parsing - Fluentbit 与 mycat 多行解析

Question

我想通过 EFK 制作一个日志管理系统。我已经尝试了好几天让我的多行 mycat 日志解析器与 fluent-bit 一起工作。

我的 fluentbit 配置:

parsers.conf:
    [PARSER]
      Name        mycat_error_log_parser_head
      Format      regex
      Regex       ^(?<time>(\d)+(-\d+)+(\S)+\W(\S)+)(\s+)(?<action>\S+)(\s+)(?<on>\S+)
      Time_Key    time
      Time_Format %Y-%m-%d %H:%M:%S.%L
      Time_Keep   On

    [PARSER]
      Name        mycat_error_log_parser
      Format      regex
      Regex       ^(?<time>(\d)+(-\d+)+(\S)+\W(\S)+)(\s+)(?<action>\S+)(\s+)(?<on>\S+)(\s+)(?<content>(.|\s)*)$
      Time_Key    time
      Time_Format %Y-%m-%d %H:%M:%S.%L
      Time_Keep   On

fluent-bit.conf
    [INPUT]
        Name tail
        tag mycat
        path /var/log/mycat.log
        Multiline On
        Parser_Firstline mycat_error_log_parser_head
        Parser mycat_error_log_parser
        Path_Key file

和 mycat.log 看起来像这样:

mycat.log
2018-08-02 09:59:41.205  INFO [$_NIOConnector] (io.mycat.backend.datasource.PhysicalDatasource.getConnection(PhysicalDatasource.java:529)) - no ilde connection in pool,create new connection for hostS1 of schema mysql

我想我现在很接近了，但到目前为止还没有运气。

在我的 kibana 中。我得到以下结果:

我的多行错误日志丢失了。但我在rubular中测试它正常解析

任何帮助，将不胜感激。

此配置适用于您的日志文件，Fluent Bit 使用此配置发布了 5 个文档以进行 Elasticsearch 。

   parsers.conf
    [PARSER]
      Name        mycat_error_log_parser_head
      Format      regex
      Regex       ^(?<time>(\d)+(-\d+)+(\S)+\W(\S)+)(\s+)(?<action>\S+)(\s+)(?<on>\S+)(\s+)(?<content>.*)
      Time_Key    time
      Time_Format %Y-%m-%d %H:%M:%S.%L
      Time_Keep On

    [PARSER]
      Name        mycat_error_log_parser
      Format      regex
      Regex       (?m-ix)^(?<time>(\d)+(-\d+)+(\S)+\W(\S)+)(\s+)(?<action>\S+)(\s+)(?<on>\S+)(\s+)(?<content>.*)
      Time_Key    time
      Time_Format %Y-%m-%d %H:%M:%S.%L
      Time_Keep On


  fluent-bit.conf
   [INPUT]
      Name tail
      tag mycat
      path /var/log/mycat.log
      Multiline On
      Parser_Firstline mycat_error_log_parser_head
      Parser_1 mycat_error_log_parser
      Path_Key file

对问题中的配置进行了两项更改 - [PARSER] 部分中的 Regex 配置已更改，而 Parser 已更改为 [INPUT] 部分中的 Parser_1。

我在多行解析中遇到过类似的问题，我的观察是 Parser_FirSTLine 应该覆盖多行消息中的整个第一行，而 Parser_1 .. Parser_N 应该覆盖多行消息的整个结构。
