Class CpuMetricsSelector


  • public class CpuMetricsSelector
    extends java.lang.Object
    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.
