Class SystemLoadAverageMetricsSelector

java.lang.Object
  akka.cluster.routing.CapacityMetricsSelector
      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.
