Mysql logstash配置中的JDBC插件问题

我有这个配置文件（logstash）：

用于将数据另存为mySQL数据库。但它不适用于错误消息（列“ip”，“事件”不能为空）

我认为'jdbc.statement'的语法是错误的，我正在尝试修复它。 “output.elasticsearch”工作得很好

        ]
    },
          "tags" => [
        [0] "beats_input_codec_plain_applied"
    ]
}

如何使用“writetime”和“event”值？ 请给我一些建议

 "log" => {
           "userid" => "192.168.43.129",
        "writetime" => "2020/11/23 15:31:51",
           "target" => "crackme.exe - PID: 5528 - Module: ntdll.dll - Thread: Main Thread 3240 (switched from 19C0)",
            "event" => "dbgRestart"},

如果event是log对象中的一个字段，那么在logstash中，您将其称为“[log][event]”。[log.event]是指名称中有句点的字段。与“[log][userid]”类似

 "log" => {
           "userid" => "192.168.43.129",
        "writetime" => "2020/11/23 15:31:51",
           "target" => "crackme.exe - PID: 5528 - Module: ntdll.dll - Thread: Main Thread 3240 (switched from 19C0)",
            "event" => "dbgRestart"},
