2021/10/01 - Synthetics - 4 updated api methods
Changes CloudWatch Synthetics now enables customers to choose a customer managed AWS KMS key or an Amazon S3-managed key instead of an AWS managed key (default) for the encryption of artifacts that the canary stores in Amazon S3. CloudWatch Synthetics also supports artifact S3 location updation now.

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 .

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.
Use cron(*expression* ) to specify a cron expression. You can't schedule a canary to wait for more than a year before running. For information about the syntax for cron expressions, see Scheduling canary runs using cron .
DurationInSeconds (integer) --

string
[REQUIRED]
The name of the canary that you want to update. To find the names of your canaries, use DescribeCanaries .
You cannot change the name of a canary that has already been created.
dict
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 bucket name here. Do not include 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 (bytes) --
If you input your canary script directly into the canary instead of referring to an S3 location, the value of this parameter is the base64-encoded contents of the .zip file that contains the script. It must be smaller than 256 Kb.
Handler (string) -- [REQUIRED]
The entry point to use for the source code when running the canary. This value must end with the string .handler . The string is limited to 29 characters or fewer.
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
string
Specifies the runtime version to use for the canary. For a list of valid runtime versions and for more information about runtime versions, see Canary Runtime Versions .
dict
A structure that contains information about how often the canary is to run, and when these runs are to stop.
Expression (string) -- [REQUIRED]
A rate expression or a cron expression that defines how often the canary is to run.
For a rate expression, 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.
Use cron(*expression* ) to specify a cron expression. You can't schedule a canary to wait for more than a year before running. For information about the syntax for cron expressions, see Scheduling canary runs using cron .
DurationInSeconds (integer) --
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.
dict
A structure that contains the timeout value that is used for each individual run of the canary.
TimeoutInSeconds (integer) --
How long the canary is allowed to run before it must stop. You can't set this time to be longer than the frequency of the runs of this canary.
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. This value must be a multiple of 64.
ActiveTracing (boolean) --
Specifies whether this canary is to use active X-Ray tracing when it runs. Active tracing enables this canary run to be displayed in the ServiceLens and X-Ray service maps even if the canary does not hit an endpoint that has X-Ray tracing enabled. Using X-Ray tracing incurs charges. For more information, see Canaries and X-Ray tracing .
You can enable active tracing only for canaries that use version syn-nodejs-2.0 or later for their canary runtime.
EnvironmentVariables (dict) --
Specifies the keys and values to use for any environment variables used in the canary script. Use the following format:
{ "key1" : "value1", "key2" : "value2", ...}
Keys must start with a letter and be at least two characters. The total size of your environment variables cannot exceed 4 KB. You can't specify any Lambda reserved environment variables as the keys for your environment variables. For more information about reserved keys, see Runtime environment variables .
