Command document plugin reference

This reference describes the plugins that you can specify in an AWS Systems Manager (SSM) Command type document. These plugins can't be used in SSM Automation runbooks, which use Automation actions. For information about AWS Systems Manager Automation actions, see Systems Manager Automation actions reference.

Systems Manager determines the actions to perform on a managed instance by reading the contents of an SSM document. Each document includes a code-execution section. Depending on the schema version of your document, this code-execution section can include one or more plugins or steps. For the purpose of this Help topic, plugins and steps are called plugins. This section includes information about each of the Systems Manager plugins. For more information about documents, including information about creating documents and the differences between schema versions, see AWS Systems Manager Documents.

For plugins that accept String parameters, such as aws:runShellScript and aws:runPowerShellScript, the interpolationType parameter can be used to enhance security by treating parameter inputs as string literals rather than potentially executable commands. For example:

{
    "schemaVersion": "2.2",
    "description": "runShellScript with command strings stored as Parameter Store parameter",
    "parameters": {
      "commands": {
        "type": "StringList",
        "description": "(Required) The commands to run on the instance.",
        "default": ["{{ ssm:myShellCommands }}"],
        "interpolationType" : "ENV_VAR"
      }
    },
    //truncated
 }
Note

Some of the plugins described here run only on either Windows Server instances or Linux instances. Platform dependencies are noted for each plugin.

The following document plugins are supported on Amazon Elastic Compute Cloud (Amazon EC2) instances for macOS:

  • aws:refreshAssociation

  • aws:runShellScript

  • aws:runPowerShellScript

  • aws:softwareInventory

  • aws:updateSsmAgent

Shared inputs

With SSM Agent version 3.0.502 and later only, all plugins can use the following inputs:

finallyStep

The last step you want the document to run. If this input is defined for a step, it takes precedence over an exit value specified in the onFailure or onSuccess inputs. In order for a step with this input to run as expected, the step must be the last one defined in the mainSteps of your document.

Type: Boolean

Valid values: true | false

Required: No

onFailure

If you specify this input for a plugin with the exit value and the step fails, the step status reflects the failure and the document doesn't run any remaining steps unless a finallyStep has been defined. If you specify this input for a plugin with the successAndExit value and the step fails, the step status shows successful and the document doesn't run any remaining steps unless a finallyStep has been defined.

Type: String

Valid values: exit | successAndExit

Required: No

onSuccess

If you specify this input for a plugin and the step runs successfully, the document doesn't run any remaining steps unless a finallyStep has been defined.

Type: String

Valid values: exit

Required: No

aws:cloudWatch

Export data from Windows Server to Amazon CloudWatch or Amazon CloudWatch Logs and monitor the data using CloudWatch metrics. This plugin only runs on Windows Server operating systems. For more information about configuring CloudWatch integration with Amazon Elastic Compute Cloud (Amazon EC2), see Collecting metrics, logs, and traces with the CloudWatch agent in the Amazon CloudWatch User Guide.

Important

The unified CloudWatch agent has replaced SSM Agent as the tool for sending log data to Amazon CloudWatch Logs. The SSM Agent aws:cloudWatch plugin is not supported. We recommend using only the unified CloudWatch agent for your log collection processes. For more information, see the following topics:

You can export and monitor the following data types:

ApplicationEventLog

Sends application event log data to CloudWatch Logs.

CustomLogs

Sends any text-based log file to Amazon CloudWatch Logs. The CloudWatch plugin creates a fingerprint for log files. The system then associates a data offset with each fingerprint. The plugin uploads files when there are changes, records the offset, and associates the offset with a fingerprint. This method is used to avoid a situation where a user turns on the plugin, associates the service with a directory that contains a large number of files, and the system uploads all of the files.

Warning

Be aware that if your application truncates or attempts to clean logs during polling, any logs specified for LogDirectoryPath can lose entries. If, for example, you want to limit log file size, create a new log file when that limit is reached, and then continue writing data to the new file.

ETW

Sends Event Tracing for Windows (ETW) data to CloudWatch Logs.

IIS

Sends IIS log data to CloudWatch Logs.

PerformanceCounter

Sends Windows performance counters to CloudWatch. You can select different categories to upload to CloudWatch as metrics. For each performance counter that you want to upload, create a PerformanceCounter section with a unique ID (for example, "PerformanceCounter2", "PerformanceCounter3", and so on) and configure its properties.

