keep 200 users during 30min

Hello,
I would like to generate 200 users and keep this number for 30 min.
I test:
scn.users(360000).ramp(1800)

but I do not get 200 users, but 1000 users.

Thank .

Hi,

What you’ve wrote is that 200 new users will be injected in your scenario every second. What controls their lifespan is your scenario duration.
From your figures, I guess the scenario lasts about 5 seconds, so just decrease the number of users to 72000.

Cheers,

Stéphane
