What happened?

from: https://docs.cilium.io/en/stable/operations/metrics/

When metrics are enabled, all Cilium components will have the following annotations. They can be used to signal Prometheus whether to scrape metrics:
prometheus.io/scrape: true
prometheus.io/port: 9962

The helm chart, however, has:

    {{- if not .Values.hubble.metrics.serviceMonitor.enabled }}
    prometheus.io/scrape: "true"
    prometheus.io/port: {{ .Values.hubble.metrics.port | quote }}
    {{- end }}

Which shows the annotation is only enabled in some cases.

Additional fields on how to use the cilium serviceMonitor (with prometheus-kube-stack helm chart) would be most welcome!