Note

If the AWS Systems Manager SSM Agent or the CloudWatch plugin is stopped, performance counter data isn't logged in CloudWatch. This behavior is different than custom logs or Windows Event logs. Custom logs and Windows Event logs preserve performance counter data and upload it to CloudWatch after SSM Agent or the CloudWatch plugin is available.

SecurityEventLog

Sends security event log data to CloudWatch Logs.

SystemEventLog

Sends system event log data to CloudWatch Logs.

You can define the following destinations for the data:

CloudWatch

The destination where your performance counter metric data is sent. You can add more sections with unique IDs (for example, "CloudWatch2", CloudWatch3", and so on), and specify a different Region for each new ID to send the same data to different locations.

CloudWatchLogs

The destination where your log data is sent. You can add more sections with unique IDs (for example, "CloudWatchLogs2", CloudWatchLogs3", and so on), and specify a different Region for each new ID to send the same data to different locations.

Required: No

DimensionName

A dimension for your Amazon CloudWatch metric. If you specify DimensionName, you must specify DimensionValue. These parameters provide another view when listing metrics. You can use the same dimension for multiple metrics so that you can view all metrics belonging to a specific dimension.

Type: String

Required: No

DimensionValue

A dimension value for your Amazon CloudWatch metric.

Type: String

Required: No

Flows

Each data type to upload, along with the destination for the data (CloudWatch or CloudWatch Logs). For example, to send a performance counter defined under "Id": "PerformanceCounter" to the CloudWatch destination defined under "Id": "CloudWatch", enter "PerformanceCounter,CloudWatch". Similarly, to send the custom log, ETW log, and system log to the CloudWatch Logs destination defined under "Id": "ETW", enter "(ETW),CloudWatchLogs". In addition, you can send the same performance counter or log file to more than one destination. For example, to send the application log to two different destinations that you defined under "Id": "CloudWatchLogs" and "Id": "CloudWatchLogs2", enter "ApplicationEventLog,(CloudWatchLogs, CloudWatchLogs2)".

The full name of the component.

Type: String

Required: Yes

Id

Identifies the data source or destination. This identifier must be unique within the configuration file.

Type: String

Required: Yes

InstanceName

The name of the performance counter instance. Don't use an asterisk (*) to indicate all instances because each performance counter component only supports one metric. You can, however use _Total.

Type: String

Required: Yes

Levels

The types of messages to send to Amazon CloudWatch.

Type: String

Valid values:

  • 1 - Only error messages uploaded.

  • 2 - Only warning messages uploaded.

  • 4 - Only information messages uploaded.

You can add values together to include more than one type of message. For example, 3 means that error messages (1) and warning messages (2) are included. A value of 7 means that error messages (1), warning messages (2), and informational messages (4) are included.

Required: Yes

Note

Windows Security Logs should set Levels to 7.

LineCount

The number of lines in the header to identify the log file. For example, IIS log files have virtually identical headers. You could enter 3, which would read the first three lines of the log file's header to identify it. In IIS log files, the third line is the date and time stamp, which is different between log files.

Type: Integer

Required: No

LogDirectoryPath

For CustomLogs, the path where logs are stored on your EC2 instance. For IIS logs, the folder where IIS logs are stored for an individual site (for example, C:\\inetpub\\logs\\LogFiles\\W3SVCn). For IIS logs, only W3C log format is supported. IIS, NCSA, and Custom formats aren't supported.

Type: String

Required: Yes

LogGroup

The name for your log group. This name is displayed on the Log Groups screen in the CloudWatch console.

Type: String

Required: Yes

LogName

The name of the log file.

  1. To find the name of the log, in Event Viewer, in the navigation pane, select Applications and Services Logs.

  2. In the list of logs, right-click the log you want to upload (for example, Microsoft > Windows > Backup > Operational), and then select Create Custom View.

  3. In the Create Custom View dialog box, select the XML tab. The LogName is in the <Select Path=> tag (for example, Microsoft-Windows-Backup). Copy this text into the LogName parameter.

Type: String

Valid values: Application | Security | System | Microsoft-Windows-WinINet/Analytic

Required: Yes

LogStream

The destination log stream. If you use {instance_id}, the default, the instance ID of this instance is used as the log stream name.

