Doubt about multiple configurations
by Vitor Granzinoli Vellozo 31 May '11

31 May '11

Hi Logbackers, In my application, I need multiple configurations to generate multiple files. The first problem is, I have to use one logback configuration with no modifications (because we have to use a proprietary framework, it is a framework of our client), so I have to keep a main configuration. The second problem is, the business of my application needs more than 3 different logs, so I need at list one more Logback configuration where I can put more than one file appender. My question is: How can I have one more logback configuration that do not have any application dependencies. That can be read from a "Helper/Util" class without any help from the infrastruture (ex: Spring). Or, if anyone have another idea? Thanks a lot! Vitor

multiple apps deployed in Tomcat
by Nathaniel Auvil 30 May '11

30 May '11

I want to deploy multiple applications in Tomcat. Each one will include Logback jars. I need to have the log configuration file external to the war so i can change them on the fly. Is the "best" way to do this to have an init servlet in each application which loads from the filesystem? I can pass a system property on Tomcat startup which points to a "config" directory.

how to disable logback from logging system properties?
by Bryan Ward 27 May '11

27 May '11

Hello, I'm using the DBAppender and the MDC to log certain elements of the requests into our application. I've noticed that besides just the elements that I've put in the MDC, all of the system properties are also being logged to the logging_event_property table. This has caused many concerns because there are certain system properties that should not be logged. Here is my DB Appender configuration <appender name="DB" class="ch.qos.logback.classic.db.DBAppender"> <connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource"> <dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource"> <driverClass>${db.jdbc.driverClassName}</driverClass> <jdbcUrl>${db.jdbc.url}</jdbcUrl> <user>${db.jdbc.username}</user> <password>${db.jdbc.password}</password> </dataSource> </connectionSource> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %X %ex{short} - %n</pattern> </encoder> </appender> Note that the properties for username / password / etc are pulled in from another file using the <property file="_path_to_file/conf.properties" /> All the properties in the external file are being logged which contain passwords etc that do not belong in the logging_event_property table. I've searched through the manual and the documentation but cannot find a way to disable this behaviour. Any help would be most appreciated! Cheers, Bryan

LogBack JNDIConnectionSource
by Alphy 27 May '11

27 May '11

I am using JNDIConnectionSource for writing logs to my postgres DB .But I am facing a problem in transaction handling . App Server : Glassfish. In EJB , I have Stateteless Session Bean and I have private static final Logger auditlog = LoggerFactory.getLogger("audit"); Inside I have method for transactions. Bean{ Method(){ Method1(); Method2(); auditlog.info("method"); } Method1() { em.persist(); auditlog.info("method1"); } Method2() { em.persist(); auditlog.info("method2"); } } <appender name="DB" class="ch.qos.logback.classic.db.DBAppender"> <connectionSource class="ch.qos.logback.core.db.JNDIConnectionSource"> </connectionSource> </appender> I wanted Method1 and Method 2 in one transaction and if any failure need to rollback both. Earlier when I was writing logs to file it was working fine and now when I changed to Db, I realised the call to write logs is closing existing transaction and starting new transaction to write to DB. Please let me know how I can use the same transaction for writing to logs. I am using same connection pool for both logging and application. -- View this message in context: http://old.nabble.com/LogBack--JNDIConnectionSource-tp31704423p31704423.html Sent from the Logback User mailing list archive at Nabble.com.

Logging messages from org.apache.xml.security.utils.DigesterOutputStream.class
by Swapna Gupta 26 May '11

26 May '11

I am thoroughly confused by the different logging facades. I am trying to get debug messages from org.apache.xml.security.utils.DigesterOutputStream.class which is being called by opensaml apis. OpenSaml uses SLF4J. I am not sure what needs to be in my classpath and what shouldn't be there. I added the logback classic and logback core and jcl-over-slf4j. I don't see any messages. If I put following line in my code: org.apache.commons.logging.Log log = LogFactory.getLog(org.apache.xml.security.utils.DigesterOutputStream.class); I find that the log object contains a logger which is an instance of org.slf4j.helpers.NOPLogger(NOP). Can you please help me to get the set up right? Thanks.

Rolling not working?
by Eric Pederson 26 May '11

26 May '11

Dear all: I have the following configuration: String filename = "notification" appender("FILE", RollingFileAppender) { file = (jbossHomeDir ? jbossHomeDir + "/" : "") + "log/" + filename + ".log" rollingPolicy(TimeBasedRollingPolicy) { fileNamePattern = filename + ".%d{yyyy-MM-dd_HH-mm}.log" maxHistory = 30 } encoder(PatternLayoutEncoder) { pattern = logPattern } } I have it set to roll every minute just for testing. It appears that logback is recognizing my configuration correctly: 08:55:56,095 |-INFO in ch.qos.logback.classic.gaffer.ConfigurationDelegate@2d7d1491 - About to instantiate appender of type [ch.qos.logback.core.rolling.RollingFileAppender] 08:55:56,095 |-INFO in ch.qos.logback.classic.gaffer.ConfigurationDelegate@2d7d1491 - Naming appender as [FILE] 08:55:56,111 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - No compression will be used 08:55:56,112 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Will use the pattern notification.%d{yyyy-MM-dd_HH-mm}.log for the active file 08:55:56,117 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - The date pattern is 'yyyy-MM-dd_HH-mm' from file name pattern 'notification.%d{yyyy-MM-dd_HH-mm}.log'. 08:55:56,117 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Roll-over every minute. 08:55:56,117 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Setting initial period to Thu May 26 08:55:27 EDT 2011 However, no rolling is happening. Ideas? Thanks, -- Eric

Any update on when we can expect logback 0.9.29? There seem to be a number of fixes available but in particular http://jira.qos.ch/browse/LBCLASSIC-246 is really causing us a lot of grief... -Tommy
