## Prerequisites

To complete this course, you’ll need:

- Grafana Cloud or self-managed Grafana (v11.6+) ([sign up for Cloud free](/signup/cloud/connect-account))
- Access to Drilldown apps in your Grafana instance
- At least one infrastructure telemetry signal accessible in Grafana (metrics or logs)

## Data access options

Your telemetry data can be accessible via data sources or stored in Grafana Cloud’s built-in databases:

| Data type   | Access via data source | Or store in Cloud     |
|-------------|------------------------|-----------------------|
| **Metrics** | Prometheus data source | Grafana Cloud Metrics |
| **Logs**    | Loki data source       | Grafana Cloud Logs    |

## What you’ll use

During the hands-on learning paths, you’ll work with the Drilldown apps in Grafana. Access them from the Grafana main menu by selecting Drilldown, then choosing the specific app (Metrics or Logs). They work with your existing data automatically.

## No query language knowledge required

This course is designed for visual exploration. You don’t need to know PromQL or LogQL.
