Method Detail

status

public AutoScalingPolicyStatus status()

The status of an automatic scaling policy.

Returns:

The status of an automatic scaling policy.

constraints

public ScalingConstraints constraints()

The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.

Returns:

The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.

rules

public List<ScalingRule> rules()

The scale-in and scale-out rules that comprise the automatic scaling policy.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

Returns:

The scale-in and scale-out rules that comprise the automatic scaling policy.
