[ aws . ssm ]



Retrieves the high-level patch state of one or more instances.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--instance-ids <value>
[--next-token <value>]
[--max-results <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--instance-ids (list)

The ID of the instance whose patch state information should be retrieved.


"string" "string" ...

--next-token (string)

The token for the next set of items to return. (You received this token from a previous call.)

--max-results (integer)

The maximum number of instances to return (per page).

--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.

--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 get the patch summary states for instances

This example gets the patch summary states for an instance.


aws ssm describe-instance-patch-states --instance-ids "i-08ee91c0b17045407" "i-09a618aec652973a9"


  "InstancePatchStates": [


InstancePatchStates -> (list)

The high-level patch state for the requested instances.


Defines the high-level patch compliance state for a managed instance, providing information about the number of installed, missing, not applicable, and failed patches along with metadata about the operation when this information was gathered for the instance.

InstanceId -> (string)

The ID of the managed instance the high-level patch compliance information was collected for.

PatchGroup -> (string)

The name of the patch group the managed instance belongs to.

BaselineId -> (string)

The ID of the patch baseline used to patch the instance.

SnapshotId -> (string)

The ID of the patch baseline snapshot used during the patching operation when this compliance data was collected.

InstallOverrideList -> (string)

An https URL or an Amazon S3 path-style URL to a list of patches to be installed. This patch installation list, which you maintain in an Amazon S3 bucket in YAML format and specify in the SSM document AWS-RunPatchBaseline , overrides the patches specified by the default patch baseline.

For more information about the InstallOverrideList parameter, see About the SSM Document AWS-RunPatchBaseline in the AWS Systems Manager User Guide .

OwnerInformation -> (string)

Placeholder information. This field will always be empty in the current release of the service.

InstalledCount -> (integer)

The number of patches from the patch baseline that are installed on the instance.

InstalledOtherCount -> (integer)

The number of patches not specified in the patch baseline that are installed on the instance.

InstalledRejectedCount -> (integer)

The number of instances with patches installed that are specified in a RejectedPatches list. Patches with a status of InstalledRejected were typically installed before they were added to a RejectedPatches list.


If ALLOW_AS_DEPENDENCY is the specified option for RejectedPatchesAction, the value of InstalledRejectedCount will always be 0 (zero).

MissingCount -> (integer)

The number of patches from the patch baseline that are applicable for the instance but aren't currently installed.

FailedCount -> (integer)

The number of patches from the patch baseline that were attempted to be installed during the last patching operation, but failed to install.

NotApplicableCount -> (integer)

The number of patches from the patch baseline that aren't applicable for the instance and hence aren't installed on the instance.

OperationStartTime -> (timestamp)

The time the most recent patching operation was started on the instance.

OperationEndTime -> (timestamp)

The time the most recent patching operation completed on the instance.

Operation -> (string)

The type of patching operation that was performed: SCAN (assess patch compliance state) or INSTALL (install missing patches).

NextToken -> (string)

The token to use when requesting the next set of items. If there are no additional items to return, the string is empty.
