      extended by akka.cluster.routing.SystemLoadAverageMetricsSelector$
All Implemented Interfaces:
MetricsSelector, java.io.Serializable, scala.Equals, scala.Product

public class SystemLoadAverageMetricsSelector$
extends CapacityMetricsSelector
implements scala.Product, scala.Serializable

MetricsSelector that uses the system load average metrics. System load average is OS-specific average load on the CPUs in the system, for the past 1 minute. The system is possibly nearing a bottleneck if the system load average is nearing number of cpus/cores. Low load average capacity => small weight.

public scala.collection.immutable.Map<Address,java.lang.Object> capacity(scala.collection.immutable.Set<NodeMetrics> nodeMetrics)
Description copied from class: CapacityMetricsSelector
Remaining capacity for each node. The value is between 0.0 and 1.0, where 0.0 means no remaining capacity (full utilization) and 1.0 means full remaining capacity (zero utilization).