Type: String

Valid values: {instance_id} | {hostname} | {ip_address} <log_stream_name>

If you enter a log stream name that doesn't already exist, CloudWatch Logs automatically creates it for you. You can use a literal string or predefined variables ({instance_id}, {hostname}, {ip_address}, or a combination of all three to define a log stream name.

The log stream name specified in this parameter is displayed on the Log Groups > Streams for <YourLogStream> screen in the CloudWatch console.

Required: Yes

MetricName

The CloudWatch metric that you want performance data to be included under.

Note

Don't use special characters in the name. If you do, the metric and associated alarms might not work.

Type: String

Required: Yes

NameSpace

The metric namespace where you want performance counter data to be written.

Type: String

Required: Yes

PollInterval

How many seconds must elapse before new performance counter and log data is uploaded.

The timestamp format you want to use. For a list of supported values, see Custom Date and Time Format Strings in the MSDN Library.

Type: String

Required: Yes

TimeZoneKind

Provides time zone information when no time zone information is included in your log’s timestamp. If this parameter is left blank and if your timestamp doesn’t include time zone information, CloudWatch Logs defaults to the local time zone. This parameter is ignored if your timestamp already contains time zone information.

Type: String

Valid values: Local | UTC

Type: String

Required: Yes

Example: "directoryId": "d-1234567890"

directoryName

The name of the domain.

Type: String

Required: Yes

Example: "directoryName": "example.com"

directoryOU

The organizational unit (OU).

The IP addresses of the DNS servers.

Type: StringList

Required: Yes

Example: "dnsIpAddresses": ["198.51.100.1","198.51.100.2"]

hostname

The hostname you want to assign to the node. If not provided, there is no name change for Windows Server instances, while Linux instances will use the default naming pattern. If provided, Windows Server instances will use the exact provided value, while for Linux instances it serves as a prefix (unless keepHostName is set to "true").

Type: String

Required: No

keepHostName

Determines whether the hostname is changed for Linux instances when joined to the domain. This is a Linux-only parameter. By default (without inputs to hostname, hostnameNumAppendDigits, and with keepHostName as "false"), Linux hosts will be renamed to the pattern EC2AMAZ-XXXXXX. When set to "true", it keeps the original hostname and ignores inputs to hostname and hostnameNumAppendDigits.

Type: Boolean

Required: No

hostnameNumAppendDigits

Defines the number of random numeric digits to append after the hostname value. This is a Linux-only parameter and is used together with the hostname parameter. It is ignored if hostname is not provided.

Type: String

Allowed values: 1 to 5

Required: No

Examples

For examples, see Join an Amazon EC2 Instance to your AWS Managed Microsoft AD in the AWS Directory Service Administration Guide.

        "sourceInfo":"{{ sourceInfo }}"
      }
    }
  ]
}

Inputs

sourceType

The download source. Systems Manager supports the following source types for downloading scripts and SSM documents: GitHub, Git, HTTP, S3, and SSMDocument.

Type: String

Required: Yes

sourceInfo

The information required to retrieve the content from the required source.

Type: StringMap

Required: Yes

For sourceType GitHub, specify the following:

  • owner: The repository owner.

  • repository: The name of the repository.

  • path: The path to the file or directory you want to download.

  • getOptions: Extra options to retrieve content from a branch other than master or from a specific commit in the repository. getOptions can be omitted if you're using the latest commit in the master branch. If your repository was created after October 1, 2020 the default branch might be named main instead of master. In this case, you will need to specify values for the getOptions parameter.

    This parameter uses the following format:

    • branch:refs/heads/branch_name

      The default is master.

      To specify a non-default branch use the following format:

      branch:refs/heads/branch_name

    • commitID:commitID

      The default is head.

      To use the version of your SSM document in a commit other than the latest, specify the full commit ID. For example:

      "getOptions": "commitID:bbc1ddb94...b76d3bEXAMPLE",

  • tokenInfo: The Systems Manager parameter (a SecureString parameter) where you store your GitHub access token information, in the format {{ssm-secure:secure-string-token-name}}.

    Note

    This tokenInfo field is the only SSM document plugin field that supports a SecureString parameter. SecureString parameters aren't supported for any other fields, nor for any other SSM document plugins.

