Question

我正在尝试将与CentOS 7有关的身份验证发送给Elasticsearch。奇怪的是，我没有收到任何身份验证事件。

当我运行 debug命令 auditbeat -c auditbeat.conf -d -e "*"时，发现如下内容：

 {
      "@timestamp": "2019-01-15T11:54:37.246Z",
      "@metadata": {
        "beat": "auditbeat",
        "type": "doc",
        "version": "6.4.0"
      },
      "error": {
        "message": "failed to set audit PID. An audit process is already running (PID 68504)"
      },
      "beat": {
        "name": "env-cs-westus-devtest-66-csos-logs-es-master-0",
        "hostname": "env-cs-westus-devtest-66-csos-logs-es-master-0",
        "version": "6.4.0"
      },
      "host": {
        "name": "env-cs-westus-devtest-66-csos-logs-es-master-0"
      },
      "event": {
        "module": "auditd"
      }
    }

还存在如下错误行：

Failure receiving audit events {"error": "failed to set audit PID. An audit process is already running (PID 68504)"}

Auditbeat版本 auditbeat版本6.4.0（amd64），libbeat 6.4.0

有人遇到过类似的问题并得到了解决吗？

注意：此用于Auditbeat的配置成功捕获了Ubuntu的身份验证事件

Answer 1

因此，我在Elastic Beats论坛上发布了相同的内容，并找到了解决方案。您可以找到相同的here

根据他们的建议，关闭审核的服务将使Audibeat捕获审核事件。我尝试了同样的方法，它为我工作。但是我不确定关闭审计的含义。因此，我可能会切换到基于Filebeat的解决方案。

Auditbeat无法在CentO 7中接收身份验证事件
