Reference Document : Kubernetes Component SLI Metrics | Kubernetes

I have created a job in the Prometheus Helm values file to scrape Kubernetes Component SLI metrics. When I execute the command kubectl get --raw /metrics/slis, I receive the following two metrics: kubernetes_healthcheck and kubernetes_healthchecks_total.

According to the reference document, this metric endpoint is exposed on the serving HTTPS port of each component, specifically at the path /metrics/slis. I have created a service account with cluster view role access, and I can see that my target appears healthy in the Targets and Service Discovery sections of the Prometheus UI. However, I am unable to see the related metrics (kubernetes_healthcheck and kubernetes_healthchecks_total) when querying in the Prometheus UI.

While I can successfully retrieve these metrics using the command kubectl get --raw /metrics/slis, I encounterd an issue with the following curl command:
curl -k -H “Authorization: Bearer ” https://:10250/metrics/slis

The request authenticates correctly, but I only see the last two lines as comments and not the expected metrics. In contrast, when I execute:

curl -k -H “Authorization: Bearer ” https://:10250/metrics/cadvisor

I can see metrics related to cAdvisor, but the /metrics/slis path returns nothing and does not produce any error messages. I have also tried /metrics/slis request by giving cluster admin role service account token but still facing the same issue.

For your information, I am using EKS (1.29) with self-managed nodes.
