Adds or overwrites one or more tags for the specified resource.

Tags are metadata that you can assign to your documents, managed instances, maintenance windows, Parameter Store parameters, and patch baselines. Tags enable you to categorize your resources 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,Value=DbAdmin

• Key=Owner,Value=SysAdmin

• Key=Owner,Value=Dev

• Key=Stack,Value=Production

• Key=Stack,Value=Pre-Production

• Key=Stack,Value=Test

Each resource can have a maximum of 50 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 and are interpreted strictly as a string of characters.

For more information about using tags with Amazon Elastic Compute Cloud (Amazon EC2) instances, see Tagging your Amazon EC2 resources in the Amazon EC2 User Guide.

Associates a related resource to a Systems Manager OpsCenter OpsItem.

For example, you can associate an Incident Manager incident or analysis with an OpsItem. Incident Manager is a capability of Amazon Web Services Systems Manager.

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.

Stops a maintenance window execution that is already in progress and cancels any tasks in the window that haven't already starting running.

Tasks already in progress will continue to completion.

Generates an activation code and activation ID you can use to register your on-premises server or virtual machine (VM) with Amazon Web Services Systems Manager.

Registering these machines with Systems Manager makes it possible to manage them using Systems Manager capabilities. You use the activation code and ID when installing SSM Agent on machines in your hybrid environment. For more information about requirements for managing on-premises instances and VMs using Systems Manager, see Setting up Amazon Web Services Systems Manager for hybrid environments in the Amazon Web Services Systems Manager User Guide.

On-premises servers or VMs that are registered with Systems Manager and Amazon Elastic Compute Cloud (Amazon EC2) instances that you manage with Systems Manager are all called managed instances.

A State Manager association defines the state that you want to maintain on your instances.

For example, an association can specify that anti-virus software must be installed and running on your instances, or that certain ports must be closed. For static targets, the association specifies a schedule for when the configuration is reapplied. For dynamic targets, such as an Amazon Web Services resource group or an Amazon Web Services autoscaling group, State Manager, a capability of Amazon Web Services Systems Manager applies the configuration when new instances are added to the group. The association also specifies actions to take when applying the configuration. For example, an association for anti-virus software might run once a day. If the software isn't installed, then State Manager installs it. If the software is installed, but the service isn't running, then the association might instruct State Manager to start the service.

Associates the specified Amazon Web Services Systems Manager document (SSM document) with the specified instances or targets.

When you associate a document with one or more instances using instance IDs or tags, Amazon Web Services Systems Manager Agent (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 returns the AssociationAlreadyExists exception.

Creates a Amazon Web Services Systems Manager (SSM document).

An SSM document defines the actions that Systems Manager performs on your managed instances. For more information about SSM documents, including information about supported schemas, features, and syntax, see Amazon Web Services Systems Manager Documents in the Amazon Web Services Systems Manager User Guide.

Creates a new maintenance window.

The value you specify for Duration determines the specific end time for the maintenance window based on the time it begins. No maintenance window tasks are permitted to start after the resulting endtime minus the number of hours you specify for Cutoff. For example, if the maintenance window starts at 3 PM, the duration is three hours, and the value you specify for Cutoff is one hour, no maintenance window tasks can start after 5 PM.

Creates a new OpsItem.

You must have permission in Identity and Access Management (IAM) to create a new OpsItem. For more information, see Getting started with OpsCenter in the Amazon Web Services Systems Manager User Guide.

Operations engineers and IT professionals use Amazon Web Services Systems Manager OpsCenter to view, investigate, and remediate operational issues impacting the performance and health of their Amazon Web Services resources. For more information, see Amazon Web Services Systems Manager OpsCenter in the Amazon Web Services Systems Manager User Guide.

If you create a new application in Application Manager, Amazon Web Services Systems Manager calls this API operation to specify information about the new application, including the application type.

Creates a patch baseline.

For information about valid key-value pairs in PatchFilters for each supported operating system type, see PatchFilter.

