注: このインテグレーションは、OpenStack v13+ (コンテナ化された OpenStack) にのみ適用されます。OpenStack v12 以下 (コンテナ化されていない OpenStack) からメトリクスを収集する場合は、OpenStack インテグレーションを使用してください。
このチェックは、コントローラーノードから OpenStack を監視します。
OpenStack Controller チェックは Datadog Agent パッケージに含まれているため、サーバーに追加でインストールする必要はありません。
OpenStack Controller インテグレーションは、すべてのコンピュートノードおよびそれを実行しているサーバーから情報を収集するように設計されています。また、単一の Agent から実行して OpenStack 環境を監視します。このインテグレーションは、コントローラーノード、または Keystone および Nova エンドポイントにアクセスできる隣接サーバーでデプロイできます。
openstack_controller.d/conf.yaml
ファイルで使用される datadog
ユーザーを作成します。このユーザーには、環境全体に対する管理読み取り専用アクセス許可が必要です。これにより、単一のノードから実行して、すべてのノードとサーバーに関する高レベルなシステム情報を読み取ることができます。
OpenStack Controller のパフォーマンスデータの収集を開始するには、Agent の構成ディレクトリのルートにある conf.d/
フォルダーの openstack_controller.d/conf.yaml
ファイルを編集します。使用可能なすべての構成オプションの詳細については、サンプル openstack_controller.d/conf.yaml を参照してください。
init_config:
instances:
## @param name - string - required
## Unique identifier for this instance.
#
- name: "<INSTANCE_NAME>"
## @param user - object - required
## Password authentication is the only auth method supported
## User expects username, password, and user domain id
## `user` should resolve to a structure like
## {'password': '<PASSWORD>', 'name': '<USER_NAME>', 'domain': {'id': '<DOMAIN_ID>'}}
## The check uses the Unscoped token method to collect information about
## all available projects to the user.
#
user:
password: "<PASSWORD>"
name: "<USER_NAME>"
domain:
id: "<DOMAIN_ID>"
Datadog Agent で、ログの収集はデフォルトで無効になっています。以下のように、datadog.yaml
でこれを有効にできます。
logs_enabled: true
Openstack ログの収集を開始するには、次のコンフィギュレーションブロックを openstack_controller.d/conf.yaml
ファイルに追加します。
logs:
- type: file
path: "<LOG_FILE_PATH>"
source: openstack
path
パラメーターの値を変更し、環境に合わせて構成します。使用可能なすべてのコンフィギュレーションオプションについては、サンプル openstack_controller.d/conf.yaml を参照してください。
