Method Details

start

public void start()

Description copied from interface: InstanceMetadataContext

Starts this InstanceMetadataContext.

Specified by:

start in interface InstanceMetadataContext

stop

public void stop()

Description copied from interface: InstanceMetadataContext

Specified by:

stop in interface InstanceMetadataContext

getNodeIds

public Set<NodeId> getNodeIds()

Description copied from interface: InstanceMetadataContext

Gets all NodeIds housed within the instance.

Specified by:

getNodeIds in interface InstanceMetadataContext

Returns:

the Set<NodeId> of all running and active nodes on the instance

getInstanceQuality

public double getInstanceQuality()

Description copied from interface: InstanceMetadataContext

Represents the instance's current load factor. This returns a double in the range of [0, 1], with the higher number representing a greater load. Load represents a single average measurement of how loaded the system is and this number may not necessary equate to CPU load.

Specified by:

getInstanceQuality in interface InstanceMetadataContext

Returns:

the instance's load

getInstanceMetadataAsync
