概要
Datadog-Ceph インテグレーションを有効にすると、以下のことができます。
- ストレージプール全体のディスク使用状況を追跡できます。
- 問題が発生した場合にサービスチェックを受信できます。
- I/O パフォーマンスメトリクスを監視できます。
セットアップ
インストール
Ceph チェックは Datadog Agent パッケージに含まれています。Ceph サーバーに追加でインストールする必要はありません。
構成
Agent のコンフィギュレーションディレクトリのルートにある conf.d/ フォルダーの ceph.d/conf.yaml ファイルを編集します。
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の詳細については、サンプル ceph.d/conf.yaml を参照してください。
init_config:
instances:
- ceph_cmd: /path/to/your/ceph # default is /usr/bin/ceph
use_sudo: true # ご利用のノードで ceph バイナリが sudo を必要とする場合のみ
use_sudo を有効にした場合は、sudoers ファイルに以下のような行を追加します。
dd-agent ALL=(ALL) NOPASSWD:/path/to/your/ceph
ログ収集
Agent バージョン 6.0 以降で利用可能
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 ファイルでこれを有効にします。
次に、下部にある logs 行のコメントを解除して、ceph.d/conf.yaml を編集します。ログの path を Ceph ログファイルの正しいパスで更新してください。
logs:
- type: file
path: /var/log/ceph/*.log
source: ceph
service: "<APPLICATION_NAME>"
Agent を再起動します。
検証
Agent の status サブコマンドを実行し、Checks セクションで ceph を探します。
