Collector for Linux のデフォルト設定 🔗

The Splunk Distribution of the OpenTelemetry Collector has the following components and services:

  • レシーバー: Collector にデータを取り込む方法を決定します。

  • プロセッサー ：エクスポートする前にデータに対してどのような処理を行うかを設定します。例えば、フィルターリングなど。

  • エクスポーター: データの送信先を設定します。1つまたは複数のバックエンドまたは送信先を指定できます。

  • 拡張 ： Collector の機能を拡張します。

  • サービス。これは2つの要素で構成されています：

    • 設定した 拡張機能 のリスト。

    • パイプライン: データが受信から加工や修正を経て、最終的にエクスポーターを経由して出るまでのパス。

詳細は Collector コンポーネント を参照してください。

Collector の設定は YAML ファイル に保存され、さまざまなコンポーネントとサービスの動作を指定します。以下のセクションで、デフォルト設定の要素とパイプラインの概要を参照してください。

Collectorの設定方法については、Tutorial: Configure the Splunk Distribution of OpenTelemetry Collector on a Linux host を参照してください。

デフォルトのパイプライン 🔗

デフォルトでは、取り込まれたデータはこれらのパイプラインに従います。

ログのデフォルト・パイプライン 🔗

以下の図は、デフォルトのログ・パイプラインを示しています：

The logs/memory_limiter processor sends logs to the batch processor, and the batch processor sends logs to the resource detection processor.
