create-canary

Description

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 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 .

Options

--name (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 .

--code (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.

S3Bucket -> (string)

If your canary script is located in S3, specify the full bucket name here. The bucket must already exist. Specify the full bucket name, including s3:// as the start of the bucket name.

S3Key -> (string)

The S3 key of your script. For more information, see Working with Amazon S3 Objects .

S3Version -> (string)

The S3 version ID of your script.

ZipFile -> (blob)

If you input your canary script directly into the canary instead of referring to an S3 location, the value of this parameter is the .zip file that contains the script. It can be up to 5 MB.

Handler -> (string)

The entry point to use for the source code when running the canary. This value must end with the string .handler .

Shorthand Syntax:

S3Bucket=string,S3Key=string,S3Version=string,ZipFile=blob,Handler=string

JSON Syntax:

{
  "S3Bucket": "string",
  "S3Key": "string",
  "S3Version": "string",
  "ZipFile": blob,
  "Handler": "string"
}

--artifact-s3-location (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.

--execution-role-arn (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:CreateLogStream

--schedule (structure)

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

Expression -> (string)

A rate expression that defines how often the canary is to run. The syntax is rate(*number unit* ) . unit can be minute , minutes , or hour .

For example, rate(1 minute) runs the canary once a minute, rate(10 minutes) runs it once every 10 minutes, and rate(1 hour) runs it once every hour. You can specify a frequency between rate(1 minute) and rate(1 hour) .

Specifying rate(0 minute) or rate(0 hour) is a special value that causes the canary to run only once when it is started.

DurationInSeconds -> (long)

How long, in seconds, for the canary to continue making regular runs according to the schedule in the Expression value. If you specify 0, the canary continues making runs until you stop it. If you omit this field, the default of 0 is used.

Shorthand Syntax:

Expression=string,DurationInSeconds=long

JSON Syntax:

{
  "Expression": "string",
  "DurationInSeconds": long
}

--run-config (structure)

A structure that contains the configuration for individual canary runs, such as timeout value.

TimeoutInSeconds -> (integer)

How long the canary is allowed to run before it must stop. If you omit this field, the frequency of the canary is used as this value, up to a maximum of 14 minutes.

MemoryInMB -> (integer)

The maximum amount of memory available to the canary while it is running, in MB. The value you specify must be a multiple of 64.

Shorthand Syntax:

TimeoutInSeconds=integer,MemoryInMB=integer

JSON Syntax:

{
  "TimeoutInSeconds": integer,
  "MemoryInMB": integer
}

--success-retention-period-in-days (integer)

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.

--failure-retention-period-in-days (integer)

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.

--runtime-version (string)

Specifies the runtime version to use for the canary. Currently, the only valid value is syn-1.0 . For more information about runtime versions, see Canary Runtime Versions .

--vpc-config (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 .

SubnetIds -> (list)

The IDs of the subnets where this canary is to run.

(string)

SecurityGroupIds -> (list)

The IDs of the security groups for this canary.

(string)

Shorthand Syntax:

SubnetIds=string,string,SecurityGroupIds=string,string

JSON Syntax:

{
  "SubnetIds": ["string", ...],
  "SecurityGroupIds": ["string", ...]
}

--tags (map)

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.

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.
