# 在 中記錄 CloudWatch Logs API 和主控台操作 AWS CloudTrail
<a name="logging_cw_api_calls_cwl"></a>

Amazon CloudWatch Logs 已與 整合[AWS CloudTrail](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-user-guide.html)，這項服務可提供使用者、角色或 所採取動作的記錄 AWS 服務。CloudTrail 會將 CloudWatch Logs 的 API 呼叫擷取為事件。擷取的呼叫包括來自 CloudWatch Logs 主控台的呼叫，以及對 CloudWatch Logs API 操作的程式碼呼叫。您可以使用 CloudTrail 所收集的資訊，判斷對 CloudWatch Logs 提出的請求、提出請求的 IP 地址、提出請求的時間，以及其他詳細資訊。

每一筆事件或日誌專案都會包含產生請求者的資訊。身分資訊可協助您判斷下列事項：
+ 該請求是使用根使用者還是使用者憑證提出。
+ 請求是否代表 IAM Identity Center 使用者提出。
+ 提出該請求時，是否使用了特定角色或聯合身分使用者的暫時安全憑證。
+ 該請求是否由另一項 AWS 服務服務提出。

當您建立帳戶 AWS 帳戶 時CloudTrail 會在 中處於作用中狀態，而且您會自動存取 CloudTrail **事件歷史記錄**。CloudTrail **事件歷史記錄**為 AWS 區域中過去 90 天記錄的管理事件，提供可檢視、可搜尋、可下載且不可變的記錄。如需詳細資訊，請參閱「AWS CloudTrail 使用者指南」**中的[使用 CloudTrail 事件歷史記錄](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/view-cloudtrail-events.html)。檢視**事件歷史記錄**不會產生 CloudTrail 費用。

如需 AWS 帳戶 過去 90 天內持續記錄的事件，請建立線索或 [CloudTrail Lake](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-lake.html) 事件資料存放區。

**CloudTrail 追蹤**  
*線索*能讓 CloudTrail 將日誌檔案交付至 Amazon S3 儲存貯體。使用 建立的所有線索 AWS 管理主控台 都是多區域。您可以使用 AWS CLI建立單一或多區域追蹤。建議您建立多區域追蹤，因為您擷取 AWS 區域 帳戶中所有 的活動。如果您建立單一區域追蹤，您只能檢視追蹤 AWS 區域中記錄的事件。如需追蹤的詳細資訊，請參閱《AWS CloudTrail 使用者指南》**中的[為您的 AWS 帳戶建立追蹤](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-create-and-update-a-trail.html)和[為組織建立追蹤](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/creating-trail-organization.html)。  
您可以透過建立追蹤，免費將持續管理事件的一個複本從 CloudTrail 傳遞至您的 Amazon S3 儲存貯體，但這樣做會產生 Amazon S3 儲存費用。如需 CloudTrail 定價的詳細資訊，請參閱 [AWS CloudTrail 定價](https://aws.amazon.com/cloudtrail/pricing/)。如需 Amazon S3 定價的相關資訊，請參閱 [Amazon S3 定價](https://aws.amazon.com/s3/pricing/)。

**CloudTrail Lake 事件資料存放區**  
*CloudTrail Lake* 讓您能夠對事件執行 SQL 型查詢。CloudTrail Lake 會將分列式 JSON 格式的現有事件轉換為 [Apache ORC](https://orc.apache.org/) 格式。ORC 是一種單欄式儲存格式，針對快速擷取資料進行了最佳化。系統會將事件彙總到*事件資料存放區*中，事件資料存放區是事件的不可變集合，其依據為您透過套用[進階事件選取器](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-lake-concepts.html#adv-event-selectors)選取的條件。套用於事件資料存放區的選取器控制哪些事件持續存在並可供您查詢。如需 CloudTrail Lake 的詳細資訊，請參閱*AWS CloudTrail 《 使用者指南*》中的[使用 AWS CloudTrail Lake](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-lake.html)。  
CloudTrail Lake 事件資料存放區和查詢會產生費用。建立事件資料存放區時，您可以選擇要用於事件資料存放區的[定價選項](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-lake-manage-costs.html#cloudtrail-lake-manage-costs-pricing-option)。此定價選項將決定擷取和儲存事件的成本，以及事件資料存放區的預設和最長保留期。如需 CloudTrail 定價的詳細資訊，請參閱 [AWS CloudTrail 定價](https://aws.amazon.com/cloudtrail/pricing/)。

每一筆事件或日誌專案都會包含產生請求者的資訊。身分資訊可協助您判斷下列事項：
+ 該請求是否使用根或 IAM 使用者憑證提出。
+ 提出該請求時，是否使用了特定角色或聯合身分使用者的暫時安全憑證。
+ 請求是否由其他 AWS 服務提出。

如需詳細資訊，請參閱 [CloudTrail userIdentity 元素](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-event-reference-user-identity.html)。

## CloudTrail 中的查詢產生資訊
<a name="cwl_query-generation-cloudtrail"></a>

同時支援針對查詢產生器主控台事件的 CloudTrail 記錄。CloudWatch Logs Insights 和 CloudWatch Metric Insights 目前支援查詢產生器。在這些 CloudTrail 事件中，`eventSource` 是 `monitoring.amazonaws.com`。

下列範例顯示 CloudTrail 日誌項目，示範 CloudWatch Logs Insights 中的 **GenerateQuery** 動作。

## 了解 日誌檔案項目
<a name="understanding_cw_log_file_entries_cwl"></a>

 追蹤是一種組態，可讓事件以日誌檔案的形式交付至您指定的 Amazon S3 儲存貯體。CloudTrail 日誌檔案包含一或多個日誌專案。一個事件為任何來源提出的單一請求，並包含請求動作、請求的日期和時間、請求參數等資訊。CloudTrail 日誌檔並非依公有 API 呼叫的堆疊追蹤排序，因此不會以任何特定順序出現。

以下日誌檔案項目顯示使用者呼叫 CloudWatch Logs **CreateExportTask** 動作。
