记录分析以根据日志消息查询日志

我有一个Java应用程序输出格式的日志

时间戳UUID1的一些信息
时间戳UUID1更多信息
时间戳UUID1 x = 1

时间戳UUID2的一些信息
时间戳UUID2更多信息
时间戳UUID2 x = 2

时间戳UUID3的一些信息
时间戳UUID3更多信息
时间戳UUID3 x = 1

我想使用Elsatic Search，LogStash和Kibana实现日志分析框架 . 是否可以仅根据X值获取日志？

例如：-

如果我查询X = 1，我应该只得到以下日志 .

时间戳UUID1的一些信息
时间戳UUID1更多信息
时间戳UUID1 x = 1
时间戳UUID3的一些信息
时间戳UUID3更多信息
时间戳UUID3 x = 1

如果我查询X = 2，我应该只得到以下日志 .

时间戳UUID2的一些信息
时间戳UUID2更多信息
时间戳UUID2 x = 2

我控制着日志消息格式 . 如果不能直接进行此查询，我也可以更改消息格式 .

更新1：

我会更具体一点 .

以下是我的日志声明 .

MDC.put("uuid", UUID.randomUUID().toString());
    logger.info("Assigning value to the variable : {}", name);
    this.setVal(value.getVal());
    logger.info("{} = {}", name, value.getVal());
    logger.info("Assigned value {} to the variable : {}", value.getVal(),
            name);
    MDC.clear();

我使用UDP在Logstash中收到了日志语句 . 我收到的消息就像 .

}

有2个UUID

"d5513e4c-de3b-4144-87e4-87b077ac8056" for "Y = 1"
"ab17b842-8348-4474-98e4-8bc2b8dd6781" for "X = 1"

每个UUID还有两条消息 . 我想把它们组合成一个单一的事件 .

我不确定，如何为这种情况编写多行过滤器 .

filter {
  multiline {
    pattern => "."
    what => "previous"
    stream_identity => "%{uuid}"
  }
}

看来，“模式”和“什么”是必填字段 . 我应该为这些领域提供什么 . 我如何使用Stream Identity？

请指出我正确的方向 .

谢谢，保罗