A resource data sync helps you view data from multiple sources in a single location.

Amazon Web Services Systems Manager offers two types of resource data sync: SyncToDestination and SyncFromSource.

You can configure Systems Manager Inventory to use the SyncToDestination type to synchronize Inventory data from multiple Regions to a single Amazon Simple Storage Service (Amazon S3) bucket. For more information, see Configuring resource data sync for Inventory in the Amazon Web Services Systems Manager User Guide.

You can configure Systems Manager Explorer to use the SyncFromSource type to synchronize operational work items (OpsItems) and operational data (OpsData) from multiple Regions to a single Amazon S3 bucket. This type can synchronize OpsItems and OpsData from multiple accounts and Regions or EntireOrganization by using Organizations. For more information, see Setting up Systems Manager Explorer to display data from multiple accounts and Regions in the Amazon Web Services Systems Manager User Guide.

A resource data sync is an asynchronous operation that returns immediately. After a successful initial sync is completed, the system continuously syncs data. To check the status of a sync, use the ListResourceDataSync.

By default, data isn't encrypted in Amazon S3. We strongly recommend that you enable encryption in Amazon S3 to ensure secure data storage. We also recommend that you secure access to the Amazon S3 bucket by creating a restrictive bucket policy.

Deletes an activation.

You aren't required to delete an activation. If you delete an activation, you can no longer use it to register additional managed instances. Deleting an activation doesn't de-register managed instances. You must manually de-register managed instances.

Disassociates the specified Amazon Web Services Systems Manager document (SSM document) from the specified instance.

When you disassociate a document from an instance, it doesn't 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 Amazon Web Services Systems Manager document (SSM document) and all instance associations to the document.

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

Get detailed information about a particular Automation execution.

Gets the state of a Amazon Web Services Systems Manager change calendar at the current time or a specified time.

If you specify a time, GetCalendarState returns the state of the calendar at that specific time, and returns the next time that the change calendar state will transition. If you don't specify a time, GetCalendarState uses the current time. Change Calendar entries have two possible states: OPEN or CLOSED.

If you specify more than one calendar in a request, the command returns the status of OPEN only if all calendars in the request are open. If one or more calendars in the request are closed, the status returned is CLOSED.

For more information about Change Calendar, a capability of Amazon Web Services Systems Manager, see Amazon Web Services Systems Manager Change Calendar in the Amazon Web Services Systems Manager User Guide.

Returns detailed information about command execution for an invocation or plugin.

GetCommandInvocation only gives the execution status of a plugin in a document. To get the command execution status on a specific instance, use ListCommandInvocations. To get the command execution status across instances, use ListCommands.

Retrieves the Session Manager connection status for an instance to determine whether it is running and ready to receive Session Manager connections.

Retrieves the default patch baseline.

Amazon Web Services Systems Manager supports creating multiple default patch baselines. For example, you can create a default patch baseline for each operating system.

If you don't specify an operating system value, the default patch baseline for Windows is returned.

Retrieves the current snapshot for the patch baseline the instance uses.

This API is primarily used by the AWS-RunPatchBaseline Systems Manager document (SSM document).

If you run the command locally, such as with the Command Line Interface (CLI), the system attempts to use your local AWS credentials and the operation fails. To avoid this, you can run the command in the Amazon Web Services Systems Manager console. Use Run Command, a capability of Amazon Web Services Systems Manager, with an SSM document that enables you to target an instance with a script or command. For example, run the command using the AWS-RunShellScript document or the AWS-RunPowerShellScript document.

Gets the contents of the specified Amazon Web Services Systems Manager document (SSM document).

Request results are returned on a best-effort basis. If you specify MaxResults in the request, the response includes information up to the limit specified. The number of items returned, however, can be between zero and the value of MaxResults. If the service reaches an internal limit while processing the results, it stops the operation and returns the matching values up to that point and a NextToken. You can specify the NextToken in a subsequent call to get the next set of results.

