Logger level from Layout class
by gaston sponer 22 Aug '13

22 Aug '13

Hi, Is there any way to get from MyLayout the logger level? I don't want to do this: package com.render;import org.slf4j.LoggerFactory;import ch.qos.logback.classic.Logger;import ch.qos.logback.classic.spi.ILoggingEvent;import ch.qos.logback.core.LayoutBase; import com.render.domain.Employee; public class MyLayout extends LayoutBase<ILoggingEvent>{ String level= ((Logger)LoggerFactory.getLogger("employee")).getLevel().toString();...... This works well but i don't like to instantiate an object just to get a logger level. This is my xml config file: <configuration><logger name="employee" level="debug"/> <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender"> <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder"> <layout class="com.render.MyLayout" > </layout> </encoder> </appender> <root level="off"> <appender-ref ref="CONSOLE" /> </root></configuration> Thanks,Gastón.

DuplicateMessageFilter not using params
by Dave Brosius 22 Aug '13

22 Aug '13

Greetings, I want to use the DuplicateMessageFilter but realized that it only works on the format string, and not the complete message. I want to catch the pathological case where something is truly getting logged over and over again and is the same thing which is really probably an undiscovered bug in the code. Is there any such beast available? I realize that one could create their own RealDuplicateMessageFilter and do the appending there, but that just throws away the appending, and it would need to be redone when you actually go to log, which kind of stinks. Any ideas here? thanks! dave

DBAppender and markers
by Leonardo Souza 21 Aug '13

21 Aug '13

Hi, We have a system with a lot of log statements using markers, this.logger.info(this.marker, "ex fvmo dare lvcem"); We are planning to store the logs in a database using DBAppender but ther marker do not have a column, only appears in the formatted_message field. We will query this database filtering by the markers, a sql like query is not a desirable solution. Anyone has a better idea instead of creating a custom appender? thanks .. -- Leonardo S Souza

dbappender options in logback
by smoity＠free.fr 14 Aug '13

14 Aug '13

Hello, Today, logback is properly configured in database mode (oracle in my case). The tables are filled correctly. My problem, which seems so simple, is that I wish such as logger_name from loggin_event table fields can be customizable from the xml configuration file. Is that possible? Or so I'm forced to make my own DbAppender? Regards

Log Forgery - an ideas?
by kommersz 13 Aug '13

13 Aug '13

Hi Logback people, I am now looking for a logging solution to use in a larger piece of software, which would provide protection against Log Forgery (http://cwe.mitre.org/data/definitions/117.html) even in cases when logging to a text file is configured (log forgery is basically about strings containing linefeeds being passed over to the logging framework - if the srings are manipulated in the right way, the new entries look like if they were "real" log entries)I already had a look at log4j, and talked to some people, but to me it seems that they do not offer, and do not want to offer any sort of protection. So I would like to consider now Logback - and hence the question: is Logback offering any sort of solution, or is any solution planned? Cheers,Gabor

Using configuration file and programatically changing configuration?
by Xavier Outhier 12 Aug '13

12 Aug '13

Hi, the idea is to have to enable the user to change the config from the UI of the web applications (without accessing the server). I would like to know if it is possible to have both a configuration file for LogBack for the default usage of the application and the configuration being modified programatically the fly when investigating issue. How to implement that? On way could be to write on the fly the configuration file when it is set to be reloaded automatically but is there an another way that would pause the reading from the config file and use the API? Thanks, Xavier.

Query reg. symlink to the latest log file
by Rahul Amaram 10 Aug '13

10 Aug '13

Hi, Is it possible to automatically create a link whenever a new file is opened for logging? Elaborating, I am using a filenaming convention based on time. For ex. access.log-2013-09-20 access.log-2013-09-21 access.log-2013-09-22 Now, whenever the new log file is generated, I want a symlink "access.log" pointing to the latest log file. Is this possible using some hook? If I were to implement it by extending an appender, could some pointers be provided on how I could get it done? Regards, Rahul.

SocketAppender and ServerSocketReceiver
by Scott Dudley 09 Aug '13

09 Aug '13

I'm attempting to update my logback configuration to support client connections to my main logger via separate, command-line JVM's using another configuration file. I'm having only limited success. My biggest problem currently is that the client connections often write no more than the first log entry to the server. Would very much appreciate some help. My server's logback.xml is as follows: <configuration scan="true" scanPeriod="30 seconds"> <statusListener class="ch.qos.logback.core.status.OnConsoleStatusListener" /> <conversionRule conversionWord="appName" converterClass="com.telesoft.web.LogbackJNDIContextConverter" /> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${catalina.home}/logs/debug.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <fileNamePattern>${catalina.home}/logs/debug%i.log</fileNamePattern> <minIndex>1</minIndex> <maxIndex>5</maxIndex> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <maxFileSize>15MB</maxFileSize> </triggeringPolicy> <encoder> <pattern>%d{MM/dd HH:mm:ss.SSS}|%thread|%X{sessionUserName}|%-5level|%X{debugLevel}|%logger|%replace(%msg%n%ex){'[\n\r]+', '~~~'}|%appName{}%n%nopex</pattern> </encoder> </appender> <root level="DEBUG"> <appender-ref ref="FILE" /> </root> <if condition='isNull("SERVERSOCKETRECEIVERRUNNING")'> <then> <receiver class="ch.qos.logback.classic.net.server.ServerSocketReceiver"> <port>3636</port> </receiver> </then> </if> </configuration> And the client xml thus: <configuration> <appender name="SOCKET" class="ch.qos.logback.classic.net.SocketAppender"> <remoteHost>127.0.0.1</remoteHost> <port>3636</port> </appender> <root level="ERROR"> <appender-ref ref="SOCKET" /> </root> </configuration> -- Scott Dudley | Senior Developer Telesoft | 1661 E.
