Notifications on degraded services, also Prometheus / Grafana?

[bmann]

There is an option to get email notification when apps go down.

I’ve been having degraded (yellow / restarting) core services - Postgres, MySQL, etc

Is there a way to get email notifications when those core services go down?

And — anyone have documentation on using Grafana or Prometheus to show stats for the Cloudron box where they are installled that might do something similar?
