It supports populating relevant configuration and inventory data into both CMDB and non-CMDB tables, helping maintain accurate cloud resource records. Show full answer Show less ## Key features * **Pattern Activation:** The EC2 Reserved Instance discovery pattern is disabled by default and requires activation. With Visibility Content version 6.28.0 and later, enabling or disabling patterns no longer counts as customization and patterns receive continuous updates. * **AWS Prerequisites:** Customers must meet AWS discovery prerequisites and ensure the resource is not listed in the Resource Inclusion List to prevent duplicate discovery. * **GovCloud Support:** Discovery for AWS GovCloud (US) accounts requires configuring the AWS service account with the appropriate datacenter URL. * **Data Population:** The pattern populates data into: * **Non-CMDB tables:** Stores detailed Reserved Instance inventory data. * **CMDB tables:** Updates Virtual Machine Instance CIs with instance details and statuses. * **Tag Discovery:** Collects AWS tags and stores them as key-value pairs in the cmdbkeyvalue table. * **CI Relationships:** Automatically creates relationships linking Reserved Instances to their corresponding Virtual Machine Instances and AWS Datacenters, enabling comprehensive service mapping. ## Practical benefits for ServiceNow customers * Enables detailed discovery and tracking of AWS EC2 Reserved Instances for improved cloud resource management. * Supports accurate CMDB population with up-to-date instance configurations, operational status, and tags, facilitating better visibility and governance. * Ensures seamless pattern updates without losing activation status, simplifying maintenance. * Facilitates discovery across standard AWS and GovCloud environments through proper service account configuration. * Prevents duplicate data by requiring removal of resources from the Resource Inclusion List before discovery. Discovery and Service Mapping Patterns finds AWS services on your cloud environment. Discovering some of these resources may 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 [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."). 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 [Amazon Web Services (AWS) Resource Inventory](https://servicenow-prod.fluidtopics.net/U2bwxjeyIbyEXySOOJQkYA "The ServiceNow Discovery and Service Mapping applications can find and map the AWS resources available by AWS Config Service. Discovering some of these resources may 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://servicenow-prod.fluidtopics.net/R5W5GP640V_5uNIhVNRPCw "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://servicenow-prod.fluidtopics.net/CvTA68TY3ph_FRR49RbdPg "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.

Default value is Installed. | | Operational status \[operational_status\] | Operational status of the resource. Default value is Operational. | | Description \[short_description\] | Type of resource. The value is set to AWS::Elastic Compute Cloud::Reserved Instance. | [Table 2. Virtual Machine Instance \[cmdb_ci_vm_instance\]] ## CI relationships The Amazon AWS - Elastic Compute Cloud Reserved Instance - Extended Inventory (LP) pattern creates these relationships to support Amazon EC2 Reserved Instance discovery. {#aws-ec2-reserved-instance__entry__29} | CI | Relationship | CI | |-|-|-| | Virtual Machine Instance \[cmdb_ci_vm_instance\] | Hosted on::Hosts | AWS Datacenter \[cmdb_ci_aws_datacenter\] | | AWS Elastic Compute Cloud - Reserved Instance \[cmdb_aws_elastic_cloud_compute_reserved_instance\] | References | Virtual Machine Instance \[cmdb_ci_vm_instance\] | [ ] ## AWS tag discovery {#aws-ec2-reserved-instance__section_ezc_jwt_jfc} The pattern collects tags and populates them in the Key Value \[cmdb_key_value\] table. {#aws-ec2-reserved-instance__table_axq_spc_y2c__entry__2} | Field | Description | |-|-| | Key \[key\] | Tag name. | | Value \[value\] | Tag value. | [Table 3.
