cAdvisor普罗米修斯集成返回container_cpu_load_average_10s为0 [英] cAdvisor prometheus integration returns container_cpu_load_average_10s as 0
问题描述
我已将Prometheus配置为从cAdvisor抓取指标.但是，度量标准"container_cpu_load_average_10s"仅返回0.我能够在cAdvisor Web UI下正确看到CPU度量标准，但Prometheus仅接收0.对于其他度量标准(如"container_cpu_system_seconds_total")，它工作正常.有人可以指出我是否在这里遗漏了什么?
I have configured Prometheus to scrape metrics from cAdvisor. However, the metric "container_cpu_load_average_10s" only returns 0. I am able to see the CPU metrics under the cAdvisor web UI correctly but Prometheus receives only 0. It is working fine for other metrics like "container_cpu_system_seconds_total". Could someone point if I am missing something here?

推荐答案
为了获取指标container_cpu_load_average_10s，cAdvisor必须与选项一起运行
In order to get the metric container_cpu_load_average_10s, the cAdvisor must run with the option
--enable_load_reader=true
，默认情况下设置为false.在此处中进行描述.
which is set fo false by default. This is described here.
