Question

我有一个日志行（多行匹配），如下所示：

3574874    14/Jul/2016 20:42:37 +0000  ERROR [http-bio-0.0.0.0-8443-exec-128] error_jsp            _jspService    > could not lock: [com.myCompany.myProject.bean.scheduling.Area#6306]; SQL [/* UPGRADE lock com.myCompany.myProject.bean.scheduling.Area */ select Area_id from Area_ID where Area_id =? and Area_Version =? for update]; nested exception is org.hibernate.exception.LockAcquisitionException: could not lock: [com.myCompany.myProject.bean.scheduling.Area#6306]

我的模式文件就像这样：

    # AW Tomcat formatting
    TOMCAT_DATE %{MONTHDAY}[./-]%{MONTH}[./-]%{YEAR}
    TOMCAT_TS %{BASE10NUM}
    #%{BASE10NUM}
    TOMCAT_TIME %{HOUR}:%{MINUTE}(?::%{SECOND})(?![0-9])
    TOMCAT_THREAD \[(.+?)\]
    TOMCAT_CLASS [A-Za-z0-9]+
    TOMCAT_CLASS_METHOD %{NOTSPACE}
    TOMCAT_TIMESTAMP %{TOMCAT_DATE}[\s]+%{TOMCAT_TIME}
    TOMCAT_MESSAGE .+
    TOMCAT_IP %{IP}
    TOMCAT_DATA %{NOTSPACE}

    TOMCAT_LOG (?:%{TOMCAT_TS:log_ts})[\s]+(?:%{TOMCAT_TIMESTAMP:log_timestamp})[\s]+%{INT}[\s]+(?:%{LOGLEVEL:log_level})[\s]+(?:%{TOMCAT_THREAD:thread})[\s]+(?:%{TOMCAT_CLASS:class_name})[\s]$

当我在logstash中看到这个时，似乎线程的代码与线程的匹配要多得多......它一直匹配到[com.myCompany.myProject.bean.scheduling.MyClass＃6306] ;

当我把空间中的线程和正则表达式放在regexr或regex101之后，我无法重新创建它：

\[(.+?)\][\s]+

有没有人了解为什么正则表达式在所有地方工作但是logstash？此外，这也适用于我传入的tomcat日志的大约99.5％....

您的日志中有+。您需要将其与\+匹配，或将其设为\+?

TOMCAT_LOG (?:%{TOMCAT_TS:log_ts})\s+(?:%{TOMCAT_TIMESTAMP:log_timestamp})\s+\+?%{INT}\s+(?:%{LOGLEVEL:log_level})\s+(?:%{TOMCAT_THREAD:thread})\s+(?:%{TOMCAT_CLASS:class_name})\s*$
                                                                             ^^^

Logstash模式匹配超过它应该
