k6/metrics
The metrics module provides functionality to create custom metrics of various types. All metrics (both the built-in metrics and the custom ones) have a type.
You can optionally tag all values added to a custom metric, which can be useful when analysing the test results.
| Metric type | Description |
|---|---|
| Counter | A metric that cumulatively sums added values. |
| Gauge | A metric that stores the min, max and last values added to it. |
| Rate | A metric that tracks the percentage of added values that are non-zero. |
| Trend | A metric that calculates statistics on the added values (min, max, average, and percentiles). |
