This structure specifies how often a canary is to make runs and the date and time when it should stop making runs.
Example
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as synthetics from '@aws-cdk/aws-synthetics';
const scheduleProperty: synthetics.CfnCanary.ScheduleProperty = {
expression: 'expression',
// the properties below are optional
durationInSeconds: 'durationInSeconds',
};
Properties
Name | Type | Description |
---|---|---|
expression | string | A rate expression or a cron expression that defines how often the canary is to run. |
duration | string | How long, in seconds, for the canary to continue making regular runs according to the schedule in the Expression value. |
expression
Type:
string
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?
Type:
string
(optional)
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.