Retrieves information about a patch baseline.

Retrieves the patch baseline that should be used for the specified patch group.

ServiceSetting is an account-level setting for an Amazon Web Services service.

This setting defines how a user interacts with or uses a service or a feature of a service. For example, if an Amazon Web Services service charges money to the account based on feature or service usage, then the Amazon Web Services service team might create a default setting of false. This means the user can't use this feature unless they change the setting to true and intentionally opt in for a paid feature.

Services map a SettingId object to a setting value. Amazon Web Services services teams define the default value for a SettingId. You can't create a new SettingId, but you can overwrite the default value if you have the ssm:UpdateServiceSetting permission for the setting. Use the UpdateServiceSetting API operation to change the default setting. Or use the ResetServiceSetting to change the value back to the original value defined by the Amazon Web Services service team.

Query the current service setting for the account.

A parameter label is a user-defined alias to help you manage different versions of a parameter.

When you modify a parameter, Amazon Web Services Systems Manager automatically saves a new version and increments the version number by one. A label can help you remember the purpose of a parameter when there are multiple versions.

Parameter labels have the following requirements and restrictions.

• A version of a parameter can have a maximum of 10 labels.

• You can't attach the same label to different versions of the same parameter. For example, if version 1 has the label Production, then you can't attach Production to version 2.

• You can move a label from one version of a parameter to another.

• You can't create a label when you create a new parameter. You must attach a label to a specific version of a parameter.

• If you no longer want to use a parameter label, then you can either delete it or move it to a different version of a parameter.

• A label can have a maximum of 100 characters.

• Labels can contain letters (case sensitive), numbers, periods (.), hyphens (-), or underscores (_).

• Labels can't begin with a number, "aws" or "ssm" (not case sensitive). If a label fails to meet these requirements, then the label isn't associated with a parameter and the system displays it in the list of InvalidLabels.

Retrieves all versions of an association for a specific association ID.

Returns all State Manager associations in the current account and Region.

You can limit the results to a specific State Manager association document or instance by specifying a filter. State Manager is a capability of Amazon Web Services Systems Manager.

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 runs 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 account.

For a specified resource ID, this API operation returns a list of compliance statuses for different resource types.

Currently, you can only specify one resource ID per call. List results depend on the criteria specified in the filter.

Returns a summary count of compliant and non-compliant resources for a compliance type.

For example, this call can return State Manager associations, patches, or custom compliance types according to the filter criteria that you specify.

List all versions for a document.

Returns all Systems Manager (SSM) documents in the current account and Region.

You can limit the results of this request by using a filter.

A list of inventory items returned by the request.

Returns a list of all OpsItem events in the current Region and account.

You can limit the results to events associated with specific OpsItems by specifying a filter.

Lists all related-item resources associated with an OpsItem.

Amazon Web Services Systems Manager calls this API operation when displaying all Application Manager OpsMetadata objects or blobs.

Returns a resource-level summary count.

The summary includes information about compliant and non-compliant statuses and detailed compliance-item severity counts, according to the filter criteria you specify.

Lists your resource data sync configurations.

Includes information about the last time a sync attempted to start, the last sync status, and the last time a sync successfully completed.

The number of sync configurations might be too large to return using a single call to ListResourceDataSync. You can limit the number of sync configurations returned by using the MaxResults parameter. To determine whether there are more sync configurations to list, check the value of NextToken in the output. If there are more sync configurations to list, you can request them by specifying the NextToken returned in the call to the parameter of a subsequent call.

Returns a list of the tags assigned to the specified resource.

For information about the ID format for each supported resource type, see AddTagsToResource.

Shares a Amazon Web Services Systems Manager document (SSM document)publicly or privately.

If you share a document privately, you must specify the Amazon Web Services user account IDs for those people who can use the document. If you share a document publicly, you must specify All as the account ID.

Registers a compliance type and other compliance details on a designated resource.

This operation lets you register custom compliance details with a resource. This call overwrites existing compliance information on the resource, so you must provide a full list of compliance items each time that you send the request.

