Setting log levels per context
by Daniel López 14 May '13

14 May '13

Hi there, I have been able to separate the different logs of differents web applications in a shared host using a sift appender like this one: <appender name="SIFT" class="ch.qos.logback.classic.sift.SiftingAppender"> <discriminator class="ch.qos.logback.classic.sift.JNDIBasedContextDiscriminator"> <defaultValue>unknown</defaultValue> </discriminator> <sift> <appender name="FILE-${contextName}" class="ch.qos.logback.core.FileAppender"> <file>${catalina.base}/logs/logback-${contextName}.log</file> <append>true</append> ... </appender> </sift> </appender> And so far, it works great. My question now would be if it is possible to set different levels for the different contexts in an easy way. I know I can copy the library on each application and use a different configuration file per webapp (not using logback for the global Tomcat then) and I have been able to use Filter to simulate the level setting per context by setting the level to the Max and then filtering out the levels by context... but I was wondering if there is no easier way to do it, as adding filter code for each webapp makes the configuration look fragile and bloated. I have 28 small-medium apps in this host, so that's why I'm trying to find the simplest way :). So I guess I'm looking for something like.. <logger name="org.whatever" level="INFO" context="MyApp"...> Does something like that exist and I was unable to find it? If no, do you think it would be intesting? I might give it it shot if that's the case. Cheers!

SMTPAppender with Amazon SES
by Jason Bennett 14 May '13

14 May '13

I'm using Amazon SES with SSL to send emails via Logback's SMTPAppender. It usually works, but sometimes I receive the following error: 0:01:51,863 |-ERROR in ch.qos.logback.classic.net.SMTPAppender[EMAIL] - Error occurred while sending e-mail notification. com.sun.mail.smtp.SMTPSendFailedException: 554 Transaction failed: Illegal header 'Caused by'. at com.sun.mail.smtp.SMTPSendFailedException: 554 Transaction failed: Illegal header 'Caused by'. at at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:2114) at at com.sun.mail.smtp.SMTPTransport.finishData(SMTPTransport.java:1900) at at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:1122) at at javax.mail.Transport.send0(Transport.java:195) at at javax.mail.Transport.send(Transport.java:124) at at ch.qos.logback.core.net.SMTPAppenderBase.sendBuffer(SMTPAppenderBase.java:395) at at ch.qos.logback.core.net.SMTPAppenderBase$SenderRunnable.run(SMTPAppenderBase.java:690) at at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1146) at at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at at java.lang.Thread.run(Thread.java:679) I'm aware that Amazon only allows emails with legal headers through SES, but I have no idea where Amazon is getting this header from. Has anyone else seen this? jason -- Jason Bennett, jasonab(a)acm.org E pur si muove! Get Firefox! - http://getfirefox.com

Fwd: Time based rolling on Android
by Jonas Schmid 13 May '13

13 May '13

Hi there, I am trying to use the time based rolling configuration for my android app. I got my configuration from the doc ( http://logback.qos.ch/manual/appenders.html#TimeBasedRollingPolicy) but it does not seem to work on my app. Please find enclosed my config file. The file does not roll and everything goes to log.log. To try it out I changed the date on my phone. I took care of killing the app before doing so. I also set the time to 23h59 then launched my app and waited, but it did not work either. What did I do wrong? Thanks Jonas

CONTEXT_NAME property with DBAppender
by Xavier Dury 08 May '13

08 May '13

Hi, I'm using a DBAppender and when I log something, I see that a LOG_EVENT_PROPERTY row with MAPPED_KEY = 'HOSTNAME' is inserted with the LOG_EVENT. Is there an option (in configuration) to make the CONTEXT_NAME visible too in the same way when using a ContextSelector or do I have to put it myself in the MDC through a Servlet Filter? Regards, Xavier

default delimiter for MDC?
by Yoni Moses 06 May '13

06 May '13

Hi, I've been trying to use the new feature of the MDC without any luck.. it's probably a silly question, but can someone please post exact format for it? I've tried it without any luck... from what I've seen in the examples it seems like %X{req.xForwardedFor:-NONE} should work.. but for me it keeps on saying: ScanException: Expecting } under Parser.expectCurlyRight version is 1.0.12 with slf4j 1.7.5 Help is much appreciated ;) -- Cheers, Yoni

logback config scan doesn't detect changes in included files
by Richard Sand 05 May '13

05 May '13

Hi all – I’m wondering if this is expected behavior. I’ve a web application war file with a minimal logback.xml file in its WEB-INF/classes folder, which then uses a JNDI env variable to pull in a config file that is external to the application. This greatly facilitates deployment because I can override the env variable when I deploy the war (e.g. in Tomcat, a context.xml file) and specify the external location of the file, allowing me to deploy the war unchanged on different platforms and environments. But… I was hoping that having “scan=true” in the logback.xml file would allow me to alter the runtime logback configuration without restarting the context, but it doesn’t seem to be working. My logback.xml file: <configuration scan="true"> <insertFromJNDI env-entry-name="java:comp/env/appHome" as="appHome" /> <include file="${appHome}/conf/logback-app.xml"/> <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator"/> </configuration> Is this a bug or a known/accepted limitation of using scan=true?

Trouble with setup logback to Oracle DB
by Horia Balog 03 May '13

03 May '13

Hi - need some help figuring out how to properly setup logback config to Oracle DB. I've managed to get it to work, but only getting the records in the DB when closing the logger. I am actually using logback through the Metrics library ( metrics.codahale.com) so using the logger through a metrics reporter object. But the end result is I can see the records (test records for now!) in the DB only at the end of the test when I stop the metrics reporter. Assuming this might be related to the config I'm using: <appender name="DatabaseAppender" class="ch.qos.logback.classic.db.DBAppender"> <connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource"> <driverClass>oracle.jdbc.OracleDriver</driverClass> <url>jdbc:oracle:thin:@192.168.1.1:1521:XE</url> <user>abcde</user> <password>abcde</password> </connectionSource> </appender> Is there a way for me to change the config so each record inserted is committed right away? Thanks, Horia
