cadvisor: No targets visible in prometheus-ui about helm-charts HOT 2 CLOSED

Thanks for the fast response and the helpful suggestions. Option 1 totally works for me. Thank you!

The order is correct, but you use the default configuration for both charts which are not compatible.

There's a label-selector to match installed servicemonitors. This selector serviceMonitorSelector (from the values.yaml of the kube-prometheus-stack chart) is set to release: monitoring in your case by default. (monitoring because you named your stack-installation that way). This means that all servicemonitors you install need a label release: monitoring to be detected by the prometheus-operator.

You have two options:

1. Set the serviceMonitorSelectorNilUsesHelmValues parameter from the kube-prometheus-stack to false, this will disable the default selection behaviour. All servicemonitors are detected now.
2. There needs to be a label at the cadvisor servicemonitor which matches the expected selector. Unfortunately there's no way to add custom-labels to the cadvisor servicemonitor right now, so a chart-update would be needed to achieve this.
