Enter the number of virtual users you want to run your test. Since this is your first flood, we'd recommend starting with a small number as a proof-of-concept.
For more information about the maximum number of users that you can run on each node, go to Users.
Setting the duration for your flood
In Duration, you can choose how long you want to run your test. Move the slider or enter the duration in minutes (we recommend up to 15 minutes for now).
For more information about this parameter, you can go to Duration.
Setting a ramp up period in minutes for your users
Ramp up is the amount of time it takes for your test to go from 0 users to the number of users that you set. Since we're not running many users now, it's safe to leave it at 0 minutes.
For more information about ramp up, check out Ramp up.
Summary and Launch
Cost estimates are shown before launching a test
You'll see a summary of the settings you've selected, including an estimate of the VUH the test will consume and how much it will cost. Note that they are estimates because the final cost may vary. For instance, if you're still on the free tier, you won't be charged.
