[4] Add environment variables for Openstack to Rally to run Rally BenchiMarking Tasks.
The [rally] command On Ussuri version, many Warnings by Python are shown, but it works normally for the time being.
[root@dlp ~(keystone)]#
rally deployment create --fromenv --name=my_cloud

HINTS:

* To use standard OpenStack clients, set up your env by running:
        source ~/.rally/openrc
  OpenStack clients are now configured, e.g run:
        openstack image list

[root@dlp ~(keystone)]#

[5] How to use Rally.
For a sample scenario in follwoing tutorial, there are many other samples on the site below, refer to them.
⇒ https://github.com/openstack/rally/blob/master/samples/tasks/scenarios/
# define Benchimarking scenario

# for example, define a simple scenario to create and delete a compute instance

# for [flavor], specify your own registered flavor name

# for [image], specify your own registered image name

[root@dlp ~(keystone)]#
vi boot-and-delete.json
{
    "NovaServers.boot_and_delete_server": [
        {

                    "name": "m1.small"
                },
                "image": {
                    "name": "CentOS8"
                },

    ]
}

# start BenchiMarking Tasks

[root@dlp ~(keystone)]#

Preparing input task
--------------------------------------------------------------------------------

Task is:
{
    "NovaServers.boot_and_delete_server": [
        {
            "args": {
                "flavor": {
                    "name": "m1.small"
                },
                "image": {
                    "name": "CentOS7"
                },
                "force_delete": false
            },

            },
            "context": {}
        }
    ]
}

Task syntax is correct :)
