I've seen many examples of configuring logging in Spring Boot, but what I look for is the simplest way to get the job done modifying this pattern in my application.properties:
logging.pattern.file= %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n"
logging.file=/Users/alessandroargentieri/Desktop/try/application.log
This works pretty fine but what I would like to get is set a MB limit for the single file and set that every day I want to have a different log file (with the date in the filename).
Is possible to get this adding some lines in the application.properties without using XML or JSON files?
I think you need to override the default logging config with your own custom configuration. Spring boot provide logging support with minimum configuration and it's limited. It uses internally base.xml file which includes the below file-appender.xml:
<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<encoder>
<pattern>${FILE_LOG_PATTERN}</pattern>
</encoder>
<file>${LOG_FILE}</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>${LOG_FILE}.%i</fileNamePattern>
</rollingPolicy>
<triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<MaxFileSize>10MB</MaxFileSize>
</triggeringPolicy>
</appender>
As you can see only few properties can be injected.
You can go through the below link to setup your custom configuration:
https://dzone.com/articles/configuring-logback-with-spring-boot
https://springframework.guru/using-logback-spring-boot/
No. The easiest way to do that is with an extra xml file.
I'm using logback.xml
<?xml version="1.0" encoding="UTF-8"?>
<property name="DEV_HOME" value="c:/logs" />
<appender name="FILE-AUDIT"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${DEV_HOME}/debug.log</file>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>
%d{yyyy-MM-dd HH:mm:ss} - %msg%n
</Pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>
${DEV_HOME}/debug.%d{yyyy-MM-dd}.%i.log
</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>10MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
</appender>
<logger name="ar.com" level="debug" additivity="false">
<appender-ref ref="FILE-AUDIT" />
</logger>
<root level="error">
<appender-ref ref="FILE-AUDIT" />

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" />
</root>
</configuration>
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="${LOG_PATH}/archive" />
<appender name="Console-Appender" class="ch.qos.logback.core.ConsoleAppender">
<layout>
<pattern>[%d{yyyy-MM-dd HH:mm:ss}] - [%X{requestId}] - %p %c -- %m%n</pattern>
</layout>
</appender>
<appender name="File-Appender" class="ch.qos.logback.core.FileAppender">
<file>${LOG_PATH}/logfile.log</file>
<encoder>
<pattern>[%d{yyyy-MM-dd HH:mm:ss}] - [%X{requestId}] - %p %c -- %m%n
</pattern>
<outputPatternAsHeader>true</outputPatternAsHeader>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>${LOG_ARCHIVE}/rollingfile.log.%d{yyyy-MM-dd}.log
</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>10MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
</appender>
<logger name="coinPay.logbackxml" level="info" additivity="false">
<appender-ref ref="Console-Appender" />
<appender-ref ref="File-Appender" />
</logger>
<!-- To remove extra hibernate logs -->
<logger name="org.hibernate">
<level value="info" />
</logger>
<root>
<appender-ref ref="Console-Appender" />
<appender-ref ref="File-Appender" />
</root>
</configuration>
any help will be appreciated. Thank you in advance :D
You need to specify ch.qos.logback.core.rolling.RollingFileAppender as class for your appender. A FileAppender can not roll.
I believe you're missing the %i parameter, which should be replaced by the rolling file index (i.e. 'mylog.2017-03-13.0.txt', 'mylog.2017-03-13.1.txt', etc.)
In addition, like Uwe Allner, I'm using RollingFileAppender instead of FileAppender.
(I also suggest adding a totalSizeCap to the configuration, in order to control to total size)
Here's my entire appender configuration:
<appender name="SQL_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${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>
In our spring-boot project we are using slf4j for logging purpose. Below are configuration which we have added in application.properties file
logging.file=/opt/logs/my_log.log
logging.level.org.springframework.web=INFO
logging.level.org.hibernate=INFO
logging.level.nl.yestelecom.boss=DEBUG
logging.level.com.github.isrsal.logging.LoggingFilter=DEBUG
It generates only 7 backup files (my_log.log.1, my_log.log.2 ..., my_log.log.7) with each file of size 10.5MB and after that logging is not happening at all.
Is there any way to change this behavior?
We looked into available properties of spring-boot but, didn't find anything. Any suggestion is appreciated.
Spring-Boot only allows limited properties to be configured in its application.properties. See the list here.
The default (out-of-the-box) configuration that Spring-boot uses is defined in base.xml. See base.xml config here which includes this File appender
There are 2 ways to add extra configuration
Add logback-spring.xml
If there is a logback configuration XML with name logback-spring.xml in project's classpath, it is picked up by Spring-Boot on initialization.
Point to config file from application.properties
Within application.properties use following to point to your custom logback XML
logging.config= # Location of the logging configuration file. For instance `classpath:logback.xml` for Logback
Once you add the extra config using any of the above 2 steps, the rollover strategy can be mentioned within that custom XML like this
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true">
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<charset>UTF-8</charset>
<Pattern>%d %-4relative [%thread] %-5level %logger{35} - %msg%n</Pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<encoder>
<pattern>${FILE_LOG_PATTERN}</pattern>
</encoder>
<file>${LOG_FILE}</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>${LOG_FILE}.%i</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>10</maxIndex>
</rollingPolicy>
<triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<MaxFileSize>10MB</MaxFileSize>
</triggeringPolicy>
</appender>
<root level="DEBUG">
<appender-ref ref="CONSOLE" />
<appender-ref ref="FILE"/>
</root>
</configuration>
SFL4J is just wrapper. You need to add extra configuration for logback library:
<configuration>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>logFile.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover -->
<fileNamePattern>logFile.%d{yyyy-MM-dd}.log</fileNamePattern>
<!-- keep 30 days' worth of history capped at 3GB total size -->
<maxHistory>30</maxHistory>
<totalSizeCap>3GB</totalSizeCap>
</rollingPolicy>
<encoder>
<pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>
</encoder>
</appender>
<root level="DEBUG">
<appender-ref ref="FILE" />
</root>
</configuration>
source
In this case we have logs from last 30 days but not bigger than 3GB.
for spring-boot 2.0.0:
logging.file.max-history
logging.file.max-size
...and others
Either look at org.springframework.boot.logging.LoggingSystemProperties or
https://docs.spring.io/spring-boot/docs/2.0.5.RELEASE/reference/html/boot-features-logging.html#boot-features-logging-file-output

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>

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">

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>
