在 prometheus 中排除 Kubernetes 指标监控

Question

We are monitoring our Kubernetes clusters metrics through Prometheus. It is working fine but we dont want monitor all default metrics. Just want to monitor few selected metrics. How do I exclude unwanted metrics from prometheus.

We are using the below version K8:

1.18.6

Installed Prometheus usning helm chart:

helm repo add prometheus-community https://prometheus-community.github.io/helm-chart

helm search repo prometheus-community-new/prometheus

helm install prometheus-community/prometheus --generate-name --namespace prometheus

where should I disable these metrics in helm.

Thank you

With the commands you used, Helm will apply the defaults as defined in the values.yaml of said chart. You want to redefine (replace) the jobs under serverFiles.prometheus.yml.scrape_configs by removing any jobs using the Kubernetes service discovery that you're not interested in and/or by adjusting the relabling directives to your needs.
