abstract class CapacityMetricsSelector extends MetricsSelector

A MetricsSelector producing weights from remaining capacity. The weights are typically proportional to the remaining capacity.

Abstract Value Members

  1. abstract def capacity(nodeMetrics: Set[NodeMetrics]): Map[Address, Double]

    Remaining capacity for each node.

    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).

Concrete Value Members

  1. def weights(nodeMetrics: Set[NodeMetrics]): Map[Address, Int]

    The weights per address, based on the capacity produced by the nodeMetrics.

    The weights per address, based on the capacity produced by the nodeMetrics.

  2. def weights(capacity: Map[Address, Double]): Map[Address, Int]

    Converts the capacity values to weights.

    Converts the capacity values to weights. The node with lowest capacity gets weight 1 (lowest usable capacity is 1%) and other nodes gets weights proportional to their capacity compared to the node with lowest capacity.