ComplianceType can be one of the following:

• ExecutionId: The execution ID when the patch, association, or custom compliance item was applied.

• ExecutionType: Specify patch, association, or Custom:string.

• ExecutionTime. The time the patch, association, or custom compliance item was applied to the instance.

• InstalledTime: The time the association, patch, or custom compliance item was applied to the resource. Specify the time by using the following format: yyyy-MM-dd'T'HH:mm:ss'Z'

Bulk update custom inventory items on one more instance.

The request adds an inventory item, if it doesn't already exist, or updates an inventory item, if it does exist.

Add a parameter to the system.

Defines the default patch baseline for the relevant operating system.

To reset the Amazon Web Services-predefined patch baseline as the default, specify the full patch baseline Amazon Resource Name (ARN) as the baseline ID value. For example, for CentOS, specify arn:aws:ssm:us-east-2:733109147000:patchbaseline/pb-0574b43a65ea646ed instead of pb-0574b43a65ea646ed.

Registers a patch baseline for a patch group.

Registers a target with a maintenance window.

Adds a new task to a maintenance window.

Removes tag keys from the specified resource.

ServiceSetting is an account-level setting for an Amazon Web Services service.

This setting defines how a user interacts with or uses a service or a feature of a service. For example, if an Amazon Web Services service charges money to the account based on feature or service usage, then the Amazon Web Services service team might create a default setting of "false". This means the user can't use this feature unless they change the setting to "true" and intentionally opt in for a paid feature.

Services map a SettingId object to a setting value. Amazon Web Services services teams define the default value for a SettingId. You can't create a new SettingId, but you can overwrite the default value if you have the ssm:UpdateServiceSetting permission for the setting. Use the GetServiceSetting API operation to view the current value. Use the UpdateServiceSetting API operation to change the default setting.

Reset the service setting for the account to the default value as provisioned by the Amazon Web Services service team.

Reconnects a session to an instance after it has been disconnected.

Connections can be resumed for disconnected sessions, but not terminated sessions.

This command is primarily for use by client machines to automatically reconnect during intermittent network issues. It isn't intended for any other use.

Sends a signal to an Automation execution to change the current behavior or status of the execution.

Runs commands on one or more managed instances.

Runs an association immediately and only one time.

Initiates a connection to a target (for example, an instance) for a Session Manager session.

Returns a URL and token that can be used to open a WebSocket connection for sending input and receiving outputs.

Amazon Web Services CLI usage: start-session is an interactive command that requires the Session Manager plugin to be installed on the client machine making the call. For information, see Install the Session Manager plugin for the Amazon Web Services CLI in the Amazon Web Services Systems Manager User Guide.

Amazon Web Services Tools for PowerShell usage: Start-SSMSession isn't currently supported by Amazon Web Services Tools for PowerShell on Windows local machines.

Stop an Automation that is currently running.

Permanently ends a session and closes the data connection between the Session Manager client and SSM Agent on the instance.

A terminated session isn't be resumed.

Remove a label or labels from a parameter.

Updates an association.

You can update the association name and version, the document version, schedule, parameters, and Amazon Simple Storage Service (Amazon S3) output.

In order to call this API operation, your Identity and Access Management (IAM) user account, group, or role must be configured with permission to call the DescribeAssociation API operation. If you don't have permission to call DescribeAssociation, then you receive the following error: An error occurred (AccessDeniedException) when calling the UpdateAssociation operation: User: <user_arn> isn't authorized to perform: ssm:DescribeAssociation on resource: <resource_arn>

When you update an association, the association immediately runs against the specified targets.

Updates the status of the Amazon Web Services Systems Manager document (SSM document) associated with the specified instance.

Updates one or more values for an SSM document.

Set the default version of a document.

Updates information related to approval reviews for a specific version of a document.

Updates an existing maintenance window.

Only specified parameters are modified.

