My requirement is to print logs in current date directory and logs needs to be rollover in current date directory with below conditions :
Either hit max file size
Or date has changed
So today date is 16/07/2019 so directory structure should be
16_07_2019/fde.log (current log)
16_07_2019/fde.1.log (due to max size)
16_07_2019/fde.2.log (due to max size)
15_07_2019/fde.log (yesterday log)
15_07_2019/fde.1.log (yesterday log due to max size)
my logback.xml is :
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true">
<include resource="org/springframework/boot/logging/logback/defaults.xml"/>
<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>/VVV/AA/%d{yyyy_MM_dd}/fde.log</file>
<rollingPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>/VVV/AA/%d{yyyy_MM_dd}/fde.%i.log
</fileNamePattern>
<maxFileSize>2MB</maxFileSize>
</rollingPolicy>
<encoder>
<pattern>%d{MM:dd HH:mm:ss.SSS} [%t] [%level] [%logger{36}] - %msg%n
</pattern>
</encoder>
</appender>
<root level="DEBUG">
<appender-ref ref="FILE"/>
</root>
</configuration>
Instead of creating current date directory it is create %d{yyyy_MM_dd} directory. I am not sure why?
Also, Is this xml looks fine based on my requirement?
Using SpringBoot : 2.0.5 version
Try this:
<file>/VVV/AA/logs/fde.log</file>
<rollingPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>/VVV/AA/logs/fde-%d{yyyy_MM_dd}.%i.log</fileNamePattern>
<maxFileSize>2MB</maxFileSize>
</rollingPolicy>
As in roll only over the file name rather than log file directory.
First of all, I don't like this solution... but it works...
Declare a "timestamp" property before starting Spring Boot.
public static void main(String[] args) {
System.setProperty("timestamp", Constants.ISO_YYYY_MM_DD_FORMAT.format(System.currentTimeMillis()));
SpringApplication app = new SpringApplication(MainConfig.class);
app.setBannerMode(Banner.Mode.OFF);
app.run(args);
}
In application.properties
logging.path=${folder.deploy}/logs/${timestamp}
In logback.xml, you import the property
<springProperty scope="context" name="LOG_PATH" source="logging.path" />
And off you go...
I still think there has to be an application.properties ONLY solution...

I wrote a TimeBasedRollingPolicy logback.xml, and while the log file is created succesfully, it seems to be reading it from the application.properties instead. Here is my setup:
logback.xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<include resource="org/springframework/boot/logging/logback/defaults.xml"/>
<include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
<appender name="ROLLING-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.TimeBasedRollingPolicy">
<!-- daily rollover -->
<fileNamePattern>${LOG_FILE}-%d{yyyy-MM-dd}.log</fileNamePattern>
</rollingPolicy>
</appender>
<root level="INFO">
<appender-ref ref="CONSOLE"/>
<appender-ref ref="ROLLING-FILE"/>
</root>
</configuration>
application.properties
logging.path=/path/to/log/folder/
logging.file=${logging.path}myLog
logging.pattern.file=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
When I run my application, the log is successfully saved in the correct path, but only as myLog. I would want it to be appended with the date (as in the logback.xml). Note I do want to keep taking the logging.path and logging.file from the application.properties because I have multiple depending on the environment.
Thanks
1) You need to set a logging.file or logging.path property, not both.
So logging.file=/path/to/log/folder/myLog should be enough to get a myLog log file in the specified path.
The spring boot documentation mentions that.
2) This is the format pattern for the log rolling, not for the current log :
<fileNamePattern>${LOG_FILE}-%d{yyyy-MM-dd}.log</fileNamePattern>
You get this format automatically for the current log file when it is rolled/archived because the time limit defined by the pattern is reached. In your case, it means everyday.
I have the following logback.xml file for my spring boot application where I intend to create daily log files:
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true">
<appender name="rollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover -->
<fileNamePattern>./logs/my-log-file.%d{yyyy-MM-dd}.log</fileNamePattern>
<maxHistory>15</maxHistory>
<totalSizeCap>15MB</totalSizeCap>
</rollingPolicy>
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>%d [%-5thread] [%-1p] [%logger{35}] - %msg%n</Pattern>
</layout>
</appender>
<root level="WARN">
<appender-ref ref="rollingFile"/>
</root>
<root level="INFO">
<appender-ref ref="rollingFile"/>
</root>
</configuration>
The files are created like this:
my-log-file.2018-11-10.log
my-log-file.2018-11-11.log
my-log-file.2018-11-12.log
I am looking to have the current active log file without the date so it is generic name like my-log-file.log and only when the date rolls to a new day, the file is renamed with date.
What change is required on the logback.xml to enable this configuration?
