cadvisor 有两个指标container_cpu_cfs_throttled_seconds_total和container_cpu_cfs_throttled_periods_total

我很困惑这是什么意思..

我找了两个解释一下？

1. 容器以 cpu 限制运行，当容器 cpu 超过限制时，容器将被“节流”并向container_cpu_cfs_throttled_seconds_total添加时间

   that means ?
    (1). only container cpu over limit, rate(container_cpu_cfs_throttled_seconds_total) > 0. 
    (2). we can use this metrics to alert container cpu over limit ...

2. 当主机处于沉重的 cpu 压力下时，它将使用 POD QoS（保证 > 突发 > 尽力而为）“节流”容器......

   that means ?
    (1). container_cpu_cfs_throttled_seconds_total will add has no relate with how many cpu container used and cpu limit ..
    (2). this metrics can not to alert container cpu over limit ..
