使用 Aria Operations for Logs 查看统一安全日志

通过使用 Aria Operations for Logs，可以查看 NSX 环境的安全流日志。

以下安全功能支持流量日志记录：

统一安全日志

所有安全垂直项都会在节点上的单个日志文件中生成统一安全流日志，并以统一安全日志格式保存这些日志。此单个日志将导出到为 Aria Operations for Logs 配置的 syslog 服务器。然后，Aria Operations for Logs 将处理日志，以使用 NSX 内容包提供进一步的日志管理、分析并显示日志。

在 Aria Operations for Logs 上显示日志

NSX 内容包中的“NSX - 统一安全流日志”仪表板显示了一些图表小组件，这些小组件以直观的方式显示了安全流日志。

Aria Operations for Logs 内容包是一个插件，其中包含与特定产品或日志集相关的仪表板、已提取的字段、保存的查询和警示。

NSX 内容包可从 Aria Operations for Logs 商城获取。

有关 Aria Operations for Logs 以及如何从内容包商城安装内容包的详细信息，请参见 Aria Operations for Logs 文档中的“从内容包商城安装内容包”一章。

前 N 条和过去 X 小时

您还可以使用交互式分析和内容包查询 Aria Operations for Logs 中的事件，获取过去 X 小时内的前 N 条信息。

远程日志记录服务器

要将日志发送到远程日志记录服务器，必须分别在每个节点上为 NSX 设备和 Hypervisor 配置远程日志记录。

注：要将日志发送到 syslog 服务器，您必须为 NSX Manager 上的特定规则启用日志记录。

有关详细信息，请参见配置远程日志记录。

如果远程日志服务器不接收日志，请参见对 Syslog 问题进行故障排除。

统一安全日志格式

在 Edge 节点上，统一安全流日志都存储在 /var/log/syslog 中。您可以用 root 用户身份登录，并使用 grep 命令搜索此文件以查找统一日志。例如：

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