## Course wrap-up

**What you learned in Module 1: Metrics Drilldown**

- How Metrics Drilldown organizes data by labels
- The exploration workflow for investigating metrics
- Pattern detection in time series visualizations
- Adding metric findings to dashboards

**What you learned in Module 2: Logs Drilldown**

- How Logs Drilldown organizes data with labels and fields
- The log investigation workflow
- Pattern recognition for errors and anomalies
- Adding log visualizations to dashboards

**What’s next: Level 2 application observability**

This course covered Level 1 infrastructure signals (metrics and logs). The Level 2 course will cover application-level signals that require instrumentation:

- Grafana Traces Drilldown for investigating distributed request flows and latency
- Grafana Profiles Drilldown for continuous profiling data
- Cross-signal correlation workflows connecting all four telemetry types

* * *

In this final module, you’ll:

- See where the Drilldown apps fit in the observability hierarchy
- Remember when to use visual exploration
- Find documentation and next steps

**Estimated time:** 5 minutes
