您可以設定 NSX 應用裝置、NSX Edge 及 Hypervisor 以傳送記錄訊息至遠端記錄伺服器。

NSX Manager、NSX Edge 和 Hypervisor 支援遠端記錄。您必須在每個節點上個別設定遠端記錄。

如果針對 NSX 分散式惡意程式碼防護服務啟用了主機叢集，則可以登入每個主機上的 NSX 惡意軟體防護服務虛擬機器 (SVM)，並在 SVM 上設定遠端記錄。從 NSX 4.1.2 開始支援此功能。如需詳細資訊，請參閱在 NSX 惡意軟體防護服務虛擬機器上設定遠端記錄。

對於通訊協定參數，選項包括 UDP、TCP、LI 以及安全通訊協定 TLS 和 LI-TLS。請注意，LI 和 LI-TLS 是 Aria Operations for Logs 通訊協定。Aria Operations for Logs 記錄伺服器支援所有通訊協定。僅當記錄伺服器為 Aria Operations for Logs 時，才可使用通訊協定 LI 和 LI-TLS。使用 LI 或 LI-TLS 的好處是它們能夠最佳化網路使用量。如果記錄伺服器為 Aria Operations for Logs，建議使用 LI 或 LI-TLS。如果無法使用 LI，則 TCP 的優勢是更加可靠，而 UDP 的優勢是需要較少的系統和網路額外負荷。

必要條件

  • 請自行熟悉 CLI 命令 set logging-server。如需詳細資訊，請參閱《NSX 命令列介面參考》。
  • 如果指定安全通訊協定 TLS 或 LI-TLS，則伺服器和用戶端憑證必須儲存在每個 NSX 應用裝置上的 /image/vmware/nsx/file-store 中。請注意，只有在使用 NSX CLI 來設定匯出工具時，才需要檔案存放區中的憑證。如果您使用 API，則不需要使用檔案存放區。完成 Syslog 匯出工具設定後，您必須從這個位置刪除所有的憑證和金鑰，以免產生潛在的安全性漏洞。
  • 若要設定記錄伺服器的安全連線，請確認已為伺服器設定 CA 簽署的憑證。例如，如果您使用 Aria Operations for Logs 伺服器 vrli.prome.local 作為記錄伺服器，則可以從用戶端執行下列命令，以查看伺服器上的憑證鏈結：
    echo -n | openssl s_client -connect vrli.prome.local:443  | sed -ne '/^Certificate chain/,/^---/p'

    例如：

    root@caserver:~# echo -n | openssl s_client -connect vrli.prome.local:443  | sed -ne '/^Certificate chain/,/^---/p'
depth=2 C = US, L = California, O = GS, CN = Orange Root Certification Authority
verify error:num=19:self signed certificate in certificate chain

程序

  1. 若要在 NSX 應用裝置或 NSX Edge 上設定遠端記錄，請執行以下操作：
    1. 執行下列命令來設定記錄伺服器和要傳送至記錄伺服器的訊息類型。您可以使用逗號分隔且無空格的清單來指定多個設施或訊息識別碼。 
      set logging-server <hostname-or-ip-address[:port]> proto <proto> level <level> [facility <facility>] [messageid <messageid>] [serverca <filename>] [clientca <filename>] [certificate <filename>] [key <filename>] [structured-data <structured-data>]
      您可以執行此命令多次，以新增多個組態。例如： 
      set logging-server 192.168.110.60 proto udp level info facility local6 messageid SYSTEM,FABRIC
      set logging-server 192.168.110.60 proto udp level info facility auth,user
      若要將多租戶記錄轉送至遠端記錄伺服器，請在 structured-data 參數中指定專案和 VPC。例如， 
      set logging-server <server-ip>  proto udp level err structured-data proj=<project-shortId>
set logging-server <server -ip  proto udp level err structured-data vpc=<vpc-shortId>
      若要僅將稽核記錄轉送至遠端伺服器，請在 structured-data 參數中指定 audit="true"。例如： 
      set logging-server <server-ip> proto udp level info structured-data audit="true"
      所有 NSX 記錄均使用設施 local6。唯有當未設定設施篩選器或指定的設施中包含 local6 時，才應使用 messageid 和 structured-data 篩選器。
    2. 設定安全遠端記錄：
      • 若要使用 LI-TLS 通訊協定設定安全遠端記錄，請指定 proto li-tls 參數。例如：
        set logging-server vrli.prome.local proto li-tls level info messageid SWITCHING,ROUTING,FABRIC,SYSTEM,POLICY,HEALTHCHECK,SHA,MONITORING serverca intermed-ca-full-chain.crt

        如果設定成功，您將會收到不含任何文字的提示。若要查看伺服器憑證鏈結的內容 (中繼後面是根)，請以 root 使用者身分登入，並執行下列命令：

        keytool -printcert -file /image/vmware/nsx/file-store/intermed-ca-full-chain.crt
        例如， 
        root@nsx1:~# keytool -printcert -file /image/vmware/nsx/file-store/intermed-ca-full-chain.crt

      • 若要使用 TLS 通訊協定設定安全遠端記錄，請指定 proto tls 參數。例如：
        set logging-server vrli.prome.local proto tls level info serverca Orange-CA.crt.pem clientca Orange-CA.crt.pem certificate gc-nsxt-mgr-full.crt.pem key gc-nsxt-mgr.key.pem
        請注意下列事項：
        • serverCA 參數只需要根憑證，而不需要完整鏈結。
        • 如果 clientCA 與 serverCA 不同，則只需要根憑證。
        • 憑證應保留 NSX Manager 的完整鏈結 (應符合 NDcPP 標準 - EKU、BASIC 和 CDP (CDP - 可忽略此檢查))。
        您可以使用 keytool 命令檢查每個憑證的內容。例如， 
        keytool -printcert -file /image/vmware/nsx/file-store/Orange-CA.crt.pem
        keytool -printcert -file gc-nsxt-mgr-full.crt.pem

    3. 若要檢視記錄組態，請執行下列命令： 
      get logging-server
      例如， 
      nsx> get logging-servers
192.168.110.60 proto udp level info facility local6 messageid SYSTEM,FABRIC
192.168.110.60 proto udp level info facility auth,user
    4. 若要清除遠端記錄組態，請執行下列命令： 
      clear logging-servers
  2. 在 ESXi 主機上設定遠端記錄：
    1. 執行下列命令以設定 Syslog 和傳送測試訊息： 
      esxcli network firewall ruleset set -r syslog -e true
      esxcli system syslog config set --loghost=udp://<log server IP>:<port> --log-level=info
      esxcli system syslog reload
      esxcli system syslog mark -s "This is a test message"
    2. 您可以執行下列命令以顯示組態： 
      esxcli system syslog config get
