Distributed tracing in Grafana Cloud k6

You can now use the Grafana Cloud Traces integration with Grafana Cloud k6 to quickly debug failed performance tests and proactively improve application reliability.

Distributed tracing in Grafana Cloud k6 only requires two things:

An application instrumented for tracing with Grafana Cloud Traces.
Adding a few lines of code to your existing k6 scripts.

The integration works by having k6 inject tracing metadata into the requests it sends to your backend services when you run a test. The tracing data is then correlated with k6 test run data, so you can understand how your services and operations behaved during the whole test run. The collected tracing data is aggregated to generate real-time metrics—such as frequency of calls, error rates, and percentile latencies—that can help you narrow your search space and quickly spot anomalies.
