Printing the current step

Gatling (Open-Source)
1

Hello,

I have a Gatling scenario defines a couple of steps like this:

constantUsersPerSec(2).during(200.seconds),
nothingFor(10.seconds),
constantUsersPerSec(0.25).during(25.seconds),
nothingFor(10.seconds),
constantUsersPerSec(0.5).during(50.seconds),
nothingFor(10.seconds),
constantUsersPerSec(1).during(200.seconds),
nothingFor(10.seconds),
constantUsersPerSec(2).during(200.seconds),
nothingFor(10.seconds),
constantUsersPerSec(4).during(200.seconds),
nothingFor(10.seconds),
constantUsersPerSec(8).during(200.seconds),
nothingFor(10.seconds),
constantUsersPerSec(16).during(200.seconds)

This scenario takes about 25 minutes to complete and the log only sends the number and percentage of requests completed.

I would like to see in the log what the current step is.

Is there a way to inject a print statement into my list of steps?

I’m looking for something along the lines of this:

constantUsersPerSec(2).during(200.seconds),
println(“Step 1 completed”),

nothingFor(10.seconds),
constantUsersPerSec(0.25).during(25.seconds),
println(“Step 2 completed”),
nothingFor(10.seconds),
constantUsersPerSec(0.5).during(50.seconds),
println(“Step 3 completed”),

How can I achieve this?

Thanks
Leonard

That’s not possible.

Then, what would “completed” mean? Please understand injection engine doesn’t wait for users that were started in a step to terminate in order to proceed with the next step. It proceed has soon as it has finished starting the users.