Add a <file> to the <appender>, like so:
<appender name="rollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>./logs/my-log-file.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover -->
<fileNamePattern>./logs/my-log-file.%d{yyyy-MM-dd}.log</fileNamePattern>
<maxHistory>15</maxHistory>
<totalSizeCap>15MB</totalSizeCap>
</rollingPolicy>
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>%d [%-5thread] [%-1p] [%logger{35}] - %msg%n</Pattern>
</layout>
</appender>
From the Logback documentation:
Note that the file property in RollingFileAppender (the parent of
TimeBasedRollingPolicy) can be either set or omitted. By setting the
file property of the containing FileAppender, you can decouple the
location of the active log file and the location of the archived log
files. The current logs will be always targeted at the file specified
by the file property. It follows that the name of the currently active
log file will not change over time. However, if you choose to omit the
file property, then the active file will be computed anew for each
period based on the value of fileNamePattern.
In my application-properteis, i have set spring.profiles.active=dev, but when i pass from command line via gradle clean -Dspring.profiles.active=stg build, it is taking by default dev profile only. how ot overwrite the default value set in application.properteis.
You can use below configuration using profile. Active profiles can be set using command line argument -Dspring.profiles.active="abc". For multiple profiles, you can include profile names comma separated.
<?xml version="1.0" encoding="UTF-8"?>
<appender name="rootappender" class="ch.qos.logback.core.rolling.RollingFileAppender">
<springProfile name="abc">
<file>${LOG_ROOT}/abc.log</file>
</springProfile>
<springProfile name="xyz">
<file>${LOG_ROOT}/xyz.log</file>
</springProfile>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover. Make sure the path matches the one in the file element
or else the rollover logs are placed in the working directory. -->
<fileNamePattern>${LOG_ROOT}/system_%d{yyyy-MM-dd}.log</fileNamePattern>
</rollingPolicy>
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>10MB</maxFileSize>
</triggeringPolicy>
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>

I am Configured Logger For my application And Give the Logfilename as Current Time Stamp So It Expected to create one log File with the name as current Time stamp BuT INSTEDE IT CREATE ONE LOGFILE WITH CURRENT TIMESTAMP AND ANOTHER FILE WHICH IS BLANK CANT FIGURE OUT WHY IT CREATING EXTRA FILE??
I am using Logback logger in my application and Here is my logback.xml looks like My application is simple core java application. where i user logger to log the statements
<?xml version="1.0" encoding="UTF-8"?>
<configuration>`enter code here`
<timestamp key="byDay" datePattern="yyyy'-'MM'-'dd'''AT'''HH'-'mm'-'ss"/>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file> Myapplication${byDay}.txt </file>
<append>FALSE</append>
<encoder>
<pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>
</encoder>
</appender>
<root level="DEBUG">
<appender-ref ref="FILE" />
</root>
</configuration>
I'm working on a project where I thought I would try using logback-classic for debugging and log rotation. I'm using this in a Maven context for building and creating a .war file to be deployed in JBoss 7.1 Application Server.
I've placed a logback.xml file in the resources folder in the code and a logback-test.xml in test/resources.
The active jar I'm using is the SLF4J to print the actual debugging.
public class MyClass extends MultiActionController {
private Logger logger = LoggerFactory.getLogger(MyClass.class);
public MyClass() {
logger.debug("hello");
}
}
When I run a JUnit test on the code in Maven itself it works, but after building a .war file i don't get any debugging in STDOUT nor can I find a file created.
I know that I've removed the actual logging from STDOUT in the config file, but where is the logging going...
the logback.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>DEBUG</level>
</filter>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<FileNamePattern>logs/myproject.%d{yyyy-MM-dd}.log</FileNamePattern>
<MaxHistory>30</MaxHistory>
</rollingPolicy>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>%d{yyMMdd HH:mm:ss.SSS} [%-5.5level] [%-25.25logger] %msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="FILE" />
</root>
</configuration>
The folder "logs" do I need to explicit create it in the JBoss instance or need to refer relative to it for this to work? Or is there something I missed? Do I need to put the logback.xml file in the JBoss instance?
best,
Henrik
Firstly you should ensure that the logback.xml is at the classpath, e.g. WEB-INF/classes/logback.xml as the mentioning at Chapter 3: Logback configuration.
The Chapter 4: Appenders mentions about FileAppender and RollingFileAppender properties as
file *String* The name of the file to write to. If the file does not exist, it is created. On the MS Windows platform users frequently forget to escape back slashes. For example, the value c:\temp\test.log is not likely to be interpreted properly as '\t' is an escape sequence interpreted as a single tab character (\u0009). Correct values can be specified as c:/temp/test.log or alternatively as c:\temp\test.log. The File option has no default value.
If the parent directory of the file does not exist, FileAppender will automatically create it, including any necessary but nonexistent parent directories.
The example is for logback.xml is as the following:-
<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 -->
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>
</encoder>
</appender>
<root level="DEBUG">
<appender-ref ref="FILE" />
</root>
</configuration>
I hope this may help.
You need to define the file-tag (as the previous answers already said). But you also need to know how it's interpreted. Logback sees it as relative to the application it's used in. So if you only use
<file>logs/<myfile>.log</file>
logback should create a "logs"-folder in the root of your JBoss (more specific: the folder where the .sh-script you start it with is located). Check from the root of your JBoss to see if you can find your logs-folder and file from there.
