CSV
You can output granular data points in CSV format.
To do so, use k6 run with the --out flag.
Pass the path for your CSV file as the flag argument:
k6 run --out csv=test_results.csv script.jsYou can also get the results gzipped, like this:
k6 run --out csv=test_results.gz script.jsTo inspect the output in real time, you can use a command like tail -f on the file you save:
tail -f test_results.csvCSV format
The CSV result file will look something like this:
metric_name,timestamp,metric_value,check,error,error_code,group,method,name,proto,scenario,status,subproto,tls_version,url,extra_tags
