Arguments

:: CloudWatchAlarmDefinition	`$sel:cloudWatchAlarmDefinition:ScalingTrigger'`
-> ScalingTrigger

Create a value of ScalingTrigger with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:cloudWatchAlarmDefinition:ScalingTrigger', scalingTrigger_cloudWatchAlarmDefinition - The definition of a CloudWatch metric alarm. When the defined alarm conditions are met along with other trigger parameters, scaling activity begins.

scalingTrigger_cloudWatchAlarmDefinition :: Lens' ScalingTrigger CloudWatchAlarmDefinition Source #

The definition of a CloudWatch metric alarm. When the defined alarm conditions are met along with other trigger parameters, scaling activity begins.
