tomcat日志级别

Log level Description

• SEVERE(highest)? Captures exception and Error
• WARNING? Warning messages
• INFO? Informational message, related to the server activity
• CONFIG? Configuration message
• FINE? Detailed activity of the server transaction (similar to debug)
• FINER? More detailed logs than FINE
• FINEST(least)? Entire flow of events (similar to trace)

比如看下如下文件配置的日志级别：

localhost.org.apache.juli.FileHandler.level = FINE
localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
localhost.org.apache.juli.FileHandler.prefix = localho
```st.
