-disabled-pattern-not-customization} Configure the Discovery schedule to support GovCloud : Discovering AWS GovCloud (US) accounts requires using a datacenter URL when setting up an AWS service account. For more information, see [Create AWS service accounts](https://www.servicenow.com/docs/vpueuFRHMWLNi6dzsJv94A "Create AWS service accounts on the ServiceNow AI Platform to access your AWS account during AWS discovery."). Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables. ## Data stored in non-CMDB tables {#aws-ec2-reserved-instance__section_aq4_qkq_hfc} Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Amazon AWS - Elastic Compute Cloud Reserved Instance - Extended Inventory (LP) pattern. You can review the non-CMDB AWS tables by navigating to AllConfigurationAWS. You can also search the navigation filter for the specific pattern name. {#aws-ec2-reserved-instance__section_aq4_qkq_hfc__entry__2} | Field | Description | |-|-| | Object Id \[object_id\] | The Amazon Resource Name (ARN) uniquely identifying the Reserved Instance. The ARN consists of the region, account ID, and instance ID in the following format: arn:aws:ec2:\:\:reserved-instances/\. | | Name \[name\] | The unique identifier assigned to the EC2 instance. | | State \[state\] | The current status or lifecycle state of the EC2 instance. | | Configuration Item \[configuration_item\] | References the Virtual Machine Instance \[cmdb_ci_vm_instance\] table. | | Instance Type \[instance_type\] | The type of EC2 instance. For example: t2.micro or m5.large. | | Scope \[scope\] | The reservation scope. For example: Regional or Availability Zone. | [Table 1. AWS Elastic Compute Cloud - Reserved Instance \[cmdb_aws_elastic_cloud_compute_reserved_instance\]] ## Data stored in CMDB tables Discovery and Service Mapping Patterns application populates data in the CMDB when running the Amazon AWS - Elastic Compute Cloud Reserved Instance - Extended Inventory (LP) pattern. {#aws-ec2-reserved-instance__entry__16} | Field | Description | |-|-| | Object ID \[object_id\] | The ARN uniquely identifying the Reserved Instance.
