| activation_id | core | string | The activation ID created by Amazon Web Services Systems Manager when the server or virtual machine (VM) was registered. |
| agent_version | core | string | The version of SSM Agent running on your Linux managed node. |
| association_overview | core | json | Information about the association. |
| association_status | core | string | The status of the association. |
| compliance_items | core | json | A list of compliance information for the specified resource ID. |
| computer_name | core | string | The fully qualified host name of the managed node. |
| iam_role | core | string | The role assigned to an Amazon EC2 instance configured with a Systems Manager Quick Setup host management configuration or the role assigned to an on-premises managed node. This call doesn't return the IAM role for unmanaged Amazon EC2 instances (instances not configured for Systems Manager). To retrieve the role for an unmanaged instance, use the Amazon EC2 DescribeInstances operation. For information, see DescribeInstances in the Amazon EC2 API Reference or describe-instances in the Amazon Web Services CLI Command Reference. |
| instance_arn | core | string | |
| instance_id | core | string | The managed node ID. |
| ip_address | core | string | The IP address of the managed node. |
| is_latest_version | core | bool | Indicates whether the latest version of SSM Agent is running on your Linux managed node. This field doesn't indicate whether or not the latest version is installed on Windows managed nodes, because some older versions of Windows Server use the EC2Config service to process Systems Manager requests. |
| last_association_execution_date | core | timestamp | The date the association was last run. |
| last_ping_date_time | core | timestamp | The date and time when the agent last pinged the Systems Manager service. |
| last_successful_association_execution_date | core | timestamp | The last date the association was successfully run. |
| name | core | string | The name assigned to an on-premises server, edge device, or virtual machine (VM) when it is activated as a Systems Manager managed node. The name is specified as the DefaultInstanceName property using the CreateActivation command. It is applied to the managed node by specifying the Activation Code and Activation ID when you install SSM Agent on the node, as explained in How to install SSM Agent on hybrid Linux nodes and How to install SSM Agent on hybrid Windows Server nodes. To retrieve the Name tag of an EC2 instance, use the Amazon EC2 DescribeInstances operation. For information, see DescribeInstances in the Amazon EC2 API Reference or describe-instances in the Amazon Web Services CLI Command Reference. |
| ping_status | core | string | Connection status of SSM Agent. The status Inactive has been deprecated and is no longer in use. |
| platform_name | core | string | The name of the operating system platform running on your managed node. |
