Package org.apache.pekko.cluster.metrics

Class CpuMetricsSelector$

java.lang.Object

org.apache.pekko.cluster.metrics.CapacityMetricsSelector

org.apache.pekko.cluster.metrics.CpuMetricsSelector$

All Implemented Interfaces:

java.io.Serializable, MetricsSelector, 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.

capacity

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).
