Component: charts, salt

Why this is needed:
To be able to correctly monitor Dex processes.

What should be done:
Expose Dex metrics, then scrape them using Prometheus.

Implementation proposal (strongly recommended):

  • Tune the Dex Helm chart configuration file charts/dex.yaml to enable metrics
telemetry: true
  • Deploy a ServiceMonitor object to expose the Dex /metrics path to Prometheus.

Test plan:
