Asked by HelixJeremy

Hi, I installed the one click “Kubernetes Monitoring Stack” to my cluster justnow. I tried to check some metrics from the grafana dashboard but the prometheus scraping_interval config is too slow (defaults to 30s) for my usecase.

More explanation regarding the scraping_interval I talked about can be found here https://prometheus.io/docs/prometheus/latest/configuration/configuration/.

I have tried editing various service monitor but was not successful. Is there anything I can try to change the setting? Any assistance would be much appreciated. Thanks!

Hello, I have working on this package as well. After a lot of grief, it is my recommendation that you ONLY edit, the values.yaml file. This is designed to expose these configurable values. Then do a helm update. What is the values.yaml file you ask? Well go here: https://helm.sh/docs/helm/helm_show_values/

pipe this to a file, called values.yaml. Then edit the this file with what you need to change. Then update the installation. This will overwrite the default values in the chart with your changes.

helm upgrade my-prometheus prometheus-community/kube-prometheus-stack --namespace monitoring -f values.yaml

Hope this helps
