Question

这是系统报告的事件，当非sudo用户尝试执行sudo命令（使用的命令为sudo su）

Jan 24 14:02:49 hostn-1212 sudo: test-arun-user : user NOT in sudoers ; TTY=pts/2 ; PWD=/home/test-arun-user ; USER=root ; COMMAND=/bin/bash

但是Auditbeat未捕获此事件。我的Auditbeat配置文件如下：

  mem:
    events: 4096
    flush:
      min_events: 2048
      timeout: 1s

我得到了大多数事件，但是未捕获到如上所示在日志中报告的事件。我想知道是否可以对配置进行任何操作。请帮忙。

如何在Auditbeat 6.4.0中捕获sudo事件报告？
