tomcat日志类别
日志类别
- 服务器⽇志
catalina.out
- HTTP 访问⽇志
localhost_access_log.${date}.txt
- Web 应⽤⽇志
localhost.${date}.log
- 管理日志
manage.log
日志的级别
SEVERE (highest value) > WARNING > INFO > CONFIG > FINE > FINER > FINEST (lowest value)
OFF 关闭日志输出
ALL所有日志输出
日志级别的设置
通过修改conf/logging.properties文件设置日志输出级别和类型

在Linux下，tomcat会为对应的实例创建一个.out文件，放在$CATALINA_HOME/logs目录下，方便后期的排错使用。然而，该文件默认不能自动分割，在没有配置的情况下，该文件会不断的增大，日久天长，或许等到需要排错的时候，该文件的大小可以以G为单位了。所以，在配置完tomcat实例之后，建议修改一下启动文件，让.out文件随着日期的变化自增。
切割方法参考下面几个链接：
