Database configuration

The Database configuration app is a single place in Grafana Cloud where you can self-serve manage settings for the databases behind your stack, instead of opening a support ticket for every change.

Access the Database configuration app

You need the Admin role on the stack to access the app.

To open the Database configuration app:

1. In your Grafana Cloud stack, in the main menu, expand Administration.
2. Select Database configurations.

The landing page shows a card for each database technology behind your stack:

• Logs (Loki) - available today. Select Configure to manage log ingestion limits such as retention, OTLP label mappings, and line truncation. Refer to Configure Loki settings.
• Traces (Tempo) - manage the Tempo metrics generator, which produces span metrics and service graph metrics from your traces. Refer to Configure Tempo traces metrics.
• Metrics (Mimir) and Profiles (Pyroscope) - shown as Coming soon. These aren’t configurable through the app yet.

How configuration changes are handled

Each database’s configuration page works a little differently, so check the specific topic for details before you make a change:

• Logs (Loki) uses a change-request model. When you submit a change, our engineering team manually reviews it before it takes effect - this can take up to two business days. The current configuration shows a pending, applied, or rejected status while your request is reviewed. Refer to Configure Loki settings for details.
• Traces (Tempo) uses a direct-save model. When you save a change, it applies to your live configuration immediately, and a badge shows whether the change has finished rolling out (Reconciling new configuration or Reconciled). There’s no manual review step. Refer to Configure Tempo traces metrics for details.
