[T2 instances] The number of CPU credits spent by the instance for CPU utilization. One CPU
credit equals one vCPU running at 100% utilization for one minute or an equivalent
combination of vCPUs, utilization, and time (for example, one vCPU running at 50% utilization
for two minutes or two vCPUs running at 25% utilization for two minutes).
CPU credit metrics are available at a five-minute frequency only. If you specify a period
greater than five minutes, use the Sum statistic instead of the Average statistic.
