rampUsers at Runtime


I am trying to either increase or decrease the number of users used in a simulation at Runtime [after the simulation has started]. Is there any way to do that?

For eg,
I would embed a http server along with my simulation. When the simulation starts, it would start with lets say 10 users.
While this simulation is running, I could post to the http server to modify the number of users used in the simulation, lets say the new value is 50.
I want the simulation to rampusers to 50 users, similarly I want to modify the rampusers up or down anytime during the runtime of the Simulation

Pls let know if this is possible in gatling



No, it’s not possible atm, the injection model is static: https://github.com/gatling/gatling/issues/2706

It’s in our list, but I have no idea when we’ll have time to implement it.
