Aggregation methods for metric queries
The following tables include the aggregation methods for the k6 metrics query type. An aggregation method is a function that returns a numerical value when applied to a specific time span of a metric.
Counter methods
| Method | Previous method | Description |
|---|---|---|
| Increase | Sum | Counter increase in time period |
| Rate | RPS | Average rate of counter increase per second |
| Cum. Sum | Cum. Sum, Count | Counter total value up to the end of time period |
| Cum. Rate | Cum. Rate, Cum. RPS | Average rate from the start of test run to the end of time period |
Gauge methods
| Method | Previous method | Description |
|---|---|---|
| Sum (Last) | Sum (Last) | |
| Max (Last) | Max (Last) |
Rate methods
| Method | Previous method. | Description |
|---|---|---|
| Non-zero fraction | Rate | Fraction of reported non-zero values. For example: successful checks |
| Increase | Count | Count increase over time period |
| Cum. Sum | Cum. Count | Total count value up to the end of time period |
| Rate | RPS | Total count increase per second |
| Increase (non-zero) | Passes, Non-Zero Count | Non-zero observations count increase over time period |
| Cum. Sum (non-zero) | Cum. Non-Zero Count | Non-zero observations count value up to the end of time period |
| Rate (non-zero) | Non-Zero RPS | Total count increase per second |
| Increase (zero) | Failures | Zero-observations counter increase in the time period |
Trend methods
| Method | Previous method | Description |
|---|---|---|
| Max | Max | Maximum observed value |
| Min | Min | Minimum observed value |
| Avg | Average | Average of values |
| Std. Dev. | Std. Dev. | Standard deviation |
| Count increase | Count | Count of observations over time period |
| Cum. Count | Cum. Count | Total count of observations stored in Trend metric |
| Cum. Min | Cum. Min | Cumulative minimum observed value |
| Cum. Max | Cum. Max | Cumulative maximum observed value |
| Cum. Avg | Cum. Avg., Cum. Mean | Cumulative average of values |
| Cum. Std. Dev. | Cum. Std. Dev. | Cumulative standard deviation |
| Median | Median | |
| 75th percentile | 75th Percentile | |
| 90th percentile | 90th Percentile | |
| 95th percentile | 95th Percentile | |
| 99th percentile | 99th Percentile | |
| Rate | Histogram count rate | Average rate of counter increase per second |
