Class CpuMetricsSelector$

  • All Implemented Interfaces:
    MetricsSelector, java.io.Serializable, scala.Equals, scala.Product

    public class CpuMetricsSelector$
    extends CapacityMetricsSelector
    implements scala.Product, java.io.Serializable
    MetricsSelector that uses the combined CPU time metrics and stolen CPU time metrics. In modern Linux kernels: CpuCombined + CpuStolen + CpuIdle = 1.0 or 100%. Combined CPU is sum of User + Sys + Nice + Wait times, as percentage. Stolen CPU is the amount of CPU taken away from this virtual machine by the hypervisor, as percentage.

    Low CPU capacity => small node 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).
