describe-instance-information¶

Description¶

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.

Synopsis¶

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

Options¶

--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 and Filters 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.

(string)

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 managed nodes. You can filter based on tags applied to EC2 instances. Use this Filters data type instead of InstanceInformationFilterList , which is deprecated.

(structure)

The filters to describe or get information about your managed nodes.

Key -> (string)

The filter key name to describe your managed nodes. For example:

“InstanceIds”|”AgentVersion”|”PingStatus”|”PlatformTypes”|”ActivationIds”|”IamRole”|”ResourceType”|”AssociationStatus”|”Tag Key”

Warning

Tag key isn’t a valid filter. You must specify either tag-key or tag:keyname and a string. Here are some valid examples: tag-key, tag:123, tag:al!, tag:Windows. Here are some invalid examples: tag-keys, Tag Key, tag:, tagKey, abc:keyname.

Values -> (list)

The filter values.

(string)

Shorthand Syntax:

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

JSON Syntax:

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

--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 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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, 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.

See ‘aws help’ for descriptions of global 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 .

Example 1: To describe managed instance information

The following describe-instance-information example retrieves details of each of your managed instances.

aws ssm describe-instance-information

Example 2: To describe information about a specific managed instance

The following describe-instance-information example shows details of the managed instance i-028ea792daEXAMPLE.

aws ssm describe-instance-information \
    --filters "Key=InstanceIds,Values=i-028ea792daEXAMPLE"

Example 3: To describe information about managed instances with a specific tag key

The following describe-instance-information example shows details for managed instances that have the tag key DEV.

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

Output:

{
    "InstanceInformationList": [
        {
            "InstanceId": "i-028ea792daEXAMPLE",
            "PingStatus": "Online",
