DuplicateMessageFilter : time based duplication
by Nicolas G 13 Nov '13

13 Nov '13

Hi, We are using a modified version of ch.qos.logback.classic.turbo.DuplicateMessageFilter in our project. We replaced the LRUMessageCache with a cache with a time based eviction. This new cache is build with guava CacheBuilder. The goal is to avoid duplicate messages during a time frame. I joined the class as it may be useful to other Thanks Nicolas

SimpleServerSocket
by José Laredo López 08 Nov '13

08 Nov '13

Hi, I'm trying to connect to a SimpleServerSocket like the example in the documentation with a SocketAppender. If I send messages continuosly, the server don't receive the messages. If the client programs sends the messages with a sleep, the server receives the message correctly. Can you help me?. This is the code and the configuration file: Client program: /* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package logbackc; import java.util.ArrayList; import java.util.Date; import java.util.Random; import java.util.logging.Level; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class LogBackC { /** * @param args the command line arguments */ public static void main(String[] args) throws InterruptedException { Logger logger = LoggerFactory.getLogger("ABCDEF"); Integer th = 1; Integer pe = 100; Random r = new Random(); for (int i = 0; i < pe; i++) { Integer num = r.nextInt(10); Boolean war = r.nextBoolean(); String message= "ABCDEF-" + (war ? "W" : "E") +"-"+ num; logger.info("{} {} {}",message, th, i); } } } Client config file: <?xml version="1.0" encoding="UTF-8"?> <configuration> <property name="HOSTNAME" value="127.0.0.1" /> <property name="PORT" value="6000" /> <appender name="SOCKET" class="ch.qos.logback.classic.net.SocketAppender"> <remoteHost>${HOSTNAME}</remoteHost> <port>${PORT}</port> <reconnectionDelay>10000</reconnectionDelay> <includeCallerData>false</includeCallerData> </appender> <root level="INFO"> <appender-ref ref="SOCKET" /> </root> </configuration> Server config file: <?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="FILE" class="ch.qos.logback.core.FileAppender"> <file>testFile.log</file> <append>true</append> <encoder> <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern> </encoder> </appender> <root level="DEBUG"> <appender-ref ref="FILE" /> </root> </configuration> Thank you very much

How to handle logging in aop methods
by Mandy Warren 01 Nov '13

01 Nov '13

Hi, I am using AOP to log exceptions from methods after they are thrown. I have an Aspect which does the following:- @AfterThrowing(pointcut = "execution(* *(..))", throwing = "ex") public void logExceptions "(JoinPoint jp, Throwable ex) { Logger exceptionLogger = LoggerFactory.getLogger(jp.getStaticPart().getSignature().getDeclaringTypeName()); exceptionLogger.error(ex.getMessage(), ex); } Now, my logback config is set to log the method and line number as follows:- %class$%M:%L$ This works great for classes which don't use the aspect but for the classes which throw the exception I get the method logged as "logExceptions" (ie. the method in the Aspect) and the line number of the line where the exceptionLogger.error is called. What I really want to log is the calling class and the method which threw the exception. So I used %logger% instead of %class% which worked great (it gave me the calling class) BUT I can't see a way to get the method from the logger (I can get it via the AOP joinpoint but that doesn't help!). Is it possible? I also tried using %caller{2} which did work (although the line number wasn't accurate) but I'd like to remove the Caller+0 part and reformat the Caller+1 line to look the same as the output from %class$%M:%L$ - not sure if this is possible or whether there is a simpler way to achieve what I want Any advice much appreciated! Many thanks Mandy Sent from a mobile device

Any way to use all syslog level with syslog appender?
by Erik Steffl 31 Oct '13

31 Oct '13

Is there any way to use all syslog levels (see e.g. http://en.wikipedia.org/wiki/Syslog#Severity_levels) when using Syslog appender? I see the constants for them defined in: https://github.com/qos-ch/logback/blob/master/logback-core/src/main/java/ch… but I don't see all of them used. Thanks, erik

getting a null logger level
by gaston sponer 30 Oct '13

30 Oct '13

I'm getting a null logger level when I change the level of the logger from Logback.xml: Logger logger = (Logger) LoggerFactory.getLogger(event.getLoggerName()); logger.getLevel(); ----> getLevel == null. First time i run my app logger.getLevel() I get a successful "INFO" Logback.xml: <logger name="com.HomePageAction" level="INFO" /> but when i change it to "debug" and redeploy my app, logger.level is null. Logback.xml: <logger name="com.HomePageAction" level="DEBUG" /> Any idea what could be wrong here ? Thanks

Setting the log file file size with RollingFileAdapter does not work
by adriana lima 30 Oct '13

30 Oct '13

Hello everyone, I am trying to specify the size of my log file in my Java code. However, no file is written in the specified directory. Using a FileAppender without a triggering policy works fine. But I would like to specify the max. log file size. Any help is appreciated :) Thanx in advance! Here is my code: LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory(); RollingFileAppender<ILoggingEvent> fileAppender = new RollingFileAppender<ILoggingEvent>(); fileAppender.setContext(loggerContext); fileAppender.setFile("C:\\log\\log.txt"); SizeBasedTriggeringPolicy<ILoggingEvent> triggeringPolicy = new SizeBasedTriggeringPolicy<ILoggingEvent>(); triggeringPolicy.setMaxFileSize("5MB"); triggeringPolicy.start(); PatternLayoutEncoder encoder = new PatternLayoutEncoder(); encoder.setContext(loggerContext); encoder.setPattern("%d %level %logger: %msg%n"); encoder.start(); fileAppender.setEncoder(encoder); fileAppender.setTriggeringPolicy(triggeringPolicy); fileAppender.start(); Logger logbackLogger = loggerContext.getLogger("ExportMapToFile"); ((ch.qos.logback.classic.Logger) logbackLogger).addAppender(fileAppender); logbackLogger.info(info); fileAppender.stop(); triggeringPolicy.stop(); encoder.stop();

Logs are written in wrong file when changing log level.
by Harsimranjit singh Kler 29 Oct '13

29 Oct '13

Hi I am using slf4j 1.7.5,logback 1.0.3. In my app i am using application context to set app name as per given example. http://logback.qos.ch/faq.html Is it possible for multiple JEE applications to share the same configuration file but without stepping on each other's toes?<http://logback.qos.ch/faq.html#sharedConfiguration> Every thing is fine intially and one common xml file is writing in different log files but when i am changing log level its not reading applicationName and start writing in "application-name_IS_UNDEFINED1.log" File. Why this behaviour?
