# タグ

タグエンドポイントを使用すると、ホストにタグを割り当てることができます。
例: `role:database`。これらのタグは、ホストから送信されるすべてのメトリクスに適用されます。タグを取得して特定のホストに適用するときは、名前でホストを参照します (`yourhost.example.com`)。

タグを担当するインフラストラクチャーのコンポーネントはソースによって識別されます。たとえば、有効なソースには、nagios、hudson、jenkins、users、feed、chef、puppet、git、bitbucket、fabric、capistrano などがあります。

タグの詳細は[タグの概要](https://docs.datadoghq.com/getting_started/tagging.md)をご覧ください。
