使用 Aria Operations for Logs 查看統一安全性記錄

使用 Aria Operations for Logs，您可以隨時檢視 NSX 環境的安全性流量記錄。

以下安全性功能支援流量記錄：

TLS 檢查
閘道 IDPS
URL 篩選

統一安全性記錄

所有安全性類別都以統一安全性記錄格式產生統一安全性流量記錄，並儲存在節點上的單一記錄檔中。此單一記錄將匯出至設定給 Aria Operations for Logs 的 Syslog 伺服器。然後，Aria Operations for Logs 會處理記錄來提供進一步的記錄管理、分析，並使用 NSX 內容套件來顯示記錄。

在 Aria Operations for Logs 上顯示記錄

NSX 內容套件中的 [NSX - 統一安全性流量記錄] 儀表板會顯示一些圖表 Widget，以視覺化方式呈現安全性流量記錄。

Aria Operations for Logs 內容套件是一個外掛程式。其中包含與特定一個產品或一組記錄相關的儀表板、擷取的欄位、儲存的查詢及警示。

NSX 內容套件已在 Aria Operations for Logs 市集上推出。

如需有關 Aria Operations for Logs 及如何從內容套件市集安裝內容套件的詳細資訊，請參閱 Aria Operations for Logs 說明文件中的〈從內容套件市集安裝內容套件〉一章。

前 N 個和過去 X 小時

您還可以使用互動式分析和內容套件，查詢 Aria Operations for Logs 中的事件，以獲得過去 X 小時的前 N 個資訊。

遠端記錄伺服器

若要將記錄傳送至遠端記錄伺服器，必須分別在每個節點上為 NSX 應用裝置和 Hypervisor 設定遠端記錄。

備註：若要將記錄傳送至 Syslog 伺服器，您必須確保對 NSX Manager 上的特定規則啟用記錄。

如需詳細資訊，請參閱設定遠端記錄。

如果遠端記錄伺服器不接收記錄，請參閱對 Syslog 問題進行疑難排解。

統一安全性記錄格式

在 Edge 節點上，統一安全性流量記錄都儲存在 /var/log/syslog 中。您可以用 root 使用者身分登入，並使用 grep 命令搜尋此檔案以找出統一記錄。例如：

cat /var/log/syslog | grep 'unified-logs'
