How to define step load on gatling

I'm a Performance QC engineer, so far i used Visual Studio Ultimate to run load test bug now I'm going to change to gatling. So I'm a newbie on gatling and scala.

I'm defining the simulation with step-load scenario here:

Meaning: start with 5 users > after 10 seconds increase 5 users: repeat until maximum 100 user and run the test in 10 minutes.

I tried some code and other injects but the result is not as expected: 

splitUsers(100)
into(rampUsers(5)
over(10 seconds))
separatedBy(10 minutes)

Could you please help me to simulate the step load on gatling?

define the User injection part in setUp something like this

setUp(
    scn.inject(
      atOnceUsers(5),            //Initial: 5 user
      nothingFor(10 seconds),    //A pause to uniform the step load   
      splitUsers(100) into atOnceUsers(5) separatedBy(10 seconds) //max user,split time,number of user
    ).protocols(httpConf))

the duration you can define just by using during function over scenario. Hope it helps

Can you be more specific about the result not being as expected?

According to the documentation your situation should be:

splitUsers(100) into(rampUsers(5) over(10 seconds)) separatedBy atOnceUsers(5)

If test duration is the target then have a look at Throttling in the Gatling documentation.
