tomcat 日志详解

Tomcat 前端之家
前端之家收集整理的这篇文章主要介绍了tomcat 日志详解，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

1 tomcat  日志详解

1.1  tomcat 日志配置文件

　　tomcat 对应日志的配置文件：tomcat目录下的/conf/logging.properties。

　　tomcat 的日志等级有：日志输出级别：SEVERE (最高级别) > WARNING > INFO > CONFIG > FINE > FINER(精心) > FINEST (所有内容,最低级别)

　　tomcat  有五类日志 ：catalina、localhost、manager、admin、host-manager

　　/conf/logging.properties 配置文件：

 1 #可配置项(5类日志)：catalina、localhost、manager、admin、host-manager
 2 handlers = 1catalina.org.apache.juli.FileHandler,2localhost.org.apache.juli.FileHandler, 3 3manager.org.apache.juli.FileHandler,4host-manager.org.apache.juli.FileHandler,java.util.logging.ConsoleHandler

 5 #日志输出为输出到文件和输出到控制台
 6 .handlers = 7 
 8 #日志输出级别：SEVERE (最高级别) > WARNING > INFO > CONFIG > FINE > FINER(精心) > FINEST (所有内容,最低级别)

19 2localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/20 #localhost日志前缀为localhost

1.2  tomcat 日志文件详解

　tomcat  有五类日志 ：catalina、localhost、manager、admin、host-manager

　1.2.1 catalina.out ：

catalina.out即标准输出和标准出错，所有输出到这两个位置的都会进入catalina.out，这里包含tomcat运行自己输出的日志以及应用里向console输出的日志。默认这个日志文件是不会进行自动切割的，我们需要借助其他工具进行切割（注意：catalina.out文件如果过大会影响）

    1.2.2 catalina.YYYY-MM-DD.log

　catalina.{yyyy-MM-dd}.log是tomcat自己运行的一些日志，这些日志还会输出到catalina.out，但是应用向console输出的日志不会输出到catalina.{yyyy-MM-dd}.log,它是tomcat的启动和暂停时的运行日志，注意，它和catalina.out是里面的内容是不一样的。

　1.2.3 localhost.YYYY-MM-DD.log

　localhost.{yyyy-MM-dd}.log主要是应用初始化(listener,filter,servlet)未处理的异常最后被tomcat捕获而输出的日志,它也是包含tomcat的启动和暂停时的运行日志,但它没有catalina.2018-09-19.log 日志全。它只是记录了部分日志。

　1.2.4 localhost_access_log.YYYY-MM-DD.txt

　localhost_access_log.2018-09-19.txt：这个是访问tomcat的日志，请求时间和资源，状态码都有记录。

　1.2.5 host-manager.YYYY-MM-DD.log

    host-manager.2018-09-19.log：这个估计是放tomcat的自带的manager项目的日志信息的，未看到有什么重要的日志信息。

　 1.2.6 manager.YYYY-MM-DD.log

　  manager.2018-09-19.log  ：　这个是tomcat manager项目专有的日志文件.

1.3 tomcat  日志文件切割

　　tomcat  的  catalina.out  文件tomcat 是不会进行日志切割的，当这个文件大于2G  时，会影响tomcat的运行。那么我们需要对这个文件进行日志切割，切割的方法有很多种：

　　第一种：

　　通过系统自带的切割工具：logrotate来进行切割。

　　第二种:

　　使用logj4进行切割日志。

　　第三种：

　　使用用cronolog分割tomcat的catalina.out文件 

　　以上三种方法见：https://www.cnblogs.com/happy-king/p/9193401.html
