I'm trying to get json logs from Nexus 3. Since it use logback, I tried ton change the logback.xml file but, for some reason, it result to no logs at all... Does someone know what I did wrong?
The only things I changed is to add those lines to the Nexus's default logback.xml file, to add json logs:
<appender name="json" class="ch.qos.logback.core.ConsoleAppender">
<filter class="org.sonatype.nexus.pax.logging.NexusLogFilter" />
<layout class="ch.qos.logback.contrib.json.classic.JsonLayout">
<jsonFormatter class="ch.qos.logback.contrib.jackson.JacksonJsonFormatter">
<prettyPrint>true</prettyPrint>
</jsonFormatter>
<timestampFormat>yyyy-MM-dd' 'HH:mm:ss.SSS</timestampFormat>
</layout>
</appender>
and change these for logback to actually use it:
<root level="${root.level:-INFO}">
<appender-ref ref="osgi"/>
<appender-ref ref="console"/>
<appender-ref ref="json"/>
<appender-ref ref="logfile"/>
<appender-ref ref="clusterlogfile"/>
<appender-ref ref="tasklogfile"/>
<appender-ref ref="metrics"/>
</root>

I'm currently formatting my logs in logback like below. However, when I run my app locally I don't want all this metadata gunking up my logs, I just wanna see the message. How can I say "If an environment variable = 'local' then format this way, else format as below"?
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<Target>System.out</Target>
<encoder>
<Pattern>
date=%d{yyyy-MM-dd HH:mm:ss} | rte=${RTEID} | runId=%X{RunId} | interface=%X{Interface} | class=%class{0}.%method | level=%-5level | message=%msg %replace(%xException){'\n','\u2028'}%nopex%n
</Pattern>
</encoder>
</appender>
bit late. But if you are using spring boot you can use logback-spring.xml
and inside you can do something like
<appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<springProfile name="dev-local">
<pattern>FIST PATTERN</pattern>
</springProfile>
<springProfile name="!dev-local">
<pattern>SECOND PATTERN</pattern>
</springProfile>
</encoder>
</appender>
The question is simple. In some logback.xmls I see level as an element:
<logger name="mylog" additivity="false">
<level value="DEBUG" />
<appender-ref ref="fileAppender" />
</logger>
But in some it is written as an attribute:
<logger name="mylog" additivity="false" level="debug">
<appender-ref ref="fileAppender" />
</logger>
What is the difference?
Thanks.
In terms of configuring Logback, there is no difference. Both of the following declarations are functionally identical:
<logger name="com.x.y">
<level value="DEBUG"/>
</logger>
<logger name="com.x.y" level="DEBUG" />
Logback's configurer (have a look at ch.qos.logback.core.joran.GenericConfigurator.doConfigure()) creates an identical Logger instance for both of these declarations.
The only difference - when parsing the configuration - is that the first one manifests in more instances of ch.qos.logback.core.joran.event.SaxEvent (start and end events for the logger and for the level) than the second one (start and end events for the logger only).
If you are associating a logger with a specific appender then you'll already be defining a logger element body e.g.
<logger name="com.x.y">
<appender-ref ref="STDOUT"/>
</logger>
In which case defining a level within the element body rather than as an attribute might read better but it really is just a case of developer preference.
I want to configure Logback to fire an email whenever any warnings are found on server.
Right now it is already configure for error level we are getting mails when any error occurred. However same code with changing root level to warn doesn't work.
All sender, receiver, host etc. details are same for which use in error SMTP appender so it's not a server issue. Below is my code.
<appender name="EMAILWARN" class="ch.qos.logback.classic.net.SMTPAppender">
<smtpHost>XXXX</smtpHost>
<to>XXXX</to>
<!-- additional destinations are possible -->
<from>XXXX</from>
<!--
<discriminator class="ch.qos.logback.classic.sift.MDCBasedDiscriminator">
<key>req.remoteHost</key> visit http://logback.qos.ch/manual/mdc.html#mis for different key values
<defaultValue>default</defaultValue>
</discriminator>
-->
<!-- <subject>RCM-Error: ${HOSTNAME} %X{req.remoteHost} %logger - %m</subject> -->
<subject>Error: ${HOSTNAME} - %m %logger</subject>
<!-- <layout class="ch.qos.logback.classic.PatternLayout"> -->
<layout class="ch.qos.logback.classic.html.HTMLLayout">
<pattern>%date%X{REMOTE_ADDR}%X{USER_NAME}%level%logger%message</pattern>
</layout>
<cyclicBufferTracker class="ch.qos.logback.core.spi.CyclicBufferTrackerImpl">
<bufferSize>20</bufferSize> <!-- set number of log entry to send per email -->
</cyclicBufferTracker>
</appender>
<root level="warning">
<appender-ref ref="EMAILWARN" />
</root>
ch.qos.logback.classic.net.SMTPAppender use an evaluator to trigger the email send procedure. The default one triggers at ERROR level.
