How to simulate ramp-up with Locust?

Question

As I know Ramp-up function has been removed from locust. Just wondering if the hatching process was the same as or similar to ramp-up? Or is there anyway to simulate the situation?

Answer 1

Not sure about what ramp up function you are talking about. There are plenty of options for controlling ramp-up in locust, including the new step-load function:

  --step-load           Enable Step Load mode to monitor how performance
                        metrics varies when user load increases. Requires
                        --step-clients and --step-time to be specified.
  --step-clients STEP_CLIENTS
                        Client count to increase by step in Step Load mode.
                        Only used together with --step-load
  --step-time STEP_TIME
                        Step duration in Step Load mode, e.g. (300s, 20m, 3h,
                        1h30m, etc.). Only used together with --step-load

Just found a workaround by Taurus to schedule the load.
