AWS::Synthetics::Canary Schedule

This structure specifies how often a canary is to make runs and the date and time when it should stop making runs.


To declare this entity in your AWS CloudFormation template, use the following syntax:


{ "DurationInSeconds" : String, "Expression" : String }


DurationInSeconds: String Expression: String



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.

Required: No

Type: String

Update requires: No interruption


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.
