tomcat日志详解
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
4
5 #日志输出为输出到文件和输出到控制台
6 .handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
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)
9 #配置文件使catalina日志输出级别为FINE
10 1catalina.org.apache.juli.FileHandler.level = FINE
11 #catalina文件输出位置
12 1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
13 #catalina日志前缀为catalina
14 1catalina.org.apache.juli.FileHandler.prefix = catalina.
15
16 #配置文件使localhost日志输出级别为FINE
17 2localhost.org.apache.juli.FileHandler.level = FINE
18 #localhost文件输出位置
19 2localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
20 #localhost日志前缀为localhost
21 2localhost.org.apache.juli.FileHandler.prefix = localhost.
22
23 #配置文件使manager日志输出级别为FINE
24 3manager.org.apache.juli.FileHandler.level = FINE
25 #manager文件输出位置
26 3manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
27 #manager日志前缀为manager
28 3manager.org.apache.juli.FileHandler.prefix = manager.
29
30 #配置文件使host-manager日志输出级别为FINE
31 4host-manager.org.apache.juli.FileHandler.level = FINE
32 #host-manager文件输出位置
33 4host-manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
34 #host-manager日志前缀为host-manager
35 4host-manager.org.apache.juli.FileHandler.prefix = host-manager.
36
37 #配置文件使控制台日志输出级别为FINE
38 java.util.logging.ConsoleHandler.level = FINE
39 #控制台日志输出格式
40 java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
41
42 #localhost日志文件输出级别为INFO
43 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO
44 #localhost日志文件输出处理类2localhost.org.apache.juli.FileHandler
45 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler
46
47 #manager日志文件输出级别为INFO
48 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].level = INFO
49 #manager日志文件输出处理类3manager.org.apache.juli.FileHandler
50 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].handlers = 3manager.org.apache.juli.FileHandler
51
52 #host-manager日志文件输出级别为INFO
53 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager].level = INFO
54 #host-manager日志文件输出处理类4host-manager.org.apache.juli.FileHandler
55 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager].handlers = 4host-manager.org.apache.juli.FileHandler
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。

1.2.5 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
