Remember how you set up file handlers at different levels and with different output files in the previous
example? You can do the same thing here, in the configuration file, by adding and editing appenders,
files, and loggers. In the configuration file, under
</Console>
, add two new files to the appenders sec-
tion. In the code here,
ApacheLog-Warn
is stored at
c:/users/n12063/ApacheLogging_Warn.log
.
Make sure you use a filename that indicates a usable location on your own computer.
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36}
- %msg%n"/>
</Console>
<File name="ApacheLog-Info" filename=
"c:/users/n12063/ApacheLogging_Info.log">
<PatternLayout>
<pattern>[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1}
- %msg%n</pattern>
</PatternLayout>
</File>
<File name="ApacheLog-Warn" filename="src/ApacheLogging_Warn.log">
<PatternLayout>
<pattern>[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1}
- %msg%n</pattern>
</PatternLayout>
</File>
</Appenders>

Next, adjust the loggers section to add these new appenders to the root logger.
<Loggers>
<Root level="debug">
<AppenderRef ref="Console" level="fatal"/>
<AppenderRef ref="ApacheLog-Info" level="info"/>
<AppenderRef ref="ApacheLog-Warn" level="warn"/>
</Root>
</Loggers>
