您可以配置 NSX-T Data Center 设备和 Hypervisor 以将日志消息发送到远程日志服务器。

NSX Manager、NSX Edge 和 Hypervisor 支持远程日志记录。必须分别在每个节点上配置远程日志记录。

对于协议参数，选项包括 UDP、TCP、LI 以及安全协议 TLS 和 LI-TLS。Log Insight 日志服务器支持所有协议。仅当日志服务器为 Log Insight 时，才能使用协议 LI 和 LI-TLS。使用 LI 或 LI-TLS 的好处是它们可优化网络使用情况。如果日志服务器为 Log Insight，建议使用 LI 或 LI-TLS。如果无法使用 LI，则 TCP 的优势是更加可靠，而 UDP 的优势是需要较少的系统和网络开销。

在 KVM 主机上，NSX-T Data Center 安装软件包会通过将配置文件置于 /etc/rsyslog.d 目录中来自动配置 rsyslog 守护进程。

前提条件

  • 请自行熟悉 CLI 命令 set logging-server。有关详细信息，请参见《NSX-T Data Center 命令行界面参考》。
  • 如果指定安全协议 TLS 或 LI-TLS，则服务器和客户端证书必须存储在每个 NSX-T Data Center 设备上的 /image/vmware/nsx/file-store 中。请注意，仅当使用 NSX-T Data Center CLI 配置导出程序时，才需要文件存储中的证书。如果使用 API，则无需使用文件存储。完成 syslog 导出程序配置后，必须删除此位置中的所有证书和密钥，以避免潜在的安全漏洞。
  • 要配置与日志服务器的安全连接，请确认服务器配置了 CA 签名的证书。例如，如果您使用 Log Insight 服务器 vrli.prome.local 作为日志服务器，则可以从客户端运行以下命令以查看服务器上的证书链：
    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
 0 s:/C=US/ST=California/L=HTG/O=GSS/CN=vrli.prome.local
   i:/C=US/L=California/O=GS/CN=Green Intermediate Certification Authority
 1 s:/C=US/L=California/O=GS/CN=Green Intermediate Certification Authority
   i:/C=US/L=California/O=GS/CN=Orange Root Certification Authority
 2 s:/C=US/L=California/O=GS/CN=Orange Root Certification Authority
   i:/C=US/L=California/O=GS/CN=Orange Root Certification Authority
---
DONE

过程

  1. 要在 NSX-T Data Center 设备上配置远程日志记录，请执行以下操作：
    1. 运行以下命令以配置日志服务器和要发送到日志服务器的消息类型。可以将多个设备或消息 ID 指定为逗号分隔列表（不含空格）。 
      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>]
      您可以多次运行该命令来添加多个配置。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
      要仅将审核日志转发到远程服务器，请在 structured-data 参数中指定 audit="true"。例如： 
      set logging-server <server-ip> proto udp level info structured-data audit="true"
      所有 NSX 日志均使用程序模块 local6。仅当未设置程序模块筛选器或指定程序模块中包含 local6 时，才应使用 messageid 和 structured-data 筛选器。
    2. 配置安全远程登录：
      • 要使用协议 LI-TLS 配置安全远程日志记录，请指定 proto li-tls 参数。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
        如果配置成功，您将收到一条不含任何文本的提示。要查看服务器证书链（中间证书后跟根证书）的内容，请以 root 的身份登录，然后运行以下命令： 
        root@nsx1:~# keytool -printcert -file /image/vmware/nsx/file-store/intermed-ca-full-chain.crt

      • 要使用协议 TLS 来配置安全远程日志记录，请指定 proto tls 参数。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
        请注意以下事项：
        • 对于 serverCA 参数，只需提供根证书，而不是整个链。
        • 如果 clientCA 不同于 serverCA，则只需提供根证书。
        • 该证书应该包含 NSX Manager 的完整链（应兼容 NDcPP - EKU、BASIC 和 CDP（CDP - 可以忽略这项检查））。
        您可以检查每个证书的内容。例如：

    3. 要查看日志记录配置，请运行 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. 要清除远程日志记录配置，请运行以下命令： 
      nsx> clear logging-servers
  2. 要在 ESXi 主机上配置远程日志记录，请执行以下操作：
    1. 运行以下命令以配置 syslog 并发送测试消息： 
      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. 可以运行以下命令以显示配置： 
      esxcli system syslog config get
  3. 要在 KVM 主机上配置远程日志记录，请执行以下操作：
    1. 针对您的环境编辑文件 /etc/rsyslog.d/00-vmware-remote-logging.conf。
      如果该文件不存在，请创建该文件。用于向该组和其他组授予读取权限的典型默认权限足以满足需求。
    2. 将以下行添加到该文件中： 
      *.* @<ip>:514;NsxLogfmt
    3. 运行以下命令： 
      service rsyslog restart
