cAdvisor prometheus integration returns container_cpu_load_average_10s as 0

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

Solution

  • 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.
