# Use signals together

The real power of telemetry comes from using signals together. Correlate metrics, logs, traces, and profiles to troubleshoot issues faster.

## Before you begin

To get the most from signal correlation, you need:

- Data ingestion from at least two telemetry signals (metrics, logs, traces, or profiles)
- Consistent labels and attributes configured across your signals (such as `service`, `environment`, `namespace`)
- Basic familiarity with the Grafana Drilldown apps or Grafana Explore

If you haven’t set up correlation yet, refer to [Configure signal correlation](/docs/grafana-cloud/telemetry-signals/use-signals-together/setup-correlations/).

## Learning path

1. Understand the concepts: [Observability concepts](/docs/grafana-cloud/telemetry-signals/use-signals-together/key-concepts/) and [Why correlation matters](/docs/grafana-cloud/telemetry-signals/use-signals-together/why-correlation-matters/)
2. Set up correlation: [Configure signal correlation](/docs/grafana-cloud/telemetry-signals/use-signals-together/setup-correlations/)
3. Master navigation: [Navigate between signals](/docs/grafana-cloud/telemetry-signals/use-signals-together/navigation-between-signals/)
4. Solve problems: [Troubleshoot signal correlation](/docs/grafana-cloud/telemetry-signals/use-signals-together/troubleshooting/)
