Adds or overwrites one or more tags for the specified resource. Tags are metadata that you assign to your managed instances. Tags enable you to categorize your managed instances in different ways, for example, by purpose, owner, or environment. Each tag consists of a key and an optional value, both of which you define. For example, you could define a set of tags for your account’s managed instances that helps you track each instance’s owner and stack level. For example: Key=Owner and Value=DbAdmin, SysAdmin, or Dev. Or Key=Stack and Value=Production, Pre-Production, or Test. Each resource can have a maximum of 10 tags.

We recommend that you devise a set of tag keys that meets your needs for each resource type. Using a consistent set of tag keys makes it easier for you to manage your resources. You can search and filter the resources based on the tags you add. Tags don’t have any semantic meaning to Amazon EC2 and are interpreted strictly as a string of characters.

For more information about tags, see Tagging Your Amazon EC2 Resources in the Amazon EC2 User Guide.

Attempts to cancel the command specified by the Command ID. There is no guarantee that the command will be terminated and the underlying process stopped.

Registers your on-premises server or virtual machine with Amazon EC2 so that you can manage these resources using Run Command. An on-premises server or virtual machine that has been registered with EC2 is called a managed instance. For more information about activations, see Setting Up Managed Instances (Linux) or Setting Up Managed Instances (Windows) in the Amazon EC2 User Guide.

Associates the specified SSM document with the specified instances or targets.

When you associate an SSM document with one or more instances using instance IDs or tags, the SSM agent running on the instance processes the document and configures the instance as specified.

If you associate a document with an instance that already has an associated document, the system throws the AssociationAlreadyExists exception.

Associates the specified SSM document with the specified instances or targets.

When you associate an SSM document with one or more instances using instance IDs or tags, the SSM agent running on the instance processes the document and configures the instance as specified.

If you associate a document with an instance that already has an associated document, the system throws the AssociationAlreadyExists exception.

Creates an SSM document.

After you create an SSM document, you can use CreateAssociation to associate it with one or more running instances.

Creates a new Maintenance Window.

Creates a patch baseline.

Deletes an activation. You are not required to delete an activation. If you delete an activation, you can no longer use it to register additional managed instances. Deleting an activation does not de-register managed instances. You must manually de-register managed instances.

Disassociates the specified SSM document from the specified instance.

When you disassociate an SSM document from an instance, it does not change the configuration of the instance. To change the configuration state of an instance after you disassociate a document, you must create a new document with the desired configuration and associate it with the instance.

Deletes the SSM document and all instance associations to the document.

Before you delete the SSM document, we recommend that you use DeleteAssociation to disassociate all instances that are associated with the document.

Deletes a Maintenance Window.

Delete a parameter from the system.

Deletes a patch baseline.

Removes the server or virtual machine from the list of registered servers. You can reregister the instance again at any time. If you don’t plan to use Run Command on the server, we suggest uninstalling the SSM agent first.

Removes a patch group from a patch baseline.

Removes a target from a Maintenance Window.

Removes a task from a Maintenance Window.

Details about the activation, including: the date and time the activation was created, the expiration date, the IAM role assigned to the instances in the activation, and the number of instances activated by this registration.

All associations for the instance(s).

Retrieves the current effective patches (the patch and the approval state) for the specified patch baseline.

The status of the associations for the instance(s).

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.

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

Retrieves the high-level patch state for the instances in the specified patch group.

Retrieves information about the patches on the specified instance and their state relative to the patch baseline being used for the instance.

For a given Maintenance Window execution, lists the tasks that were executed.

Retrieves the default patch baseline.

Retrieves the current snapshot for the patch baseline the instance uses. This API is primarily used by the AWS-ApplyPatchBaseline Systems Manager document.

Gets the contents of the specified SSM document.

Query inventory information.

Return a list of inventory type names for the account, or return a list of attribute names for a specific Inventory item type.

An invocation is copy of a command sent to a specific instance. A command can apply to one or more instances. A command invocation applies to one instance. For example, if a user executes SendCommand against three instances, then a command invocation is created for each requested instance ID. ListCommandInvocations provide status about command execution.

Lists the commands requested by users of the AWS account.

List all versions for a document.

Describes one or more of your SSM documents.

A list of inventory items returned by the request.
