With --out flag, k6 allows to write not just summary, but constantly changing metrics. Besides JSON and CSV, there is a number of other targets, see
https://k6.io/docs/results-output/real-time/
We need to check whether some of these defaults work with VictoriaMetrics.

If it is not possible, we write a custom output extension:
https://k6.io/docs/extensions/get-started/create/output-extensions/
