I need guidance for a logging requirement I am having.
My application got two services - upload and download.
I need to maintain separate logs for both - So far I have done below in logback.xml
<appender name="DownloadAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>download.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<fileNamePattern>download.log_%d{yyyy-MM-dd}_%i.zip</fileNamePattern>
<maxFileSize>100MB</maxFileSize>
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%date [%thread] %-5level %logger{35} - %msg%n</pattern>
</encoder>
<filter class="ch.qos.logback.core.filter.EvaluatorFilter">
<evaluator> <!-- defaults to type ch.qos.logback.classic.boolex.JaninoEventEvaluator -->
<expression>logger.equals("DownloadLogger")</expression>
</evaluator>
<OnMismatch>DENY</OnMismatch>
<OnMatch>ACCEPT</OnMatch>
</filter>
</appender>
<appender name="UploadAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>upload.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<fileNamePattern>upload.log_%d{yyyy-MM-dd}_%i.zip</fileNamePattern>
<maxFileSize>100MB</maxFileSize>
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%date [%thread] %-5level %logger{35} - %msg%n</pattern>
</encoder>
<filter class="ch.qos.logback.core.filter.EvaluatorFilter">
<evaluator> <!-- defaults to type ch.qos.logback.classic.boolex.JaninoEventEvaluator -->
<expression>logger.equals(UploadLogger")</expression>
</evaluator>
<OnMismatch>DENY</OnMismatch>
<OnMatch>ACCEPT</OnMatch>
</filter>
</appender>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>
%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
</pattern>
</encoder>
</appender>
<logger name="DownloadLogger" level="DEBUG" additivity="true">
<appender-ref ref="DownloadAppender" />
</logger>
<logger name="UploadLogger" level="DEBUG" additivity="true">
<appender-ref ref="UploadAppender" />
</logger>
<root level="DEBUG">
<appender-ref ref="STDOUT"/>
</root>
Usage of defined loggers in application is used by respective service classes.
ie classes of upload service obtain logger by
LoggerFactory.getLogger("UploadLogger")
and vice-versa for DownloadLogger.
Upon running the service I notice that only upload.log is created and filled in.
download.log gets created but no content are logged in it .
I suspect usage of filter is incorrect but I couldn't find any solution yet such that both log files can be maintained properly.
Can someone please help me how to correct the config?
The above config is fit for the purpose. The problem was in the way logback.xml was provided as command line argument.
The problem was resolved after providing logback.xml with -Dlogback.configurationFile

I'm trying to configure logback so that certain packages are logged differently depending on the appender. I have a ConsoleAppender and a RollingFileAppender. I want TRACE level logging for the ConsoleAppender and I want only two packages logged to the RollingFileAppender. What ends up happening is my ConsoleAppender and RollingFileAppender behave exactly the same.
Here is my logback.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration>
<configuration>
<property resource="logback.properties" />

I want it to only show me INFO level logs or greater. So, I added the ThresholdFilter and set its level to INFO. Doing this worked for the RollingFileAppender (where one includes INFO and greater and the other includes DEBUG and greater).
This didn't make a difference as the console statements continue to include DEBUG level statements. Can anyone tell me why?
I can't guarentee that this will work, didn't actually test the setup.
Add element after your .
<logger name="ch.qos.logback" level="INFO">
<appender-ref ref="console" />
</logger>
That should modify the logging level of only the referenced appenders to the desired level.
See Logback docs for some more info on the thinking here.
I try to use logback for a project and want to have a classic daily rollover.
I cant make it work : all logs keep in the default file.
Either I badly understood the rolling policy, or it dont work corectly. In fact I thought that I I run for instance my tomcat one minute after the last log, the "current" log file is backed up in another file...
For test purpose I tried a "minutely" rollover. Someone see something horrible in my config ? :
<appender name="dailyRollingFileAppender"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>C:/myProject/programs/apache-tomcat-8.0.21-presentation/logs/presentation-log.log

<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover -->

<timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>10MB</maxFileSize>

<!-- keep 1 day history -->

I'm trying redirect all my logs to a file but it's not working. It only displays on console.
Here is my configuration:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">

<logger name="com.detc.resources" level="INFO" />
<root level="debug">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
</root>
</configuration>
What is wrong on my configuration?
Thank in advance.
Configuration looks fine. I would suggest two things:
Check the file permissions, and ownerships on /Users/Plac/Development/logs/detc.log, right up to the root.
Make sure that the logger is using the same config file. To be certain, delete/Move other instances of config file from other directories like bin.
i am using logback in my java web appliaction. here's my "logback.xml" file.

today is june 1st 2013, all my old logs are overwrited and no *.gz created.
somebody help me, please.
Try to do like this, Hope it will work for you.
<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>${LOGDIR}/filename.log</File>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily -->
<FileNamePattern>${LOGDIR}/file.%d{yyyy-MM-dd}.%i.log.gz
</FileNamePattern>
<!-- keep 30 days' worth of history -->
<MaxHistory>30</MaxHistory>
<!-- or whenever the file size reaches 10MB -->
<timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>10MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>%date [%thread] %-5level %logger{36} - %msg%n
</Pattern>
</encoder>
</appender>
The above code will compress your file on the day basis or If the log file size exceeds 10MB.
Note : I have added "%i" in filePattern, It will iterate your file name as file1,file2 etc.
Try adding <cleanHistoryOnStart>true</cleanHistoryOnStart> so that the rollover happens on next startup, as if it wasn't running at the time of rollover it wouldn't have happened.
