NAME
Paws::ApplicationAutoScaling::PutScalingPolicy - Arguments for method PutScalingPolicy on Paws::ApplicationAutoScaling
DESCRIPTION
This class represents the parameters used for calling the method PutScalingPolicy on the Application Auto Scaling service. Use the attributes of this class as arguments to method PutScalingPolicy.
You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to PutScalingPolicy.
SYNOPSIS
my $application-autoscaling = Paws->service('ApplicationAutoScaling');
# To apply a scaling policy to an Amazon ECS service
# This example applies a scaling policy to an Amazon ECS service called web-app
# in the default cluster. The policy increases the desired count of the service
# by 200%, with a cool down period of 60 seconds.
my $PutScalingPolicyResponse = $application -autoscaling->PutScalingPolicy(
'PolicyName' => 'web-app-cpu-gt-75',
'PolicyType' => 'StepScaling',
'ResourceId' => 'service/default/web-app',
'ScalableDimension' => 'ecs:service:DesiredCount',
'ServiceNamespace' => 'ecs',
'StepScalingPolicyConfiguration' => {
'AdjustmentType' => 'PercentChangeInCapacity',
'Cooldown' => 60,
'StepAdjustments' => [
{
'MetricIntervalLowerBound' => 0,
'ScalingAdjustment' => 200
}
]
}
);
# Results:
my $PolicyARN = $PutScalingPolicyResponse->PolicyARN;
# Returns a L<Paws::ApplicationAutoScaling::PutScalingPolicyResponse> object.
# To apply a scaling policy to an Amazon EC2 Spot fleet
# This example applies a scaling policy to an Amazon EC2 Spot fleet. The policy
# increases the target capacity of the spot fleet by 200%, with a cool down
# period of 180 seconds.",
my $PutScalingPolicyResponse = $application -autoscaling->PutScalingPolicy(
'PolicyName' => 'fleet-cpu-gt-75',
'PolicyType' => 'StepScaling',
'ResourceId' =>
'spot-fleet-request/sfr-45e69d8a-be48-4539-bbf3-3464e99c50c3',
'ScalableDimension' => 'ec2:spot-fleet-request:TargetCapacity',

'StepScalingPolicyConfiguration' => {
'AdjustmentType' => 'PercentChangeInCapacity',
'Cooldown' => 180,
'StepAdjustments' => [
{
'MetricIntervalLowerBound' => 0,
'ScalingAdjustment' => 200
}
]
}
);
# Results:
my $PolicyARN = $PutScalingPolicyResponse->PolicyARN;
# Returns a L<Paws::ApplicationAutoScaling::PutScalingPolicyResponse> object.Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object.
