Distributed Tracing in Grafana Cloud k6, now generally available, bridges the visibility gap between performance testing and system tracing, allowing engineering teams to troubleshoot failed performance tests more efficiently. By integrating Grafana Cloud Traces with Grafana Cloud k6, users can correlate performance test results with server-side tracing data, reducing the mean time to recovery (MTTR) and improving application reliability. This integration enables automatic injection of tracing metadata into backend service requests, supporting major propagators like W3C (OpenTelemetry) and Jaeger. The collected data generates real-time metrics and provides a summary view of all spans generated during testing. This allows users to identify root causes of issues, such as in a hypothetical scenario where a locking issue in MySQL caused significant latency. Users can explore specific traces to diagnose problems, making Distributed Tracing in Grafana Cloud k6 a valuable tool for proactively addressing potential customer and revenue impacts. The integration is available for all Grafana Cloud users, including those on the free tier, and setup involves sending service tracing data to Grafana Cloud Traces and enabling the tracing feature in Grafana Cloud k6 tests.
