SDK for PHP 3.x

Client: Aws\Synthetics\SyntheticsClient
Service ID: synthetics
Version: 2017-10-11

This page describes the parameters and results for the operations of the Synthetics (2017-10-11), and shows how to use the Aws\Synthetics\SyntheticsClient object to call the described operations. This documentation is specific to the 2017-10-11 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Operations

AssociateResource

$result = $client->associateResource([/* ... */]);
$promise = $client->associateResourceAsync([/* ... */]);

Associates a canary with a group. Using groups can help you with managing and automating your canaries, and you can also view aggregated run results and statistics for all canaries in a group.

You must run this operation in the Region where the canary exists.

Parameter Syntax

$result = $client->associateResource([
    'GroupIdentifier' => '<string>', // REQUIRED
    'ResourceArn' => '<string>', // REQUIRED
]);

Parameter Details

Members
GroupIdentifier
Required: Yes
Type: string

Specifies the group. You can specify the group name, the ARN, or the group ID as the GroupIdentifier.

ResourceArn
Required: Yes
Type: string

The ARN of the canary that you want to associate with the specified group.

Result Syntax

[]

Result Details

The results for this operation are always empty.

Errors

InternalServerException:

An unknown internal error occurred.

ValidationException:

A parameter could not be validated.

ResourceNotFoundException:

One of the specified resources was not found.

ConflictException:

A conflicting operation is already in progress.

ServiceQuotaExceededException:

The request exceeded a service quota value.

CreateCanary

$result = $client->createCanary([/* ... */]);
$promise = $client->createCanaryAsync([/* ... */]);

Creates a canary. Canaries are scripts that monitor your endpoints and APIs from the outside-in. Canaries help you check the availability and latency of your web services and troubleshoot anomalies by investigating load time data, screenshots of the UI, logs, and metrics. You can set up a canary to run continuously or just once.

Do not use CreateCanary to modify an existing canary. Use UpdateCanary instead.

To create canaries, you must have the CloudWatchSyntheticsFullAccess policy. If you are creating a new IAM role for the canary, you also need the iam:CreateRole, iam:CreatePolicy and iam:AttachRolePolicy permissions. For more information, see Necessary Roles and Permissions.

Do not include secrets or proprietary information in your canary names. The canary name makes up part of the Amazon Resource Name (ARN) for the canary, and the ARN is included in outbound calls over the internet. For more information, see Security Considerations for Synthetics Canaries.

Parameter Details

Members
ArtifactConfig
Type: ArtifactConfigInput structure

A structure that contains the configuration for canary artifacts, including the encryption-at-rest settings for artifacts that the canary uploads to Amazon S3.

ArtifactS3Location
Required: Yes
Type: string

The location in Amazon S3 where Synthetics stores artifacts from the test runs of this canary. Artifacts include the log file, screenshots, and HAR files. The name of the S3 bucket can't include a period (.).

Code
Required: Yes
Type: CanaryCodeInput structure

A structure that includes the entry point from which the canary should start running your script. If the script is stored in an S3 bucket, the bucket name, key, and version are also included.

ExecutionRoleArn
Required: Yes
Type: string

The ARN of the IAM role to be used to run the canary. This role must already exist, and must include lambda.amazonaws.com as a principal in the trust policy. The role must also have the following permissions:

  • s3:PutObject

  • s3:GetBucketLocation

  • s3:ListAllMyBuckets

  • cloudwatch:PutMetricData

  • logs:CreateLogGroup

  • logs:CreateLogStream

  • logs:PutLogEvents

FailureRetentionPeriodInDays
Type: int

The number of days to retain data about failed runs of this canary. If you omit this field, the default of 31 days is used. The valid range is 1 to 455 days.

Name
Required: Yes
Type: string

The name for this canary. Be sure to give it a descriptive name that distinguishes it from other canaries in your account.

Do not include secrets or proprietary information in your canary names. The canary name makes up part of the canary ARN, and the ARN is included in outbound calls over the internet. For more information, see Security Considerations for Synthetics Canaries.

ProvisionedResourceCleanup
Type: string

Specifies whether to also delete the Lambda functions and layers used by this canary when the canary is deleted. If you omit this parameter, the default of AUTOMATIC is used, which means that the Lambda functions and layers will be deleted when the canary is deleted.

If the value of this parameter is OFF, then the value of the DeleteLambda parameter of the DeleteCanary operation determines whether the Lambda functions and layers will be deleted.

ResourcesToReplicateTags
Type: Array of strings

To have the tags that you apply to this canary also be applied to the Lambda function that the canary uses, specify this parameter with the value lambda-function.

If you specify this parameter and don't specify any tags in the Tags parameter, the canary creation fails.

Specifies the runtime version to use for the canary. For a list of valid runtime versions and more information about runtime versions, see Canary Runtime Versions.

Schedule
Required: Yes
Type: CanaryScheduleInput structure

A structure that contains information about how often the canary is to run and when these test runs are to stop.

SuccessRetentionPeriodInDays
Type: int

The number of days to retain data about successful runs of this canary. If you omit this field, the default of 31 days is used. The valid range is 1 to 455 days.

Tags
Type: Associative array of custom strings keys (TagKey) to strings

A list of key-value pairs to associate with the canary. You can associate as many as 50 tags with a canary.

Tags can help you organize and categorize your resources. You can also use them to scope user permissions, by granting a user permission to access or change only the resources that have certain tag values.

