我使用cAdvisor在prometheus中使用以下表达式来监控容器的CPU使用率: (sum(rate(container_cpu_usage_seconds_total[3m])) BY (instance, name) * 100) > 80 我的一个容器经常触发此警报,因为它实际上使用了超过80%的CPU,但仅在单个内核上。我的主机有多个核心,我想用这个百分比除以核心的数量。我可以看到cAdviso...

irate(container_cpu_usage_seconds_total{container_name='prometheus-server',cpu='cpu00'}[5m]) Scrape interval is 1m, that's true. However, first query shows that the metrics are every 15s, so rate[1m] should work. Had a look at prometheus-query. It looks like the default step value is...
In case of scarce crane resource, a relevant performance measure is the crane utilization rate (util), defined by the ratio of a crane’s productive time and the total vessel handling time. Another such measure is the throughput of cranes (through) defined by the number of container moves ...
