Monitor Container Load Average with Grafana Agent and Cadvisor (Docker Integration)

Grafana Alloy
1

Hi,

I’ve configured Docker integration on Grafana Cloud, utilizing Cadvisor and Grafana Agent to monitor Docker containers, and it’s been effective for most metrics. I’ve been referencing the metrics documented: Docker Integration Metrics.

However, I’m encountering challenges when trying to monitor the load average of individual containers. Specifically, the container_cpu_load_average_10s metric appears in Grafana, but it doesn’t seem to provide any values.

I’m aware that load average is typically a host-level metric, but I’m interested in approximating it for my containers. I came across these discussions related to the issue:

  • Issue 3706
  • Issue 1656 (github .com/grafana/agent/issues/1656)

Could someone please advise if there have been any recent developments on this topic? Is there a way to pass the load average metric to Grafana Agent for my Docker containers, or can you suggest an approach to approximate it using the existing setup?

I would greatly appreciate any guidance or recommendations on how to achieve this monitoring goal. Thank you!

I have the same issue.
When I check the endpoints in prometheus, I see an error message for cadvisor: label_value_length_limit exceeded (metric: container_cpu_load_average_10s, label name: container_label_org_opencontainers_image_descripti, value: "[syslog-ng](https://www.syslog-ng.com/products/ope", length: 230, limit: 200)
Perhaps you are experiencing a similar issue?
I haven’t figured out how to increae the limit or truncate the metrics
