# 範例：WorkSpaces 應用程式日誌檔案項目
<a name="understanding-service-name-entries"></a>

 追蹤是一種組態，能讓事件以日誌檔案的形式交付到您指定的 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。

以下範例顯示展示 `AssociateFleet` 事件的 CloudTrail 日誌項目。

```

  "userIdentity": {
    "type": "AssumedRole",
    "principalId": "AIDACKCEVSQ6C2EXAMPLE:janeroe",
