Need help to get rally test suite

Hello Experts, Need some help on rally. I have installed Openstack rally on centos. Now I need to run some benchmarking test suite. I need to know is there any pre-existing test suite which covers majority of test cases for Openstack control plane. So that I can just run that test suite. I remember earlier we use to get the samples under rally/samples/tasks/scenarios for each component but now I am not seeing it but I am seeing some dummy files. So from where I can get those samples json/yaml files which is required to run the rally tests. Awaiting for your response. Thanks in Advance Regards, Ankit Goel
