- container_cpu_cfs_periods_total：container生命周期中度过的cpu周期总数
- container_cpu_cfs_throttled_periods_total：container生命周期中度过的受限的cpu周期总数
- sum by (container, pod, namespace) (increase(container_cpu_cfs_throttled_periods_total{container!=””}[5m])) / sum by (container, pod, namespace) (increase(container_cpu_cfs_periods_total[5m])) > (25 / 100)
