public AutoscalingPolicy()









Method Detail





getCoolDownPeriodSec
public Integer getCoolDownPeriodSec()
The number of seconds that your application takes to initialize on a VM instance. This is
 referred to as the [initialization period](/compute/docs/autoscaler#cool_down_period).
 Specifying an accurate initialization period improves autoscaler decisions. For example, when
 scaling out, the autoscaler ignores data from VMs that are still initializing because those VMs
 might not yet represent normal usage of your application. The default initialization period is
 60 seconds. Initialization periods might vary because of numerous factors. We recommend that
 you test how long your application takes to initialize. To do this, create a VM and time your
 application's startup process.

Returns:
value or null for none








setCoolDownPeriodSec
public AutoscalingPolicy setCoolDownPeriodSec(Integer coolDownPeriodSec)
The number of seconds that your application takes to initialize on a VM instance. This is
 referred to as the [initialization period](/compute/docs/autoscaler#cool_down_period).
 Specifying an accurate initialization period improves autoscaler decisions. For example, when
 scaling out, the autoscaler ignores data from VMs that are still initializing because those VMs
 might not yet represent normal usage of your application. The default initialization period is
 60 seconds. Initialization periods might vary because of numerous factors. We recommend that
 you test how long your application takes to initialize. To do this, create a VM and time your
 application's startup process.

Parameters:
coolDownPeriodSec - coolDownPeriodSec or null for none








getCpuUtilization
public AutoscalingPolicyCpuUtilization getCpuUtilization()
Defines the CPU utilization policy that allows the autoscaler to scale based on the average CPU
 utilization of a managed instance group.

Returns:
value or null for none








setCpuUtilization
public AutoscalingPolicy setCpuUtilization(AutoscalingPolicyCpuUtilization cpuUtilization)
Defines the CPU utilization policy that allows the autoscaler to scale based on the average CPU
 utilization of a managed instance group.

Parameters:
cpuUtilization - cpuUtilization or null for none








getCustomMetricUtilizations
public List<AutoscalingPolicyCustomMetricUtilization> getCustomMetricUtilizations()
Configuration parameters of autoscaling based on a custom metric.

Returns:
value or null for none








setCustomMetricUtilizations
public AutoscalingPolicy setCustomMetricUtilizations(List<AutoscalingPolicyCustomMetricUtilization> customMetricUtilizations)
Configuration parameters of autoscaling based on a custom metric.

Parameters:
customMetricUtilizations - customMetricUtilizations or null for none








getLoadBalancingUtilization
public AutoscalingPolicyLoadBalancingUtilization getLoadBalancingUtilization()
Configuration parameters of autoscaling based on load balancer.

Returns:
value or null for none








setLoadBalancingUtilization
public AutoscalingPolicy setLoadBalancingUtilization(AutoscalingPolicyLoadBalancingUtilization loadBalancingUtilization)
Configuration parameters of autoscaling based on load balancer.

Parameters:
loadBalancingUtilization - loadBalancingUtilization or null for none








getMaxNumReplicas
public Integer getMaxNumReplicas()
The maximum number of instances that the autoscaler can scale out to. This is required when
 creating or updating an autoscaler. The maximum number of replicas must not be lower than
 minimal number of replicas.

Returns:
value or null for none








setMaxNumReplicas
public AutoscalingPolicy setMaxNumReplicas(Integer maxNumReplicas)
The maximum number of instances that the autoscaler can scale out to. This is required when
 creating or updating an autoscaler. The maximum number of replicas must not be lower than
 minimal number of replicas.

Parameters:
maxNumReplicas - maxNumReplicas or null for none








getMinNumReplicas
public Integer getMinNumReplicas()
The minimum number of replicas that the autoscaler can scale in to. This cannot be less than 0.
 If not provided, autoscaler chooses a default value depending on maximum number of instances
 allowed.

Returns:
value or null for none








setMinNumReplicas
public AutoscalingPolicy setMinNumReplicas(Integer minNumReplicas)
The minimum number of replicas that the autoscaler can scale in to. This cannot be less than 0.
 If not provided, autoscaler chooses a default value depending on maximum number of instances
 allowed.

Parameters:
minNumReplicas - minNumReplicas or null for none








getMode
public String getMode()
Defines the operating mode for this policy. The following modes are available: - OFF: Disables
 the autoscaler but maintains its configuration. - ONLY_SCALE_OUT: Restricts the autoscaler to
 add VM instances only. - ON: Enables all autoscaler activities according to its policy. For
 more information, see "Turning off or restricting an autoscaler"

Returns:
value or null for none








setMode
public AutoscalingPolicy setMode(String mode)
Defines the operating mode for this policy. The following modes are available: - OFF: Disables
 the autoscaler but maintains its configuration. - ONLY_SCALE_OUT: Restricts the autoscaler to
 add VM instances only. - ON: Enables all autoscaler activities according to its policy. For
 more information, see "Turning off or restricting an autoscaler"

Parameters:
mode - mode or null for none








getScaleInControl
public AutoscalingPolicyScaleInControl getScaleInControl()

Returns:
value or null for none








setScaleInControl

Parameters:
scaleInControl - scaleInControl or null for none








getScalingSchedules
public Map<String,AutoscalingPolicyScalingSchedule> getScalingSchedules()
Scaling schedules defined for an autoscaler. Multiple schedules can be set on an autoscaler,
 and they can overlap. During overlapping periods the greatest min_required_replicas of all
 scaling schedules is applied. Up to 128 scaling schedules are allowed.

Returns:
value or null for none








setScalingSchedules
public AutoscalingPolicy setScalingSchedules(Map<String,AutoscalingPolicyScalingSchedule> scalingSchedules)

 and they can overlap. During overlapping periods the greatest min_required_replicas of all
 scaling schedules is applied. Up to 128 scaling schedules are allowed.

Parameters:

set
public AutoscalingPolicy set(String fieldName,
                             Object value)

Overrides:
set in class com.google.api.client.json.GenericJson








clone
public AutoscalingPolicy clone()

Overrides:
clone in class com.google.api.client.json.GenericJson
