问题
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?
Prometheus version: 2.1.0
Prometheus config:
scrape_configs:
- job_name: cadvisor
scrape_interval: 5s
metrics_path: /metrics
scheme: http
static_configs:
- targets:
- 172.17.0.2:8080
cAdvisor version: 0.29.0

In order to get the metric "container_cpu_load_average_10s" the cAdvisor must run with the option "--enable_load_reader=true", by default this option is set to false. This is described here enter link description here
