Clickhouse Keeper prometheus endpoint setup

[noobHappylife]

Is there any example that shows how to setup the clickhouse keeper with proper prometheus metrics endpoint?

I've tried adding the following annotation to the podTemplates:

annotations:
  prometheus.io/port: "7000"
  prometheus.io/scrape: "true"

and apply the grafanadashboard with the following.

apiVersion: grafana.integreatly.org/v1beta1
kind: GrafanaDashboard
metadata:
  name: clickhouse-keeper-dashboard
  namespace: clickhouse-operator-system
spec:
  resyncPeriod: 30s
  instanceSelector:
    matchLabels:
      dashboards: grafana
  allowCrossNamespaceImport: true
  configMapRef:
    name: clickhouse-operator-altinity-clickhouse-operator-dashboards
    key: ClickHouseKeeper_dashboard.json

However, on grafana what I see is all "error". While the clickhouse operator and queries dashboard is working fine.