To have the tags that you apply to this canary also be applied to the Lambda function that the canary uses, specify this parameter with the value lambda-function.

VpcConfig
Type: VpcConfigInput structure

If this canary is to test an endpoint in a VPC, this structure contains information about the subnet and security groups of the VPC endpoint. For more information, see Running a Canary in a VPC.

Canary
Type: Canary structure

The full details about the canary you have created.

Errors

InternalServerException:

An unknown internal error occurred.

ValidationException:

A parameter could not be validated.

RequestEntityTooLargeException:

One of the input resources is larger than is allowed.

CreateGroup

$result = $client->createGroup([/* ... */]);
$promise = $client->createGroupAsync([/* ... */]);

Creates a group which you can use to associate canaries with each other, including cross-Region canaries. Using groups can help you with managing and automating your canaries, and you can also view aggregated run results and statistics for all canaries in a group.

Groups are global resources. When you create a group, it is replicated across Amazon Web Services Regions, and you can view it and add canaries to it from any Region. Although the group ARN format reflects the Region name where it was created, a group is not constrained to any Region. This means that you can put canaries from multiple Regions into the same group, and then use that group to view and manage all of those canaries in a single view.

Groups are supported in all Regions except the Regions that are disabled by default. For more information about these Regions, see Enabling a Region.

Each group can contain as many as 10 canaries. You can have as many as 20 groups in your account. Any single canary can be a member of up to 10 groups.

Parameter Syntax

$result = $client->createGroup([
    'Name' => '<string>', // REQUIRED
    'Tags' => ['<string>', ...],
]);

Parameter Details

Members
Name
Required: Yes
Type: string

The name for the group. It can include any Unicode characters.

The names for all groups in your account, across all Regions, must be unique.

Tags
Type: Associative array of custom strings keys (TagKey) to strings

A list of key-value pairs to associate with the group. You can associate as many as 50 tags with a group.

Tags can help you organize and categorize your resources. You can also use them to scope user permissions, by granting a user permission to access or change only the resources that have certain tag values.

DeleteCanary

$result = $client->deleteCanary([/* ... */]);
$promise = $client->deleteCanaryAsync([/* ... */]);

Permanently deletes the specified canary.

If the canary's ProvisionedResourceCleanup field is set to AUTOMATIC or you specify DeleteLambda in this operation as true, CloudWatch Synthetics also deletes the Lambda functions and layers that are used by the canary.

Other resources used and created by the canary are not automatically deleted. After you delete a canary, you should also delete the following:

  • The CloudWatch alarms created for this canary. These alarms have a name of Synthetics-Alarm-first-198-characters-of-canary-name-canaryId-alarm number

  • Amazon S3 objects and buckets, such as the canary's artifact location.

  • IAM roles created for the canary. If they were created in the console, these roles have the name role/service-role/CloudWatchSyntheticsRole-First-21-Characters-of-CanaryName

  • CloudWatch Logs log groups created for the canary. These logs groups have the name /aws/lambda/cwsyn-First-21-Characters-of-CanaryName

Before you delete a canary, you might want to use GetCanary to display the information about this canary. Make note of the information returned by this operation so that you can delete these resources after you delete the canary.

Parameter Syntax

$result = $client->deleteCanary([
    'DeleteLambda' => true || false,
    'Name' => '<string>', // REQUIRED
]);

Parameter Details

Members
DeleteLambda
Type: boolean

Specifies whether to also delete the Lambda functions and layers used by this canary. The default is false.

Your setting for this parameter is used only if the canary doesn't have AUTOMATIC for its ProvisionedResourceCleanup field. If that field is set to AUTOMATIC, then the Lambda functions and layers will be deleted when this canary is deleted.

Type: Boolean

Name
Required: Yes
Type: string

The name of the canary that you want to delete. To find the names of your canaries, use DescribeCanaries.

Result Syntax

DeleteGroup

$result = $client->deleteGroup([/* ... */]);
$promise = $client->deleteGroupAsync([/* ... */]);

Deletes a group. The group doesn't need to be empty to be deleted. If there are canaries in the group, they are not deleted when you delete the group.

Groups are a global resource that appear in all Regions, but the request to delete a group must be made from its home Region. You can find the home Region of a group within its ARN.

Parameter Syntax

$result = $client->deleteGroup([
    'GroupIdentifier' => '<string>', // REQUIRED

DescribeCanaries

$result = $client->describeCanaries([/* ... */]);
$promise = $client->describeCanariesAsync([/* ... */]);

This operation returns a list of the canaries in your account, along with full details about each canary.

This operation supports resource-level authorization using an IAM policy and the Names parameter. If you specify the Names parameter, the operation is successful only if you have authorization to view all the canaries that you specify in your request. If you do not have permission to view any of the canaries, the request fails with a 403 response.

You are required to use the Names parameter if you are logged on to a user or role that has an IAM policy that restricts which canaries that you are allowed to view. For more information, see Limiting a user to viewing specific canaries.

Tags don't have any semantic meaning to Amazon Web Services and are interpreted strictly as strings of characters.

You can use the TagResource action with a resource that already has tags. If you specify a new tag key for the resource, this tag is appended to the list of tags associated with the resource. If you specify a tag key that is already associated with the resource, the new tag value that you specify replaces the previous value for that tag.

You can associate as many as 50 tags with a canary or group.
