• 'batch' (デフォルト) : BatchSpanProcessor。本番環境のエージェントや 長時間稼働するプロセスに適しています。
• 'simple': SimpleSpanProcessor。スパンごとに HTTP POST を 1 回実行します。 スループットよりも確実な flush が重要となるテストや、短時間で終了する CLI に 適しています。
• SpanProcessor インスタンス: ユーザーが指定するプロセッサです。ライフサイクルの管理は 呼び出し元の責任となり、/agents/otel/v1/traces を送信先とする Weave の OTLP エクスポーターは 使用されません。