The value you specify for Duration determines the specific end time for the maintenance window based on the time it begins. No maintenance window tasks are permitted to start after the resulting endtime minus the number of hours you specify for Cutoff. For example, if the maintenance window starts at 3 PM, the duration is three hours, and the value you specify for Cutoff is one hour, no maintenance window tasks can start after 5 PM.

Modifies the target of an existing maintenance window.

You can change the following:

• Name

• Description

• Owner

• IDs for an ID target

• Tags for a Tag target

• From any supported tag type to another. The three supported tag types are ID target, Tag target, and resource group. For more information, see Target.

If a parameter is null, then the corresponding field isn't modified.

Modifies a task assigned to a maintenance window.

You can't change the task type, but you can change the following values:

• TaskARN. For example, you can change a RUN_COMMAND task from AWS-RunPowerShellScript to AWS-RunShellScript.

• ServiceRoleArn

• TaskInvocationParameters

• Priority

• MaxConcurrency

• MaxErrors

One or more targets must be specified for maintenance window Run Command-type tasks. Depending on the task, targets are optional for other maintenance window task types (Automation, Lambda, and Step Functions). For more information about running tasks that don't specify targets, see Registering maintenance window tasks without targets in the Amazon Web Services Systems Manager User Guide.

If the value for a parameter in UpdateMaintenanceWindowTask is null, then the corresponding field isn't modified. If you set Replace to true, then all fields required by the RegisterTaskWithMaintenanceWindow operation are required for this request. Optional fields that aren't specified are set to null.

When you update a maintenance window task that has options specified in TaskInvocationParameters, you must provide again all the TaskInvocationParameters values that you want to retain. The values you don't specify again are removed. For example, suppose that when you registered a Run Command task, you specified TaskInvocationParameters values for Comment, NotificationConfig, and OutputS3BucketName. If you update the maintenance window task and specify only a different OutputS3BucketName value, the values for Comment and NotificationConfig are removed.

Changes the Identity and Access Management (IAM) role that is assigned to the on-premises instance or virtual machines (VM).

IAM roles are first assigned to these hybrid instances during the activation process. For more information, see CreateActivation.

Edit or change an OpsItem.

You must have permission in Identity and Access Management (IAM) to update an OpsItem. For more information, see Getting started with OpsCenter in the Amazon Web Services Systems Manager User Guide.

Operations engineers and IT professionals use Amazon Web Services Systems Manager OpsCenter to view, investigate, and remediate operational issues impacting the performance and health of their Amazon Web Services resources. For more information, see OpsCenter in the Amazon Web Services Systems Manager User Guide.

Amazon Web Services Systems Manager calls this API operation when you edit OpsMetadata in Application Manager.

Modifies an existing patch baseline.

Fields not specified in the request are left unchanged.

For information about valid key-value pairs in PatchFilters for each supported operating system type, see PatchFilter.

Update a resource data sync.

After you create a resource data sync for a Region, you can't change the account options for that sync. For example, if you create a sync in the us-east-2 (Ohio) Region and you choose the Include only the current account option, you can't edit that sync later and choose the Include all accounts from my Organizations configuration option. Instead, you must delete the first resource data sync, and create a new one.

This API operation only supports a resource data sync that was created with a SyncFromSource SyncType.

ServiceSetting is an account-level setting for an Amazon Web Services service.

This setting defines how a user interacts with or uses a service or a feature of a service. For example, if an Amazon Web Services service charges money to the account based on feature or service usage, then the Amazon Web Services service team might create a default setting of "false". This means the user can't use this feature unless they change the setting to "true" and intentionally opt in for a paid feature.

Services map a SettingId object to a setting value. Amazon Web Services services teams define the default value for a SettingId. You can't create a new SettingId, but you can overwrite the default value if you have the ssm:UpdateServiceSetting permission for the setting. Use the GetServiceSetting API operation to view the current value. Or, use the ResetServiceSetting to change the value back to the original value defined by the Amazon Web Services service team.

Update the service setting for the account.
