I would like to have a log file that can be rolled at the beginning of the next day or if it's reached to specified file size. But my log file receives logging events from a remote appender.
My log.xml is:
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="30 seconds">
<property name="LOG_PORT" value="6000" />
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${LOG_DIR}/logname.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${LOG_DIR}/logname-%d{yyyy-MM-dd}.%i.zip</fileNamePattern>
<maxHistory>30</maxHistory>
<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>10MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
<encoder>
<pattern>%date{MMM dd yyyy HH:mm:ss.SSS}| [%thread] [%-5level] %logger{35}- %msg%n</pattern>
</encoder>
</appender>
<receiver class="ch.qos.logback.classic.net.server.ServerSocketReceiver">
<port>${myport}</port>
</receiver>
<root level="INFO">
<appender-ref ref="FILE" />
</root>
</configuration>
But with above configuration the log file is not rolled if the log file's size reached to 10 MB. So I wonder if Rolling policy still running for ServerSocketReceiver component.
Please help to advise me.

In my spring boot project,I am using spring logback.xml. I have a use case in which I have to roll over the file based on file size and date whichever is first and also I need to keep the count of rolled over files to 2 only. I was thinking to use following :
<configuration>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>test.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>test.%i.log.zip</fileNamePattern>
<maxIndex>2</maxIndex>
</rollingPolicy>
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>5MB</maxFileSize>
</triggeringPolicy>
<encoder>
<pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>
</encoder>
</appender>
<root level="DEBUG">
<appender-ref ref="FILE" />
</root>
</configuration>
But the above configuration achieves the use case rolling file based on filesize and keeping max count of rolled files to 2. But it does not do the rolling based on date. I need a rolling based on date also, in addition to file size while keeping the number of rolled files to 2. Is there any way to achieve this?
I think below should work. TimeBasedRollingPolicy uses pattern you provide for fileNamePattern which decides whether to append the data to existing file or new one.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>/logs/${appName}/${HOSTNAME}.log</file>
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- Rollover every day -->
<fileNamePattern>/logs/${appName}/${HOSTNAME}.%d{yyyy-MM-dd}.%i.log</fileNamePattern>
<maxHistory>2</maxHistory>
<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>5MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
</appender>
<root level="info">
<appender-ref ref="FILE" />

I am trying to create logger policy in a spring based project.
The issue I am facing is related to rolling policy. the logfile.log is created and is working fine but the rolling file rollingfile.log.%d{yyyy-MM-dd}.log is not created.
Given below is my logback.xml.
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="true" scan="true" scanPeriod="30 seconds">
<property name="LOG_PATH" value="D:/coinLogs" />
<property name="LOG_ARCHIVE" value="${LOG_PATH}/archive" />
<appender name="Console-Appender" class="ch.qos.logback.core.ConsoleAppender">
<layout>
<pattern>[%d{yyyy-MM-dd HH:mm:ss}] - [%X{requestId}] - %p %c -- %m%n</pattern>
</layout>
</appender>
<appender name="File-Appender" class="ch.qos.logback.core.FileAppender">

<appender-ref ref="File-Appender" />
</root>
</configuration>
any help will be appreciated. Thank you in advance :D
You need to specify ch.qos.logback.core.rolling.RollingFileAppender as class for your appender. A FileAppender can not roll.
I believe you're missing the %i parameter, which should be replaced by the rolling file index (i.e. 'mylog.2017-03-13.0.txt', 'mylog.2017-03-13.1.txt', etc.)
In addition, like Uwe Allner, I'm using RollingFileAppender instead of FileAppender.
(I also suggest adding a totalSizeCap to the configuration, in order to control to total size)
Here's my entire appender configuration:
<appender name="SQL_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${LOG_HOME}/mylog.txt</file>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>
%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level- %msg%n
</Pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<maxHistory>3</maxHistory>
<totalSizeCap>5GB</totalSizeCap>
<fileNamePattern>${LOG_HOME}/archived/mylog.%d{yyyy-MM-dd}.%i.txt.zip</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>20MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
</appender>
We are using logback as the logging framework for our java project... The logback configuration is as given below
<configuration debug="true">
<property name="LOG_HOME" value="/etc/report-synchronizer" />

