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 typeDescription
CounterA metric that cumulatively sums added values.
GaugeA metric that stores the min, max and last values added to it.
RateA metric that tracks the percentage of added values that are non-zero.
TrendA metric that calculates statistics on the added values (min, max, average, and percentiles).