{
    "owner":"TestUser",
    "repository":"GitHubTest",
    "path":"scripts/python/test-script",
    "getOptions":"branch:master",
    "tokenInfo":"{{ssm-secure:secure-string-token}}"
}

For sourceType Git, you must specify the following:

  • repository

    The Git repository URL to the file or directory you want to download.

    Type: String

Additionally, you can specify the following optional parameters:

  • getOptions

    Extra options to retrieve content from a branch other than master or from a specific commit in the repository. getOptions can be omitted if you're using the latest commit in the master branch.

    Type: String

    This parameter uses the following format:

    • branch:refs/heads/branch_name

      The default is master.

      "branch" is required only if your SSM document is stored in a branch other than master. For example:

      "getOptions": "branch:refs/heads/main"

    • commitID:commitID

      The default is head.

      To use the version of your SSM document in a commit other than the latest, specify the full commit ID. For example:

      "getOptions": "commitID:bbc1ddb94...b76d3bEXAMPLE",

  • privateSSHKey

    The SSH key to use when connecting to the repository you specify. You can use the following format to reference a SecureString parameter for the value of your SSH key: {{ssm-secure:your-secure-string-parameter}}.

    Type: String

  • skipHostKeyChecking

    Determines the value of the StrictHostKeyChecking option when connecting to the repository you specify. The default value is false.

    Type: Boolean

  • username

    The username to use when connecting to the repository you specify using HTTP. You can use the following format to reference a SecureString parameter for the value of your username: {{ssm-secure:your-secure-string-parameter}}.

    Type: String

  • password

    The password to use when connecting to the repository you specify using HTTP. You can use the following format to reference a SecureString parameter for the value of your password: {{ssm-secure:your-secure-string-parameter}}.

    Type: String

For sourceType HTTP, you must specify the following:

  • url

    The URL to the file or directory you want to download.

    Type: String

Additionally, you can specify the following optional parameters:

  • allowInsecureDownload

    Determines whether a download can be performed over a connection that isn't encrypted with Secure Socket Layer (SSL) or Transport Layer Security (TLS). The default value is false. We don't recommend performing downloads without encryption. If you choose to do so, you assume all associated risks. Security is a shared responsibility between AWS and you. This is described as the shared responsibility model. To learn more, see the shared responsibility model.

    Type: Boolean

  • authMethod

    Determines whether a username and password are used for authentication when connecting to the url you specify. If you specify Basic or Digest, you must provide values for the username and password parameters. To use the Digest method, SSM Agent version 3.0.1181.0 or later must be installed on your instance. The Digest method supports MD5 and SHA256 encryption.

    Type: String

    Valid values: None | Basic | Digest

  • username

    The username to use when connecting to the url you specify using Basic authentication. You can use the following format to reference a SecureString parameter for the value of your username: {{ssm-secure:your-secure-string-parameter}}.

    Type: String

  • password

    The password to use when connecting to the url you specify using Basic authentication. You can use the following format to reference a SecureString parameter for the value of your password: {{ssm-secure:your-secure-string-parameter}}.

}

For sourceType SSMDocument, specify one of the following:

  • name: The name and version of the document in the following format: name:version. Version is optional. 

    {
    "name": "Example-RunPowerShellScript:3" 
}

  • name: The ARN for the document in the following format: arn:aws:ssm:region:account_id:document/document_name

    {
   "name":"arn:aws:ssm:us-east-2:3344556677:document/MySharedDoc"
}
destinationPath

An optional local path on the instance where you want to download the file. If you don't specify a path, the content is downloaded to a path relative to your command ID.

aws:softwareInventory

(Schema version 2.0 or later) Gather metadata about applications, files, and configurations on your managed instances. This plugin runs on Linux and Microsoft Windows Server operating systems. When you configure inventory collection, you start by creating an AWS Systems Manager State Manager association. Systems Manager collects the inventory data when the association is run. If you don't create the association first, and attempt to invoke the aws:softwareInventory plugin the system returns the following error:

The aws:softwareInventory plugin can only be invoked via ssm-associate.

An instance can have only one inventory association configured at a time. If you configure an instance with two or more associations, the inventory association doesn't run and no inventory data is collected. For more information about collecting inventory, see AWS Systems Manager Inventory.
