k6 emits metrics with timestamps at every point of the test. You can output the metric results as either aggregated statistics or individual data points.
- For a top-level test overview, use the end-of-test summary.
- For granular output of all metrics (with timestamps), you stream metrics in real time.
If you stream your metrics, you can either write them to a file, like JSON, or stream them to a service, like InfluxDB.
