Properties for a canary.
- Parameters:
runtime (
Runtime
) – Specify the runtime version to use for the canary.test (
Test
) – The type of test that you want your canary to run. UseTest.custom()
to specify the test to run.artifacts_bucket_lifecycle_rules (
Optional
[Sequence
[Union
[LifecycleRule
,Dict
[str
,Any
]]]]) – Lifecycle rules for the generated canary artifact bucket. Has no effect if a bucket is passed toartifactsBucketLocation
. If you pass a bucket toartifactsBucketLocation
, you can add lifecycle rules to the bucket itself. Default: - no rules applied to the generated bucket.artifacts_bucket_location (
Union
[ArtifactsBucketLocation
,Dict
[str
,Any
],None
]) – The s3 location that stores the data of the canary runs. Default: - A new s3 bucket will be created without a prefix.canary_name (
Optional
[str
]) – The name of the 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 name. The canary name makes up part of the canary ARN, which is included in outbound calls over the internet. Default: - A unique name will be generated from the construct IDcleanup (
Optional
[Cleanup
]) – Specify the underlying resources to be cleaned up when the canary is deleted. UsingCleanup.LAMBDA
will create a Custom Resource to achieve this. Default: Cleanup.NOTHINGenvironment_variables (
Optional
[Mapping
[str
,str
]]) – Key-value pairs that the Synthetics caches and makes available for your canary scripts. Use environment variables to apply configuration changes, such as test and production environment configurations, without changing your Canary script source code. Default: - No environment variables.failure_retention_period (
Optional
[Duration
]) – How many days should failed runs be retained. Default: Duration.days(31)role (
Optional
[IRole
]) – Canary execution role. This is the role that will be assumed by the canary upon execution. It controls the permissions that the canary will have. The role must be assumable by the AWS Lambda service principal. If not supplied, a role will be created with all the required permissions. If you provide a Role, you must add the required permissions. Default: - A unique role will be generated for this canary. You can add permissions to roles by calling ‘addToRolePolicy’.schedule (
Optional
[Schedule
]) – Specify the schedule for how often the canary runs. For example, if you setschedule
torate(10 minutes)
, then the canary will run every 10 minutes. You can set the schedule withSchedule.rate(Duration)
(recommended) or you can specify an expression usingSchedule.expression()
. Default: ‘rate(5 minutes)’security_groups (
Optional
[Sequence
[ISecurityGroup
]]) – The list of security groups to associate with the canary’s network interfaces. You must providevpc
when using this prop. Default: - If the canary is placed within a VPC and a security group is not specified a dedicated security group will be created for this canary.start_after_creation (
Optional
[bool
]) – Whether or not the canary should start after creation. Default: truesuccess_retention_period (
Optional
[Duration
]) – How many days should successful runs be retained. Default: Duration.days(31)time_to_live (
Optional
[Duration
]) – How long the canary will be in a ‘RUNNING’ state. For example, if you settimeToLive
to be 1 hour andschedule
to berate(10 minutes)
, your canary will run at 10 minute intervals for an hour, for a total of 6 times. Default: - no limitvpc (
Optional
[IVpc
]) – The VPC where this canary is run. Specify this if the canary needs to access resources in a VPC. Default: - Not in VPCvpc_subnets (
Union
[SubnetSelection
,Dict
[str
,Any
],None
]) – Where to place the network interfaces within the VPC. You must providevpc
when using this prop. Default: - the Vpc default strategy if not specified

Attributes
- artifacts_bucket_lifecycle_rules
Lifecycle rules for the generated canary artifact bucket.
Has no effect if a bucket is passed to
artifactsBucketLocation
. If you pass a bucket toartifactsBucketLocation
, you can add lifecycle rules to the bucket itself.- Default:
no rules applied to the generated bucket.
- artifacts_bucket_location
The s3 location that stores the data of the canary runs.
- Default:
A new s3 bucket will be created without a prefix.
- canary_name
The name of the 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 name. The canary name makes up part of the canary ARN, which is included in outbound calls over the internet.
- Default:
A unique name will be generated from the construct ID
- See:
https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/servicelens_canaries_security.html
- cleanup
Specify the underlying resources to be cleaned up when the canary is deleted.
Using
Cleanup.LAMBDA
will create a Custom Resource to achieve this.- Default:
Cleanup.NOTHING
- environment_variables
Key-value pairs that the Synthetics caches and makes available for your canary scripts.
Use environment variables to apply configuration changes, such as test and production environment configurations, without changing your Canary script source code.
- Default:
No environment variables.
- failure_retention_period
How many days should failed runs be retained.
- Default:
Duration.days(31)
- role
