Hi,

I have a problem when I execute a simulation : final reports are empty.  
I have no errors when reports are generated, I’ve try to increase the Xms and Xmx parameter, but it’s change nothing.  
My simulation is on 600 users with a ramp at 300, with 152 request.

Anyone have an idea ?

Regards,

Hi there,

Could you post your scenario, please (a gist is the best way)?  
You probably wrote your scenario in a way that it’s empty (it doesn’t send any request).

Cheers,

Stephane

Hi,

Please find here my scenario.  
I’ve specify that I have executed this scenario with less user (10) and reports are well produced.

I can’t see anything wrong with your scenario…  
Could you provide the following information, please:

- Gatling version
- OS

Could you also clarify what you mean by empty? Do you get a “There were no requests sent during the simulation, reports won’t be generated” warn log when you try to generate the charts?  
What’s you simulation.log file size? Could you post it?

Cheers,

Steph
