cAdvisor on Prometheus with Kubernetes

I can’t get Prometheus to pick up on my cAdvisor metrics on DOKS. It shows as a successful scrape on the Prometheus dashboard, but I can’t get any container_* metrics to show up in the query. Any ideas?

Here’s my job config for cadvisor:

    - job_name: kubernetes-cadvisor
      honor_timestamps: true
      scrape_interval: 15s
      scrape_timeout: 10s
      metrics_path: /metrics
      scheme: https
      bearer_token_file: /var/run/secrets/
        ca_file: /var/run/secrets/
        insecure_skip_verify: true
      - role: node
      - separator: ;
        regex: __meta_kubernetes_node_label_(.+)
        replacement: $1
        action: labelmap
      - source_labels: [__address__]
        separator: ;
        regex: ([^:]+)(?::\d+)?
        target_label: __address__
        replacement: $1:10250
        action: replace
      - separator: ;
        regex: (.*)
        target_label: __metrics_path__
        replacement: /metrics/cadvisor
        action: replace
      - source_labels: [namespace]
        separator: ;
        regex: ^$
        replacement: $1
        action: drop
      - source_labels: [pod_name]
        separator: ;
        regex: ^$
        replacement: $1
        action: drop

I’ve also tried the metric path as /metrics/cadvisor like some issues of Github have suggested.

Accepted Answer

pod_name and container_name were removed from cadvisor on 1.16. The metric_relabel_configs on pod_name is dropping the metrics. Try replace it with just pod.


try using /metrics.It might work.

You can debug the target by going to the UI > Status > Targets. See if the target address is correct.
