[2] Rally をインストールします。
# Wallaby, EPEL, PowerTools からインストール

[root@dlp ~(keystone)]#
dnf --enablerepo=centos-openstack-wallaby,powertools,epel -y install openstack-rally openstack-rally-plugins python3-fixtures
[3] Rally の基本設定です。
[root@dlp ~(keystone)]#
vi /etc/rally/rally.conf
# 33行目 : ログファイル名を追記

log_file = rally.log
# 38行目 : ログ格納ディレクトリ名を追記

log_dir = /var/log/rally
# 203行目 : MariaDB 接続情報を追記

connection = mysql+pymysql://rally:password@10.0.0.30/rally
[root@dlp ~(keystone)]#
mkdir /var/log/rally

[root@dlp ~(keystone)]#
rally db create

Creating database: mysql+pymysql://rally:password@10.0.0.30/rally
Database created successfully
[4] Rally がベンチマークタスクを実行できるよう認証情報を登録しておきます。
URL や ユーザー情報等は自身の環境に置き換えてください。
[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)]#
source ~/.rally/openrc

[root@dlp ~(keystone)]#
rally deployment show my-cloud

[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

[root@dlp ~(keystone)]#
vi boot-and-delete.json
{
  "NovaServers.boot_and_delete_server": [
    {
      "args": {
        "flavor": {
          "name": "m1.small"
        },
        "image": {
          "name": "CentOS-Stream-8"
        },
        "force_delete": false
      },
      "runner": {
        "type": "constant",
        "times": 10,
        "concurrency": 2
      },
      "context": {}
    }
  ]
}

# ベンチマークタスクを開始

[root@dlp ~(keystone)]#
rally task start boot-and-delete.json

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

Task is:
{
  "NovaServers.boot_and_delete_server": [
    {
      "args": {
        "flavor": {
          "name": "m1.small"
        },
        "image": {
          "name": "CentOS-Stream-8"
        },
        "force_delete": false
      },
      "runner": {
        "type": "constant",
        "times": 10,
        "concurrency": 2
      },
      "context": {}
    }
  ]
}

Task syntax is correct :)
