Log back configuration error while running JUnit - junit

I configured logback.xml in my application and it's working fine. But after working some days, while running Junit test cases i got the below error.
java.lang.IllegalStateException: Logback configuration error detected:
ERROR in ch.qos.logback.core.rolling.RollingFileAppender[STDOUT] - Appender [STDOUT] failed to append. java.lang.IllegalArgumentException: Cannot convert 1 of typejava.lang.Integer

I am unable to figure it out the issue. It seems Rolling file is not generating after reached max size. Any help Appreciated.


Update your rolling policy with
<minIndex>1</minIndex>
<maxIndex>10</maxIndex>

Logback.xml is not generating the logs separately for error and debug in separate rollingfile

I want to generate logs in separate file for different level like error or debug. Means when root level is enable for Debug the logs should be generated in debug file only. And when root level is enable for error the logs should be generated in error file. But for my logback.xml configuration the logs are generating in both the files as the same time.
Please help.

logback smtpAppender mailing on both error and info log level

I am trying to use logback SMTP appender to send email alerts.
I am getting emails only when log level is 'error' (I know this is by default).
How do I get emails when log level is being set to 'info'?
<property resource="application.properties"/>
<appender name="EMAIL" class="ch.qos.logback.classic.net.SMTPAppender">
<smtpHost>${spring.mail.host}</smtpHost>
<username>${spring.mail.username}</username>
<password>${spring.mail.password}</password>
<smtpPort>${spring.mail.port}</smtpPort>
<STARTTLS>false</STARTTLS>
<SSL>true</SSL>
<subject>Exception: Registraion App %m</subject>
<to>${spring.mail.to}</to>
<from>${spring.mail.from}</from>
<asynchronousSending>true</asynchronousSending>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%date %-5level %logger{35} - %message%n</pattern>
</layout>
</appender>
<logger name="errorLogger" level="error" additivity="false">
<appender-ref ref="EMAIL"/>
</logger>
In the java class I am invoking this as below
public static final Logger emailExceptionLOGGER = LoggerFactory.getLogger("errorLogger");
try{
.....
}catch(Exception e){
emailExceptionLOGGER.error("To send exception email")
}
I would also like to send success emails when log level is being set to 'info'
<appender name="SUCCESS-EMAIL" class="ch.qos.logback.classic.net.SMTPAppender">
<smtpHost>${spring.mail.host}</smtpHost>
<username>${spring.mail.username}</username>
<password>${spring.mail.password}</password>
<smtpPort>${spring.mail.port}</smtpPort>
<STARTTLS>false</STARTTLS>
<SSL>true</SSL>
<subject>Registraion App %m</subject>
<to>${spring.mail.to}</to>
<from>${spring.mail.from}</from>
<asynchronousSending>true</asynchronousSending>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%date %-5level %logger{35} - %message%n</pattern>
</layout>
</appender>
<logger name="successLogger" level="info" additivity="false">
<appender-ref ref="SUCCESS-EMAIL"/>
</logger>
In the java class I am invoking this something like below
public static final Logger emailSuccessLOGGER = LoggerFactory.getLogger("successLogger");
if(success){
emailSuccessLOGGER.info("To send success email")
}
I would like to handle both together. Thanks in advance.

include below after layout in your email appender. It should filter out info logs.
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>ERROR</level>
</filter>

I had encountered the same error while using 4.7 version of the logstash-logback-encoder, and upgrading to 4.11 resolved the issue.

NumberFormatException: For input string: "-" logback

I need to print the class, method and line number in the logger. For that I am using the following entry:
<appender name="ErrorFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${log.dir}error.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<!--<totalSizeCap>10MB</totalSizeCap>-->
<TimeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<MaxFileSize>10MB</MaxFileSize>
</TimeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>

</Pattern>
</encoder>
<!--<encoder>
<pattern>%d %-5p [%X{sessionId}] [%X{userId}] %C{1}.%-M:%L] %m%n</pattern>
</encoder>-->
</appender>
<root level="ERROR">
<appender-ref ref="ErrorFileAppender" />
</root>
As you can see, my pattern is
%d %-5p [%X{sessionId}] [%X{userId}] %C{1}.%-M:%L] %m%n
Then I am getting the following error:

But if I use
%d %-5p [%X{sessionId}] [%X{userId}] %m%n
Then there is no error.
Can someone please take a look. Here is my pom entry:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.7.25</version>
</dependency>
<dependency>
<groupId>org.logback-extensions</groupId>
<artifactId>logback-ext-spring</artifactId>
<version>0.1.4</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.2.3</version>
<scope>test</scope>
</dependency>

change %-M to %M.
So your pattern becomes:
<Pattern>
%d %-5p [%X{sessionId}] [%X{userId}] %C{1}.%M:%L] %m%n
</Pattern>

Backlog multi appender with different level

How can I log everything to WARN to a file and the console, but my.package to DEBUG only for file?
I tried:
<configuration>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{5} - %msg%n</pattern>
</encoder>
<File>target/log/test-log</File>
<append>false</append>
</appender>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{5} - %msg%n</pattern>
</encoder>
</appender>
<logger name="my.package" level="WARN">
<appender-ref ref="STDOUT"/>
</logger>
<logger name="my.package" level="DEBUG">
<appender-ref ref="FILE" />
</logger>
<root level="WARN">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
</root>
</configuration>
But it would log everything to DEBUG in the console too.
This also doesn't work:
<configuration>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{5} - %msg%n</pattern>
</encoder>
<File>target/log/test-log</File>
<append>false</append>
</appender>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{5} - %msg%n</pattern>
</encoder>
</appender>
<logger name="io.chumps">
<appender-ref ref="STDOUT" level="WARN"/>
<appender-ref ref="FILE" level="DEBUG" />
</logger>
<root>
<appender-ref ref="STDOUT" level="WARN" />
<appender-ref ref="FILE" level="WARN" />
</root>
</configuration>

Solved it using GEventEvaluator with custom Groovy scripting:
http://logback.qos.ch/manual/filters.html#GEventEvaluator
<configuration>
<property name="LAYOUT" value="%d{HH:mm:ss.SSS} [%thread] %-5level %logger{5} - %msg%n" />
<root>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<filter class="ch.qos.logback.core.filter.EvaluatorFilter">
<evaluator class="ch.qos.logback.classic.boolex.GEventEvaluator">
<expression>e.level.toInt() >= WARN.toInt()</expression>
</evaluator>
<OnMatch>ACCEPT</OnMatch>
<OnMismatch>DENY</OnMismatch>
</filter>
<encoder>
<pattern>${LAYOUT}</pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<filter class="ch.qos.logback.core.filter.EvaluatorFilter">
<evaluator class="ch.qos.logback.classic.boolex.GEventEvaluator">
<expression>
e.level.toInt() >= WARN.toInt() ||
(e.level.toInt() >= TRACE.toInt() && e.getLoggerName().startsWith("my.package"))
</expression>
</evaluator>
<OnMatch>ACCEPT</OnMatch>
<OnMismatch>DENY</OnMismatch>
</filter>
<encoder>
<pattern>${LAYOUT}</pattern>
</encoder>
<File>target/log/test-log</File>
<append>false</append>
</appender>
</root>
</configuration>
I can't believe this so simple usecase is not supported by default.