So what you need is an evaluator that tiggers at WARN level (and above)
<appender ... class="ch.qos.logback.classic.net.SMTPAppender">
...
<evaluator class="ch.qos.logback.classic.boolex.JaninoEventEvaluator">
<expression>return level >= WARN;</expression>
</evaluator>
...
</appender>
I'm pretty sure that warning is not a valid logback level.
Try changing your root logger level to warn:
<root level="warn">
<appender-ref ref="EMAILWARN" />
</root>
You can use filters as below, which will select log levels error and warn
<appender name="EMAILWARN" class="ch.qos.logback.classic.net.SMTPAppender">
<!-- rest of your configurations -->
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>WARN</level>
</filter>
</appender>
We are using quite a basic daily rolling configuration with logback, and it seems not to function properly. Application creates rolled (previous day) file usually in first minute after midnight. The yyyyMMdd fraction of file name contans previous day, that's correct. But messages in log are not from previous but from new day, only that 30-40 seconds !
For example, bim.2013-08-21.log file contains records with timestamps from 2013.08.22 00:00:00 to 2013.08.22 00:00:42. And all messages from previous day gets lost.
Also, there was some "lucky" exceptions when rolling started in the mid of the day , e.g. 16:00 , so we got more records rolled - from current day.
Logback version is 1.0.13
logback-test.xml :
<configuration scan="true" scanPeriod="10 minutes">
<contextName>bim</contextName>
<property name="LOG_DIR" value="/usr/share/apache-tomcat-7.0.41/logs" />
<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} %-5level %m \(%logger{36}:%L\)%n</pattern>
</encoder>
</appender>
<appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${LOG_DIR}/bim.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover -->
<fileNamePattern>${LOG_DIR}/bim.%d{yyyy-MM-dd}.log</fileNamePattern>
<maxHistory>5</maxHistory>
<cleanHistoryOnStart>true</cleanHistoryOnStart>
</rollingPolicy>
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %m \(%logger{36}:%L\)%n</pattern>
</encoder>
</appender>
<logger name="com.bim" level="DEBUG" />
<logger name="org.springframework.web.servlet.mvc.support" level="WARN" />

I have not found any traces of similar problems by search, so your help will be greatly appreciated.
I can't see what part are you missing over here. Even I have done the same and its working fine. Please check below link and try it in the same fashion :
https://github.com/abdulwaheed18/Slf4jTutorial/blob/master/sample7.xml
I want INFO for everything and DEBUG for one package. I've tried numerous variations of:
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="C:/temp/AutoTag.log"/>
<param name="AppendToFile" value="true"/>
<param name="MaxSizeRollBackups" value="2"/>
<param name="MaximumFileSize" value="100KB"/>
<param name="RollingStyle" value="Size"/>
<param name="StaticLogFileName" value="true"/>
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d [%t] ac.server %-5p %c - %m%n"/>
</layout>
</appender>
<root>
<level value="INFO"/>
<appender-ref ref="RollingFileAppender"/>
</root>
<logger name="AutoTagCore.net.windward.autotag.utils">
<level value="DEBUG"/>
</logger>
</log4net>
But nothing works. If I remove the <root/> part, I get the detailed in the one package. Otherwise it's as though the <logger/> part is not there.
How can I accomplish this? (Updated to show full log4net part).
Update2: I'm an idiot - I had the wrong package name in there.
Logger will inherit all appenders from root. You need to specify level only:
<root>
<level value="INFO"/>
<appender-ref ref="RollingFileAppender"/>
</root>
<logger name="AutoTagCore.net.windward.autotag.utils">
<level value="DEBUG"/>
</logger>
BTW Verify appender settings - it could be restricted to INFO level:
<threshold value="INFO"/>
And last possible issue - you can have different type namespace and logger name (maybe some typo).
