Question about the ramping arrival rate

Grafana k6 OSS Support

Hi,
I wonder whether the target number is requests per time unit (1s in below example) or number of VUs to use when using the ramping-arrival-rate executor?

Thank you in advance for a clarification.

    stress: {
      executor: "ramping-arrival-rate",
      preAllocatedVUs: 500,
      timeUnit: "1s",
      stages: [
        { duration: "2m", target: 10 }, // below normal load
        { duration: "5m", target: 10 },
        { duration: "2m", target: 20 }, // normal load
        { duration: "5m", target: 20 },
        { duration: "2m", target: 30 }, // around the breaking point
        { duration: "5m", target: 30 },
        { duration: "2m", target: 40 }, // beyond the breaking point
        { duration: "5m", target: 40 },
        { duration: "10m", target: 0 }, // scale down. Recovery stage.
      ],
    },

Hi @Lightlore

The target is in the arrival rate, the iterations. I believe there is a good explanation in Arrival-rate VU allocation, which applies to all arrival rate.

Let me know if you still hae doubts reading that, and we would make a note to improve the docs.

Cheers!
