Main.Synthetics.associate_resourceMethod
associate_resource(resource_arn, group_identifier)
associate_resource(resource_arn, group_identifier, params::Dict{String,<:Any})

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.

Arguments

  • resource_arn: The ARN of the canary that you want to associate with the specified group.
  • group_identifier: Specifies the group. You can specify the group name, the ARN, or the group ID as the GroupIdentifier.

Main.Synthetics.create_canaryMethod
create_canary(artifact_s3_location, code, execution_role_arn, name, runtime_version, schedule)
create_canary(artifact_s3_location, code, execution_role_arn, name, runtime_version, schedule, params::Dict{String,<:Any})

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.

Arguments

  • artifact_s3_location: 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: 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.
  • execution_role_arn: 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
  • name: 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.
  • runtime_version: 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: A structure that contains information about how often the canary is to run and when these test runs are to stop.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

  • "ArtifactConfig": A structure that contains the configuration for canary artifacts, including the encryption-at-rest settings for artifacts that the canary uploads to Amazon S3.
  • "FailureRetentionPeriodInDays": 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.
  • "RunConfig": A structure that contains the configuration for individual canary runs, such as timeout value and environment variables. The environment variables keys and values are not encrypted. Do not store sensitive information in this field.
  • "SuccessRetentionPeriodInDays": 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": 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.
  • "VpcConfig": 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.

Main.Synthetics.create_groupMethod
create_group(name)
create_group(name, params::Dict{String,<:Any})

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.

Arguments

  • name: 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.

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

  • "Tags": 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.
source
Main.Synthetics.delete_canaryMethod
delete_canary(name)
delete_canary(name, params::Dict{String,<:Any})

Permanently deletes the specified canary. If you specify DeleteLambda to 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 that you do not intend to use again, you should also delete the following: The CloudWatch alarms created for this canary. These alarms have a name of Synthetics-SharpDrop-Alarm-MyCanaryName . 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-MyCanaryName . CloudWatch Logs log groups created for the canary. These logs groups have the name /aws/lambda/cwsyn-MyCanaryName . 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.

Arguments

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

Optional Parameters

Optional parameters can be passed as a params::Dict{String,<:Any}. Valid keys are:

  • "deleteLambda": Specifies whether to also delete the Lambda functions and layers used by this canary. The default is false. Type: Boolean
source
Main.Synthetics.delete_groupMethod
delete_group(group_identifier)
delete_group(group_identifier, params::Dict{String,<:Any})

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.

Arguments

  • group_identifier: Specifies which group to delete. You can specify the group name, the ARN, or the group ID as the GroupIdentifier.
