您可以設定 NSX-T Data Center 應用裝置及 Hypervisor 以傳送記錄訊息至遠端記錄伺服器。

NSX ManagerNSX 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。

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。Log Insight 記錄伺服器支援所有通訊協定。僅當記錄伺服器為 Log Insight 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 Log Insight,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。

在 KVM 主機上,NSX-T Data Center 安裝套件透過將組態檔置於 /etc/rsyslog.d 目錄中,以自動設定 rsyslog 精靈。

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-T Data Center Command-Line 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-T Data Center 應用裝置上的 /image/vmware/nsx/file-store 中。請注意,只有在使用 NSX-T Data Center 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 Log Insight 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:
    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
    Certificate chain

    DONE

程序

  1. NSX-T Data Center 應用裝置上設定遠端記錄:
    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:
      nsx> set logging-server 192.168.110.60 proto udp level info facility local6 messageid SYSTEM,FABRIC
      nsx> set logging-server 192.168.110.60 proto udp level info facility auth,user
      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 messageidstructured-data 篩選器。
    2. 設定安全遠端登入:
      • 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 的身分登入,並執行下列命令:
        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 clientCAserverCA 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))。
        您可以檢查每個憑證的內容。例如:

    3. 若要檢視記錄組態,請執行 get logging-server 命令。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:
      nsx> clear logging-servers
  2. 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
  3. 在 KVM 主機上設定遠端記錄:
    1. 針對您的環境編輯檔案 /etc/rsyslog.d/00-vmware-remote-logging.conf
      如果該檔案不存在,請建立檔案。將讀取權限授與群組與其他人的一般預設權限已足夠。
    2. 將下列行新增至檔案:
      *.* @<ip>:514;NsxLogfmt
    3. 執行下列命令:
      service rsyslog restart
