Constructor Detail

AutomaticCapacityScaleConfig

public AutomaticCapacityScaleConfig()
Default constructor


AutomaticCapacityScaleConfig

public AutomaticCapacityScaleConfig(Map<String,String> properties)
Method Detail

getProperties

public Map<String,String> getProperties()
Description copied from interface: BeanConfig
Get the String key-value pairs properties used to configure this bean.

Specified by:
getProperties in interface BeanConfig
Returns:
the properties used to configure this bean object.

setProperties

public void setProperties(Map<String,String> properties)
Description copied from interface: BeanConfig
Set with String key-value pairs to configure properties belonging to this bean. Overrides all previously set properties.

Specified by:
setProperties in interface BeanConfig
Parameters:
properties - the properties to configure this bean object.

getBeanClassName

public String getBeanClassName()
Description copied from interface: BeanConfig
The Bean implementation class name corresponding to this BeanConfig.

Specified by:
getBeanClassName in interface BeanConfig
Returns:
the name of the admin Bean implementation class.

getMaxConcurrentRelocationsPerMachine

public int getMaxConcurrentRelocationsPerMachine()
Specified by:
getMaxConcurrentRelocationsPerMachine in interface ScaleStrategyConfig

setMaxConcurrentRelocationsPerMachine

public void setMaxConcurrentRelocationsPerMachine(int maxNumberOfConcurrentRelocationsPerMachine)
Description copied from interface: ScaleStrategyConfig
Specifies the number of processing unit instance relocations each machine can handle concurrently. Relocation requires network and CPU resources, and too many concurrent relocations per machine may degrade its performance temporarily. The data recovery running as part of the relocation uses by default 4 threads. So the total number of threads is 4 multiplied by the specified value. By setting this value higher than 1, processing unit rebalancing completes faster, by using more machine cpu and network resources. Default value is 1. This is an advanced property setting.

Specified by:
setMaxConcurrentRelocationsPerMachine in interface ScaleStrategyConfig

setPollingIntervalSeconds

public void setPollingIntervalSeconds(int pollingTimeIntervalSeconds)
Description copied from interface: ScaleStrategyConfig
Sets the polling interval in which the scale strategy SLA is monitored and enforced.

Specified by:
setPollingIntervalSeconds in interface ScaleStrategyConfig
Parameters:
pollingTimeIntervalSeconds - - the polling interval in seconds

getPollingIntervalSeconds

public int getPollingIntervalSeconds()
Specified by:
getPollingIntervalSeconds in interface ScaleStrategyConfig

isAtMostOneContainerPerMachine

public boolean isAtMostOneContainerPerMachine()
Specified by:
isAtMostOneContainerPerMachine in interface ScaleStrategyConfig

setAtMostOneContainerPerMachine

public void setAtMostOneContainerPerMachine(boolean atMostOneContainerPerMachine)
Description copied from interface: ScaleStrategyConfig
When set to true, at most one Grid Service Container for this Processing Unit is started per machine.

Specified by:
setAtMostOneContainerPerMachine in interface ScaleStrategyConfig

setStatisticsPollingIntervalSeconds

public void setStatisticsPollingIntervalSeconds(int statisticsPollingIntervalSeconds)
Sets the polling rate in which statistics are gathered.


getStatisticsPollingIntervalSeconds

public long getStatisticsPollingIntervalSeconds()

setCooldownAfterScaleOutSeconds

public void setCooldownAfterScaleOutSeconds(long cooldownAfterInstanceAddedSeconds)
Sets the number of seconds after a ProcessingUnitInstance is added and the ProcessingUnit.getStatus() is DeploymentStatus.INTACT that all scaling rules are disabled. Must be equal or bigger than setStatisticsPollingIntervalSeconds(int)

Sets the minimum scale capacity per agent zone that the @{link ProcessingUnit is deployed with. The result of a scaling rule result that increases capacity will never breach the minimum scale capacity per agent zone. This attribute should be used together with setGridServiceAgentZonesAware(boolean) enabled.


getMaxCapacityPerZone

public CapacityRequirementsConfig getMaxCapacityPerZone()

setMaxCapacityPerZone

public void setMaxCapacityPerZone(CapacityRequirementsConfig maxCapacityPerZone)
Sets the maximum scale capacity per agent zone that the @{link ProcessingUnit is deployed with. The result of a scaling rule result that increases capacity will never breach the maximum scale capacity per agent zone. This attribute should be used together with setGridServiceAgentZonesAware(boolean) enabled.

getRules

public AutomaticCapacityScaleRuleConfig[] getRules()

getMaxCapacity

public CapacityRequirementsConfig getMaxCapacity()

setInitialCapacity

public void setInitialCapacity(CapacityRequirementsConfig initialCapacity)

public boolean isGridServiceAgentZonesAware()
Specified by:
isGridServiceAgentZonesAware in interface ScaleStrategyAgentZonesAwareConfig

setGridServiceAgentZonesAware

public void setGridServiceAgentZonesAware(boolean enableAgentZonesAware)
Description copied from interface: ScaleStrategyAgentZonesAwareConfig
By default disabled, which means that the following machines: - Machines started due to failover of another machine. - Machines started by AutomaticCapacityScaleRuleConfig sue to threshold breach are started with a Grid Service Agent zones as described in #getGridServiceAgentZones() When enabled, these machines are started with the same ExactZonesConfig as the failed machine, or the same ExactZonesConfig as the machines whose threshold was breached.
