Describes one or more of your managed nodes, including information about the operating system platform, the version of SSM Agent installed on the managed node, node status, and so on.
If you specify one or more managed node IDs, it returns information for those managed nodes. If you don’t specify node IDs, it returns information for all your managed nodes. If you specify a node ID that isn’t valid or a node that you don’t own, you receive an error.
Note
The IamRole
field for this API operation is the Identity and Access Management (IAM) role assigned to on-premises managed nodes. This call doesn’t return the IAM role for EC2 instances.
See also: AWS API Documentation
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
(list)
This is a legacy method. We recommend that you don’t use this method. Instead, use the
Filters
data type.Filters
enables you to return node information by filtering based on tags applied to managed nodes.Note
Attempting to use
InstanceInformationFilterList
andFilters
leads to an exception error.(structure)
Describes a filter for a specific list of managed nodes. You can filter node information by using tags. You specify tags by using a key-value mapping.
Use this operation instead of the DescribeInstanceInformationRequest$InstanceInformationFilterList method. The
InstanceInformationFilterList
method is a legacy method and doesn’t support tags.key -> (string)
The name of the filter.
valueSet -> (list)
The filter values.

--cli-input-json
|--cli-input-yaml
(string) Reads arguments from the JSON string provided. The JSON string follows the format provided by--generate-cli-skeleton
. If other arguments are provided on the command line, those 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. This may not be specified along with--cli-input-yaml
.
--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 theNextToken
value in thestarting-token
argument of a subsequent command. Do not use theNextToken
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 valueinput
, prints a sample input JSON that can be used as an argument for--cli-input-json
. Similarly, if providedyaml-input
it will print a sample input YAML that can be used with--cli-input-yaml
. If provided with the valueoutput
, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.Global Options¶
--debug
(boolean)Turn on debug logging.
--endpoint-url
(string)Override command’s default URL with the given URL.
--no-verify-ssl
(boolean)By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.
--no-paginate
(boolean)Disable automatic pagination.
--output
(string)The formatting style for command output.
json
text
table
yaml
yaml-stream
--query
(string)A JMESPath query to use in filtering the response data.
--profile
(string)Use a specific profile from your credential file.
--region
(string)The region to use. Overrides config/env settings.
--version
(string)Display the version of this tool.
--color
(string)Turn on/off color output.
on
off
auto
--no-sign-request
(boolean)Do not sign requests. Credentials will not be loaded if this argument is provided.
--ca-bundle
(string)The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.
--cli-read-timeout
(int)The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.
--cli-connect-timeout
(int)The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.
--cli-binary-format
(string)The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob
fileb://
will always be treated as binary and use the file contents directly regardless of thecli-binary-format
setting. When usingfile://
the file contents will need to properly formatted for the configuredcli-binary-format
.
base64
raw-in-base64-out
--no-cli-pager
(boolean)Disable cli pager for output.
--cli-auto-prompt
(boolean)Automatically prompt for CLI input parameters.
--no-cli-auto-prompt
(boolean)Disable automatically prompt for CLI input parameters.
Examples¶
Note
To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.
Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
