# 資料庫活動串流的稽核日誌內容和範例
受監控的事件會以 JSON 字串的形式在資料庫活動串流中顯示。此結構包含 JSON 物件，內含的 `DatabaseActivityMonitoringRecord` 會依序包含活動事件的 `databaseActivityEventList` 陣列。
**注意**
對於資料庫活動串流，`paramList` JSON 陣列不包含休眠應用程式的 null 值。

## 活動串流的稽核記錄範例
以下是活動事件記錄的範例解密 JSON 稽核日誌。
**Example a CONNECT SQL 陳述式的活動事件記錄**
以下活動事件記錄顯示 JDBC 精簡用戶端 (`clientApplication`) 使用 `CONNECT` SQL 陳述式 (`command`) 登入您的 Oracle 資料庫。

## DatabaseActivityMonitoringRecords JSON 物件
資料庫活動事件記錄位於 JSON 物件中，其中包含下列資訊。
****
| JSON 欄位 | 資料類型 | 描述 |
| --- | --- | --- |
| `type` | string | JSON 記錄類型。值為 `DatabaseActivityMonitoringRecords`。 |
| version | string | 資料庫活動監控記錄的版本。Oracle 資料庫使用 1.3 版，SQL Server 則使用 1.4 版。這些引擎版本引入 engineNativeAuditFields JSON 物件。 |
| [databaseActivityEvents](#DBActivityStreams.AuditLog.databaseActivityEvents) | string | 包含活動事件的 JSON 物件。 |
| 金鑰 | string | 您用來解密 [databaseActivityEventList JSON 陣列](DBActivityStreams.AuditLog.databaseActivityEventList.md) 的加密金鑰 |
## databaseActivityEvents JSON 物件
`databaseActivityEvents` JSON 物件包含以下資訊。
### JSON 記錄中的最上層欄位
稽核記錄檔中的每個事件都會包裝在 JSON 格式的記錄中。此記錄包含下列欄位。
**type**
此欄位永遠具有值 `DatabaseActivityMonitoringRecords`。
**version**
此欄位代表資料庫活動串流資料通訊協定或合約的版本。其會定義哪些欄位可用。
**databaseActivityEvents**
代表一或多個活動事件的加密字串。它被表示為一個 base64 位元組陣列。在您解密字串時，結果會是 JSON 格式的記錄，其中包含欄位，如本節範例所示。
**金鑰**
用來加密 `databaseActivityEvents` 字串的加密資料金鑰。這與您啟動資料庫活動串流時 AWS KMS key 提供的相同。
下列範例顯示此記錄的格式。
```
{
"type":"DatabaseActivityMonitoringRecords",
"version":"1.3",
"databaseActivityEvents":"encrypted audit records",
"key":"encrypted key"
}
```
```
"type":"DatabaseActivityMonitoringRecords",
"version":"1.4",
"databaseActivityEvents":"encrypted audit records",
"key":"encrypted key"
```
採取下列步驟來解密 `databaseActivityEvents` 欄位的內容：
1. 使用您在啟動資料庫活動串流時提供的 KMS 金鑰，解密 `key` JSON 欄位中的值。這麼做會以純文字傳回資料加密金鑰。
1. Base64 解碼 `databaseActivityEvents` JSON 欄位中的值，以取得稽核承載的二進位格式的加密文字。
1. 使用您在第一個步驟中解碼的資料加密金鑰來解密二進位密文。
1. 解壓縮已解密的承載。
+ 加密的承載在 `databaseActivityEvents` 欄位。
+ 該 `databaseActivityEventList` 欄位包含稽核記錄的陣列。陣列中的 `type` 欄位可以是 `record` 或 `heartbeat`。
稽核日誌活動事件記錄是包含以下資訊的 JSON 物件。
****
| JSON 欄位 | 資料類型 | 描述 |
| --- | --- | --- |
| `type` | string | JSON 記錄類型。值為 `DatabaseActivityMonitoringRecord`。 |
| instanceId | string | 資料庫執行個體資源識別符。它對應於資料庫執行個體屬性 DbiResourceId。 |
| [databaseActivityEventList JSON 陣列](DBActivityStreams.AuditLog.databaseActivityEventList.md) | string | 活動稽核記錄或活動訊號訊息的陣列。 |
