Overview

Rule that controls how a fleet is scaled. Scaling policies are uniquely identified by the combination of name and fleet ID.

Operations related to fleet capacity scaling include:

Instance Attribute Summary collapse

Instance Attribute Details

#comparison_operatorString

Comparison operator to use when measuring a metric against the threshold value.

Possible values:

  • GreaterThanOrEqualToThreshold
  • GreaterThanThreshold
  • LessThanThreshold
  • LessThanOrEqualToThreshold

Returns:

  • (String)

    Comparison operator to use when measuring a metric against the threshold value.

#evaluation_periodsInteger

Length of time (in minutes) the metric must be at or beyond the threshold before a scaling event is triggered.

Returns:

  • (Integer)

    Length of time (in minutes) the metric must be at or beyond the threshold before a scaling event is triggered.

#fleet_idString

Unique identifier for a fleet that is associated with this scaling policy.

Returns:

  • (String)

    Unique identifier for a fleet that is associated with this scaling policy.

#metric_nameString

Name of the Amazon GameLift-defined metric that is used to trigger a scaling adjustment. For detailed descriptions of fleet metrics, see Monitor Amazon GameLift with Amazon CloudWatch.

  • ActivatingGameSessions -- Game sessions in the process of being created.

  • ActiveGameSessions -- Game sessions that are currently running.

  • ActiveInstances -- Fleet instances that are currently running at least one game session.

  • AvailableGameSessions -- Additional game sessions that fleet could host simultaneously, given current capacity.

  • AvailablePlayerSessions -- Empty player slots in currently active game sessions. This includes game sessions that are not currently accepting players. Reserved player slots are not included.

  • CurrentPlayerSessions -- Player slots in active game sessions that are being used by a player or are reserved for a player.

  • IdleInstances -- Active instances that are currently hosting zero game sessions.

  • PercentAvailableGameSessions -- Unused percentage of the total number of game sessions that a fleet could host simultaneously, given current capacity. Use this metric for a target-based scaling policy.

  • PercentIdleInstances -- Percentage of the total number of active instances that are hosting zero game sessions.

  • QueueDepth -- Pending game session placement requests, in any queue, where the current fleet is the top-priority destination.

  • WaitTime -- Current wait time for pending game session placement requests, in any queue, where the current fleet is the top-priority destination.

Returns:

  • (String)

    Name of the Amazon GameLift-defined metric that is used to trigger a scaling adjustment.

#nameString

Descriptive label that is associated with a scaling policy. Policy names do not need to be unique.

Returns:

  • (String)

    Descriptive label that is associated with a scaling policy.

#policy_typeString

Type of scaling policy to create. For a target-based policy, set the parameter MetricName to \'PercentAvailableGameSessions\' and specify a TargetConfiguration. For a rule-based policy set the following parameters: MetricName, ComparisonOperator, Threshold, EvaluationPeriods, ScalingAdjustmentType, and ScalingAdjustment.

Possible values:

  • RuleBased
  • TargetBased

Returns:

  • (String)

    Type of scaling policy to create.

#scaling_adjustmentInteger

Amount of adjustment to make, based on the scaling adjustment type.

Returns:

  • (Integer)

    Amount of adjustment to make, based on the scaling adjustment type.

#scaling_adjustment_typeString

Type of adjustment to make to a fleet\'s instance count (see FleetCapacity):

  • ChangeInCapacity -- add (or subtract) the scaling adjustment value from the current instance count. Positive values scale up while negative values scale down.

  • ExactCapacity -- set the instance count to the scaling adjustment value.

  • PercentChangeInCapacity -- increase or reduce the current instance count by the scaling adjustment, read as a percentage. Positive values scale up while negative values scale down.

    Possible values:

    • ChangeInCapacity
    • ExactCapacity
    • PercentChangeInCapacity

Returns:

  • (String)

    Type of adjustment to make to a fleet\'s instance count (see FleetCapacity):.

#statusString

Current status of the scaling policy. The scaling policy can be in force only when in an ACTIVE status. Scaling policies can be suspended for individual fleets (see StopFleetActions; if suspended for a fleet, the policy status does not change. View a fleet\'s stopped actions by calling DescribeFleetCapacity.

  • ACTIVE -- The scaling policy can be used for auto-scaling a fleet.

  • UPDATE_REQUESTED -- A request to update the scaling policy has been received.

  • UPDATING -- A change is being made to the scaling policy.

  • DELETE_REQUESTED -- A request to delete the scaling policy has been received.

  • DELETING -- The scaling policy is being deleted.

  • DELETED -- The scaling policy has been deleted.

  • ERROR -- An error occurred in creating the policy. It should be removed and recreated.

    Possible values:

    • ACTIVE
    • UPDATE_REQUESTED
    • UPDATING
    • DELETE_REQUESTED
    • DELETING
    • DELETED
    • ERROR

Returns:

  • (String)

    Current status of the scaling policy.

#target_configurationTypes::TargetConfiguration

Object that contains settings for a target-based scaling policy.

Returns:

#thresholdFloat

Metric value used to trigger a scaling event.

Returns:

  • (Float)

    Metric value used to trigger a scaling event.