<discriminator>
<key>modulename</key>
<defaultValue>unknown</defaultValue>
</discriminator>
<sift>
<appender name="FILE-${modulename}"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>${LOG_HOME}/${modulename}-%d{yyyy-MM-dd}.%i.log
</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<!-- or whenever the file size reaches 5MB -->
<maxFileSize>5MB</maxFileSize>
<!-- Number of days for which the files will be kept -->
<maxHistory>10</maxHistory>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>

We are using java cassandra driver in the project. All the logs generated by the cassandra driver are getting mixed up with our application logs. Is there any way to separate the cassandra driver logs to a separate file
Thanks in advance
Declare a logger with name com.datastax.driver, a dedicated appender, and additivity set to false. This way you will confine the driver logs to its appender.
The following example should give you a good start:
<logger name="com.datastax.driver" level="INFO" additivity="false">
<appender-ref ref="DRIVER"/>
</logger>
<appender name="DRIVER" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${LOG_HOME}/${modulename}-driver.log</file>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%d [%thread] %level %mdc %logger{35} - %msg%n</pattern>
</layout>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>${LOG_HOME}/${modulename}-driver-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<!-- or whenever the file size reaches 5MB -->
<maxFileSize>5MB</maxFileSize>
<!-- Number of days for which the files will be kept -->
<maxHistory>10</maxHistory>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
</appender>
I use Logback 1.0.10 and I'm trying to get log file rolling to work, but no matter what I do, whenever a new day comes, it just truncates the log file.
Any ideas? I use Java 6 and this is for a webapp running in Tomcat 6 on a Windows 2008 server.
<?xml version="1.0" encoding="UTF-8" ?>
<configuration scan="true" scanPeriod="10 seconds">
<!--Daily rolling file appender -->
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${log.dir}/${log.name}.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<FileNamePattern>${log.name}.%d{yyyy-MM-dd}.log</FileNamePattern>
</rollingPolicy>
<encoder>
<pattern>%d %-5level %logger{35} - %msg%n</pattern>
</encoder>
</appender>
<root>
<level value="${log.level}" />
<appender-ref ref="FILE" />
</root>
</configuration>
I realize now that I forgot ${log.dir} in FileNamePattern and ta-da, the old log file was in the parent directory.
I've been trying to set up a simple logback project to roll my log files by date and by filesize, and so far I have been unable to get my appender to roll over to another file. Instead, it writes to the log specified by the <file/> tag.
Here is my logback.xml configuration file:
<?xml version="1.0"?>
<configuration scan="true" scanPeriod="10 seconds">
<appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">

</layout>
</appender>
<appender name="milliroller" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>log/output.log</file>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
</layout>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>log/mylog-%d{yyyy-MM-dd}.%i.txt</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>1KB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
</appender>
<root level="DEBUG">
<appender-ref ref="stdout"/>
<appender-ref ref="milliroller"/>
</root>
<logger name="com.tkassembled.logback" level="DEBUG"/>
</configuration>
At first glance, it looks like it should work, right? Is there something I'm doing wrong? My entire, buildable project is available in a zip here: http://www.mediafire.com/file/2bxokkdyz2i/logback.zip
Although this is an old question, I felt that a working answer is appropriate to help anyone who requires this kind of implementation.
I use the following logback configuration to provide an HTML log, rolled over by date and filesize, as well as logging to console for debugging output.
Logfiles are stored in a logs directory with a name of logFile.html while its active, and logFile.2013-mm-dd.i.html when it rolls over, where i is the number of 50MB log files. For instance logFile.2013-01-07.0.html.

Since logback 1.1.7 (released March 2016) a new policy called SizeAndTimeBasedRollingPolicy is available that dramatically simplifies what you need to do:
<appender name="ROLLING" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>app.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<fileNamePattern>app-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
<maxFileSize>10MB</maxFileSize>
<maxHistory>30</maxHistory>
<totalSizeCap>1GB</totalSizeCap>
</rollingPolicy>
<encoder>
<pattern>%msg%n</pattern>
</encoder>
</appender>
