I have my current logback file, which to my understanding is a classic logback implementation:
<configuration debug="true">
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>Hello %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="STDOUT" />
</root>
</configuration>
I have a specific log:
log.info(String.format("ProxyICA %s has an integrity violation. %s.",
processorId.getProxyIca(),
fkViolationMsg)
);
that I am trying to get in a text file. The only configuration I need in my logback is to put every instance of this log into a text file. Every other log can default log to the console (which it was doing without the logback.xml).
Thank you in advanced!
Here is an example of setting it up log to a specific file "Custom-Errors.txt", and to have the logs be deleted if they reach a certain size 20MB or 182 days elapse
<appender name="Custom_Logger
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>Custom-Errors.txt</file>
<rollingPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<fileNamePattern>Custom-Errors-%d{yyyy-MM-dd}.%i.txt</fileNamePattern>
<!-- each file should be at most 20MB, keep 182 days worth of history,but
at most 500MB -->
<maxFileSize>20MB</maxFileSize>
<maxHistory>182</maxHistory>
<totalSizeCap>500MB</totalSizeCap>
</rollingPolicy>
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>INFO, DEBUG, TRACE</level>
</filter>
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>
%date %level [%thread] [%file:%line] %msg%n%throwable
</Pattern>
</layout>
</appender>
<logger name="CUSTOM_LOGGER" additivity="false">
<appender-ref ref="Custom_Logger" />
</logger>
Then in your java class make a private variable to use the logger like this
private static final Logger CUSTOM_LOGGER =
LoggerFactory.getLogger("CUSTOM_LOGGER");
logging a dependency, or use to log anything you want based on package
here is an example of logging a library
<appender name="ConsoleOutForSpring" class="ch.qos.logback.core.ConsoleAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>INFO</level>
</filter>
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>
%black(%d{ISO8601}) %highlight(%-5level) [%blue(%t)] %yellow(%C{1.}): %msg%n%throwable
</Pattern>
</layout>
</appender>
<logger name="org.springframework" additivity="false">
<appender-ref ref="ConsoleOutForSpring" />
</logger>
I do admit there are a lot of tags and settings to this logger that are kind of complicated, but reading docs and looking at others examples has helped me.
Here were some docs I noted in my logback.xml
<!-- http://logback.qos.ch/manual/configuration.html this helped me with this weird looking stuff i.e. ===> %date %level [%thread] [%file:%line] %msg%n%throwable -->
<!-- http://logback.qos.ch/manual/appenders.html#SizeAndTimeBasedRollingPolicy
helped me set this up:
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<fileNamePattern>Errors-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
<maxFileSize>20MB</maxFileSize>
<maxHistory>182</maxHistory>
<totalSizeCap>500MB</totalSizeCap>
</rollingPolicy>

I have a spring boot app(spring-boot-starter-parent --> 2.3.0.RELEASE) that I am implementing log.
Basically what I am trying to achieve is that I have 2 log files one bridgeError.log which contains only error messages and bridge.log which will contain all log level except Error level since it is being logged in brideError.log file.
I am able to create 2 logs file brideError.log which contains only error messages but the issue is that
bridge.log also contains error messages.
Please find my logback-spring.xml configuration below:

Is it possible to exclude error messages in bridge.log file?
Thanks in advance
You can use a level filter for that purpose
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>ERROR</level>
<onMatch>DENY</onMatch>
<onMismatch>ACCEPT</onMismatch>
</filter>
Docs: http://logback.qos.ch/manual/filters.html
I need a little help, I'm developing a bot in my java telegram and I thought to insert slf4j as a loggin system, so you can manage the log through a server-side xml file, I wanted to print the log on the file, only since that moment it seems that the loggin system is not managed anymore by the xml file also because I only print the ERROR level logs even if I inject the debug level.
Another note that I think is relevant and that on the server I get a SEVERE type error and I do not type you ERROR so from here I have deduced that the logger is managed differently, how can I solve it?
I'll post my logback.xml file

I am new to coding and stackoverflow, We are using logback for logging our application, as of now we are using {fileName}.%d{yyyy-MM-dd}.log naming convention for the time based rolling policy (rolling take place each and every day) and have set 30 days as the maximum time for a log to be stored in the application. We need to change the naming convention to only date format ({fileName}.%d{dd}.log). But we are getting "The date format in fileNamePattern will result in collisions in the names of archived log files." error
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>
%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n

<appender name="dailyRollingFileAppender"

<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>
%d{HH:mm:ss.SSS} [%thread] %-5level %logger{35} - %msg %n
</Pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>logs/deliveryService.%d{yyyy-MM-dd}.log
</fileNamePattern>
<!-- Delete log after 30 days -->
<maxHistory>30</maxHistory>
</rollingPolicy>
</appender>
<!-- Send logs to both console and file audit -->
<logger name="com.bnsf" level="debug"
additivity="false">

Because in a month like February, with only 28/29 days, in a 30-day windows you will have deliveryService.01.log and deliveryService.02.log files twice.
I support a solution that is using logback to generate logfiles. The issue is that the generated logfiles are created so fast that they are filling up the hard drive and causing the system to crash.
When analyzing the created logfiles we can see that they are 5MB in size and when they roll over the next logfile is the same data from the previous one with only 15-20 trace lines added, then it will create the next one in the same format and continue at a fast rate. Has anyone ever seen this behavior using logback? The issue is with the esuiteStore* logs:
${esStoreLogFilePath}/esuiteStore-%d{yyyy-MM-dd}.%i.log
This is not seen in our other customers and we have not been able to recreate it in our test environment (using the same SW and logback.xml). On my system the logfiles are created correctly (the same logging is not copied into the next rollover file). My understanding is that it should be creating 5MB rollover logfiles, and save four days worth of logging.
I am not exactly sure what version of logback I am using but I found the following in the c:\java directory.
Manifest.mf in logback-classic-0.9.26.jar file Build-Jdk: 1.6.0_16
Java(TM) 6 Update 13 6.0.130 is installed.

The issue was that there were multiple processes running trying to access the logfile so once it tried to rollover it started creating multiple logfiles with the same data. The process list showed multiple instances of Java running.
I have the following logback.xml file:
<configuration>
<!--Daily rolling file appender -->
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>/usr/share/tomcat6/logs/api.log</File>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<FileNamePattern>/usr/share/tomcat6/logs/api/api.%d{yyyy-MM-dd}.gz</FileNamePattern>
</rollingPolicy>
<encoder>
<pattern>%date %level [%thread] %logger{10} [%file:%line] %msg%n</pattern>
</encoder>
</appender>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="FILE" />
<appender-ref ref="STDOUT" />
</root>
</configuration>
My log file is working just fine. The folling file aspect however is not. Instead of gzipping the file and moving it into the api folder, it is putting it in the same directory and renaming it to
api.log(string of numbers).tmp
e.g.
api.log849916939395200.tmp
Does anyone know why this is happening?
Just remove the file tag from appender. Use something like this,
<appender name="contentDeliveryLogAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover -->
<fileNamePattern>${ICEX_HOME}/logs/content-delivery.%d{yyyy-MM-dd}.log</fileNamePattern>
<!-- keep 1 days' worth of history -->
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%d [%thread] %-5level %logger{36} H:${HOSTNAME} - SC:%X{optionalParam} %msg%n</pattern>
</encoder>
</appender>
This is working for me as recommended by documentation of logback here
I had the similar issue. To fix this issue change the pattern to
/usr/share/tomcat6/logs/api/api.%d{yyyy-MM-dd}.%i.gz.
You missed the %i in the end.
