如何在思科邮件安全设备(ESA)上创建并配置日志？
答案
思科邮件安全设备(ESA)的一个重要功能是其日志记录功能。ESA上的AsyncOS可以生成多种类型的日志，记录各种类型的信息。日志文件包含系统各个组件的常规操作和异常的记录。此信息在监控Cisco ESA时以及在排除故障或检查性能时很有用。
可以使用CLI的“logconfig”命令或通过GUI的“System Administration”（系统管理） > “Log Subscriptions”（日志订阅） >“Add Log Subscription...”（添加日志订阅……）配置和创建日志
以下是使用CLI创建LDAP调试日志订阅的示例：。

4. "brightmail" Type: "Symantec Brightmail Anti-Spam Logs" Retrieval: FTP Poll
