```
public abstract class CapacityMetricsSelector
extends java.lang.Object
implements MetricsSelector
```
A MetricsSelector producing weights from remaining capacity. The weights are typically proportional to the remaining capacity.

- Method Detail
  - capacity
```
public abstract scala.collection.immutable.Map<Address,java.lang.Object> capacity(scala.collection.immutable.Set<NodeMetrics> nodeMetrics)
```
    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).
  - weights
```
public scala.collection.immutable.Map<Address,java.lang.Object> weights(scala.collection.immutable.Map<Address,java.lang.Object> capacity)
```
    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.
  - weights
```
public scala.collection.immutable.Map<Address,java.lang.Object> weights(scala.collection.immutable.Set<NodeMetrics> nodeMetrics)
```
    The weights per address, based on the capacity produced by the nodeMetrics.
