Hi stackers,
When we started Rally we have a just small idea to make some tool that generates load and measures performance. During almost 2 years a lot of changed in Rally, so now it's quite common testing framework that allows to cover various topics like: stress, load, volume, performance, negative, functional testing. Since the begging we have idea of "scenario" centric approach, where scenario method that is called multiple times simultaneously to generate load and duration of it is collected. This is huge limitation that doesn't allow us to easily generate real life load. (e.g. loading simultaneously few components) or HA testing (where we need during the load generation to disable/kill process, reboot or power off physical nodes). To make this possible we should just run multiple scenarios in parallel, but this change will require change in input task format. I made proposal of new Rally task input format in this patch: https://review.openstack.org/#/c/159065/3/specs/new_rally_input_task_format.yaml Please review it. Let's try to resolve all UX issues before starting working on it. P.S. I hope this will be the last big change in Rally input task format.. Best regards, Boris Pavlovic
