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

cAdvisor with Prometheus and Grafana Prometheus is a metrics server that scrapes and stores metrics from different sources, including Kubernetes nodes and individual containers. Since you want to collect the metrics related to containers, you'll be using cAdvisor in this example.
cAdvisor (Container Advisor) provides container users an understanding of the resource usage and performance characteristics of their running containers. It is a running daemon that collects, aggregates, processes, and exports information about running containers.
In order to get the metric container_cpu_load_average_10s, the cAdvisor must run with the option
--enable_load_reader=true
which is set fo false by default. This is described here.
