Each entry in the report represents a metric `metric_name` along with its value `metric_value` at time `timestamp`. If there's an error, then the `error` along with the `error_code` fields will be populated.


## CSV options

k6 provides a few options to help you configure your CSV output:


| option | Configures | Possible values | Default | Env. variable |
|-------------------------------|--------------------------------------------------|---------------------------------------------------------------------------|------------|------------------------|
| `saveInterval` | The time intervals at which k6 writes to the CSV | Either a string with time units(`"1m45s"`), or a number of milliseconds | `"1s"` | `K6_CSV_SAVE_INTERVAL` |
| `timeFormat` | The timestamp format | unix, [rfc3339](https://datatracker.ietf.org/doc/html/rfc3339) | unix | `K6_CSV_TIME_FORMAT` |
| `fileName` | The file name and path where output is saved | N/A | `file.csv` | `K6_CSV_FILENAME` |
