• CPU Ready Time in VMware and How to Interpret its Real Meaning
  • in ms, more core/vCPU will have higher CPU Ready Time
  • per vCPU, >5% is warning, >10% is critical (each vCPU count 100%, 4 vCPU = 400%)
  • host over subscription can affect this counter
  • ([CPU Ready ms value] / (20s * 1000)) * 100 = CPU Ready % value
