记录分析以根据日志消息查询日志

标签: java elasticsearch logstash kibana

我有一个Java应用程序,它以

格式输出日志

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"对于" Y = 1"
" ab17b842-8348-4474-98e4-8bc2b8dd6781"对于" 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}"
  }
}




"模式"和"什么"似乎是必填字段。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

如果X是一些唯一值,那么使用kibana过滤器应该可以实现这一点,但是如果显示所示格式的日志,则需要使用多行过滤器将条目连接在一起。

有了这个,你可能会使用类似

的查询
message: "X=1"

您需要合并邮件(请参阅支持stream_identity的multiline {}过滤器),然后常规查询将返回相应的邮件。
