My application is using logback. Now I want to use perf4j 0.9.16 for my current application. The configuration comes from http://perf4j.codehaus.org/apidocs/org/perf4j/logback/package-summary.html
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<FileNamePattern>/var/log/myapp/myapp.log.%d{yyyy-MM-dd}</FileNamePattern>
</rollingPolicy>
<encoder>
<pattern>%d %5p | %t | %-55logger{55} | %m %n</pattern>
</encoder>
</appender>
<appender name="perf4jFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<FileNamePattern>/var/log/myapp/myapp.timer.%d{yyyy-MM-dd}</FileNamePattern>
</rollingPolicy>
<encoder>
<Pattern>%date %-5level [%thread] %logger{36} [%file:%line] %msg%n</Pattern>
</encoder>
</appender>
<logger name="org.perf4j.TimingLogger" level="DEBUG" additivity="false">
<appender-ref ref="perf4jFileAppender"/>
</logger>
<root level="INFO">
<appender-ref ref="file"/>
</root>
myapp.log is still worked as before but myapp.timer is empty file. It logs to console like this:
start[1430914241369] time[4] tag[firstMethod.success] message[OK]
start[1430914241375] time[0] tag[secondMethod.success] message[OK]
I've tried this perf4j settings for logback.xml, but it can't help. Any idea?
Thank you.

This happens when you pass your own logger to one of the Slf4JStopWatch constructors. Either use the default constructor (new Slf4JStopWatch()) or change your config file to something like
<logger name="com.example.MyOwnPerformanceLogger" level="DEBUG" additivity="false">
<appender-ref ref="perf4jFileAppender"/>
</logger>
org.perf4j.TimingLogger is just the default logger name for stopwatches.
By the way: One of your <pattern> elements is in capitalized.
