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)]#
source ~/.rally/openrc

[5] Rally の利用方法です。
なお、下例で定義しているベンチマークシナリオのその他サンプルは下記サイトを参照ください。
⇒ https://github.com/openstack/rally/blob/master/samples/tasks/scenarios/
# ベンチマークのシナリオを定義する

# 例として インスタンスの作成/起動～削除までを行うシンプルなシナリオを定義

# [flavor] は登録済みの flavor 名を指定

# [image] は登録済みの image 名を指定

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

Task is:
{
    "NovaServers.boot_and_delete_server": [
        {
            "args": {
                "flavor": {
                    "name": "m1.small"
                },
                "image": {
                    "name": "CentOS7"
                },
                "force_delete": false
            },
            "runner": {
                "type": "constant",
                "times": 10,

            },
            "context": {}
        }

}

Task syntax is correct :)
