[ aws . ssm ]



Describes one or more of your instances. You can use this to get information about instances like the operating system platform, the SSM Agent version (Linux), status etc. If you specify one or more instance IDs, it returns information for those instances. If you do not specify instance IDs, it returns information for all your instances. If you specify an instance ID that is not valid or an instance that you do not own, you receive an error.


The IamRole field for this API action is the Amazon Identity and Access Management (IAM) role assigned to on-premises instances. This call does not return the IAM role for Amazon EC2 instances.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

describe-instance-information is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: InstanceInformationList


[--instance-information-filter-list <value>]
[--filters <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]


--instance-information-filter-list (list)

This is a legacy method. We recommend that you don't use this method. Instead, use the InstanceInformationFilter action. The InstanceInformationFilter action enables you to return instance information by using tags that are specified as a key-value mapping.

If you do use this method, then you can't use the InstanceInformationFilter action. Using this method and the InstanceInformationFilter action causes an exception error.

Shorthand Syntax:

key=string,valueSet=string,string ...

JSON Syntax:

    "key": "InstanceIds"|"AgentVersion"|"PingStatus"|"PlatformTypes"|"ActivationIds"|"IamRole"|"ResourceType"|"AssociationStatus",
    "valueSet": ["string", ...]

--filters (list)

One or more filters. Use a filter to return a more specific list of instances. You can filter on Amazon EC2 tag. Specify tags by using a key-value mapping.

Shorthand Syntax:

Key=string,Values=string,string ...

JSON Syntax:

    "Key": "string",
    "Values": ["string", ...]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


To describe managed instance information

This example shows details of each of your managed instances.


aws ssm describe-instance-information


  "InstanceInformationList": [
          "InstanceId": "i-1234567890abcdef0",
          "PingStatus": "Online",
          "LastPingDateTime": 1550501835.178,
          "AgentVersion": "2.3.415.0",
          "IsLatestVersion": false,
          "PlatformType": "Linux",
          "PlatformName": "Amazon Linux AMI",
          "PlatformVersion": "2018.03",
          "ResourceType": "EC2Instance",
          "IPAddress": "",
          "ComputerName": "ip-172-16-0-154.ec2.internal",
          "AssociationStatus": "Success",
          "LastAssociationExecutionDate": 1550501837.0,
          "LastSuccessfulAssociationExecutionDate": 1550501837.0,
          "AssociationOverview": {
              "InstanceAssociationStatusAggregatedCount": {
                  "Success": 1

To describe information about a specific managed instance

This example shows details of the managed instance i-1234567890abcdef0.


aws ssm describe-instance-information --filters "Key=InstanceIds,Values=i-1234567890abcdef0"

To describe information about managed instances with a specific tag key

This example shows details for managed instances that have the tag key DEV.


aws ssm describe-instance-information --filters "Key=tag-key,Values=DEV"
