# Understand root cause analysis using the knowledge graph

Frontend Observability integrates with the [knowledge graph](/docs/grafana-cloud/knowledge-graph/) to accelerate troubleshooting and reduce mean time to repair. This integration extends Frontend Observability with advanced capabilities to understand how frontend issues relate to broader system problems, helping you quickly identify whether frontend errors stem from database connectivity issues, service degradations, or other infrastructure problems.

The integration leverages [RCA workbench](/docs/grafana-cloud/knowledge-graph/troubleshoot-infra-apps/workbench/) to broaden your perspective into the system. You can understand which components are related, such as services, tools, and events, enabling you to take troubleshooting deeper by understanding the root cause of issues. For example, your application could be returning errors because backend services can’t connect to a database.

The knowledge graph also provides health metrics that offer hints that the system has issues that might require more attention.

## Access RCA workbench

Within Frontend Observability, access RCA workbench to continue [root cause analysis](/docs/grafana-cloud/knowledge-graph/troubleshoot-infra-apps/workbench/#use-the-timeline-to-perform-root-cause-analysis). From any Frontend Observability dashboard where the **Insights** button appears, click it and then click **Open in RCA workbench** to continue your investigation into issues.

For example, you can use RCA workbench to discover which service downstream might be impacting the frontend performance.
