Query Explanation

The query computes, for each container (grouped by container, pod, and namespace), the fraction of CPU CFS periods that were throttled in the last 5 minutes: sum(increase(container_cpu_cfs_throttled_periods_total{container!=""}[5m])) / sum(increase(container_cpu_cfs_periods_total[5m])). If this throttling ratio exceeds 25 % (i.e., >0.25), the Container high throttle rate alert fires, indicating the container is being heavily throttled.
