I am using slf4j & logback for logging and my application is deployed in Apache Service Mix where other modules are using my logging service. Everything works fine when i test it in a standalone environment but i face problem when i deploy it in a service mix container. At that time, only root level logging is effective and other logging levels are ignored.
Below is my logback-test.xml configuration, Kindly help i am stuck in this issue for the last 4 days.

As Servicemix 4.x is based on top of Karaf, the standard logging mechanism is Pax Logging. Pax Logging is configured by the org.ops4j.pax.logging.cfg file, as Karaf uses Configuration Admin Service to configure OSGi services. That's why the config file still uses the log4j properties notation.
If you need special appenders, some are already included like a MDC appender for logging bundle wise, or a ZipRollingFileappender.
Support for the external logback configuration was introduced with Pax Loggin 1.7 I think, and I doubt it is already included in ServiceMix 4.5.x
So you have to stick to the log4j notation or exchange the Pax Logging versions yourself.

I have a Java web app that I run in Eclipse for my development environment. I use logback for logging to a custom file. The problem is certain logging statements, specifically those that traditionally go to catalina.out, do not end up in my log file. They do show up in my Eclipse console, but not in my custom logback log file.
When I run the same app in tomcat outside of Eclipse (via startup.bat), those catalina logging statements do get captured in a catalina.out file. But when running in Eclipse no catalina.out is created, so those logs don't persist.
Here's my logback-test.xml:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<!-- RollingFileAppender that rolls based on size and time -->
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">

</appender>

<appender-ref ref="STDERR"/>
</root>
</configuration>
This answer resolved my question: https://stackoverflow.com/a/5045247/3368818
Apparently, if, while running an app on tomcat via Eclipse, you want to capture the catalina logs in a file, you need to specify that via the Eclipse tomcat launch configuration settings.
I guess in a way this makes sense in that the catalina logs are perhaps not application specific, so maybe outside the scope of logback appenders. But on the other hand, shouldn't they get written to a log file by default anyway, just as they do if you launch your tomcat server outside of Eclipse?
I have no idea how to debug since there is no errors. I have this logback file but this made all the logs disappear for my cloudrun instance EXCEPT the system.out stuff that logback logs on startup..

Any ideas why logging stops working or where the logging is going to? Now that I changed logging to this, logging seems to go to the void :(.
I also tried out this post which logs to ConsoleAppender but NOTHING shows up in the json format although it is doing a line for EACH log statement I do which is really nice
GKE & Stackdriver: Java logback logging format?
I then tried this approach which is using FileAppender
How do I map my java app logging events to corresponding cloud logging event levels in GCP Felexible non-compat App Engine?
My logback for this one was
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>/var/log/app.log</file>
<append>true</append>
<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
<layout class="com.orderlyhealth.GCPCloudLoggingJSONLayout">
<pattern>%-4relative [%thread] %-5level %logger{35} - %msg</pattern>
</layout>
</encoder>
</appender>
<appender name="ASYNC-SERVERLOG" class="ch.qos.logback.classic.AsyncAppender">
<appender-ref ref="FILE" />
</appender>
Any ideas?
The Java logging instructions in the documentation should help: https://cloud.google.com/run/docs/logging#run_manual_logging-java
In Cloud Run, output to Stdout and Stderr are forwarded on to Stackdriver. Logs which are recorded in files are lost.
I'm not sure the implications of the ASYNC-SERVERLOG appender, but on Cloud Run there is only CPU available to process and send logs while a request is being processed, so if something is asynchronously sending logs it will only work during that request or a future request that reaches the same container instance.
I'm using an application called Apache Drill that uses logback for logging. I'm trying to edit it's shipped logback.xml configuration file to output debugging messages.
Here is the file, untouched

And absolutely nothing changed !
This is the java command used to start the application (Search for -cp /home/gelbana/drillv11/conf, the logback.xml file is located in the conf directory)

The drillbit.out file has the following lines at the beginning
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/gelbana/drillv11/jars/3rdparty/slf4j-simple-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/home/gelbana/drillv11/jars/classb/logback-classic-1.0.13.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.SimpleLoggerFactory]
I tried changing all levels to DEBUG, ALL but still, nothing changed. I can't find a single DBEUG in the logs.
The changes you made should work. I made the same change and ran a drillbit and I can see debug logs in drillbit.log. For example:
DEBUG o.a.drill.exec.server.StartupOptions - Parsing arguments.
The drillbit.out file should tell you something about how Logback configured itself. Have a look at that file, specifically the entries which relate to LoggerContext for example:
Found resource [logback.xml] at ...
Resource [logback.xml] occurs multiple times on the classpath
And you'll likely find that Logback relveals the answer via it's own logging.
we are using logback for our logging and we have following jars in our class path
jcl-over-slf4j-1.7.7.jar
logback-classic-1.1.3.jar
logback-core-1.1.3.jar
slf4j-api-1.7.7.jar
janino-2.7.8.jar
In each app, i have minimal config in logback.xml. Like this
<configuration scan="true" scanPeriod="10 seconds">
<statusListener
class="ch.qos.logback.core.status.OnConsoleStatusListener" />
<contextName>myapp- ${HOSTNAME}</contextName>
<include file="${logback.path}/logback.xml"/>
</configuration>
Then in my file system, I have config like this
<included>
<property name="LOG_HOME" value="C:\\tmp" />
<appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>%d{yyyy-MM-dd-HH:mm:ss.SSS} cn=%contextName [%thread] %-5level %logger{36} - %msg%n</Pattern>
</layout>
</appender>

<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">

</rollingPolicy>
<encoder>

</appender>

<logger name="com" level="INFO"/>
<root level="INFO">

<appender-ref ref="file" />
</root>
Now when i deploy my app, i do see logs from spring framework in application.xxx.log file but my actual application code which logs some statement are not showing up in this log file
In my code, i m using slf4j logger factory to get the logger and then just log some dummy statements, like this
private static final Logger logger = LoggerFactory.getLogger(GameService.class);
logger.info("Playing cricket game.......");
I think i figured out the issue. Some where in our lib, we were using common logger util class which was modifying logger context object. As soon as i removed that dependency , things worked out fine. Since that was the old way of logging , we no longer needed common logger util.
I have this simple Logback config file, containing two appenders and some custom logging levels based on package name.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<configuration>
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<charset>UTF-8</charset>
<pattern>%date{HH:mm}\t%-5level\t%msg%n</pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>my_logger.log</file>
<encoder>
<charset>UTF-8</charset>
<pattern>%date{dd MMM HH:mm}|%class{0}|%-5level|%msg%n</pattern>
</encoder>
</appender>
<!-- custom logging levels -->
<logger name="myapp.package1" level="INFO" />
<logger name="myapp.package2" level="INFO" />
<root>
<appender-ref ref="CONSOLE" />
<appender-ref ref="FILE" />
</root>
</configuration>
With this configuration, the custom logging levels are applied for both appenders.
How can I change it so that only ConsoleAppender uses these custom logging levels, while FileAppender sticks to default levels?
If you don't want to implement a custom filter, you can create a new appender with a fixed threshold (in you case INFO):
<appender name="INFO_CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
...
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>INFO</level>
</filter>
</appender>
Then, for your custom logging levels add the INFO_CONSOLE and your FILE appender. The additivity="false" attribute prevents the logger from logging to the CONSOLE appender inherited from root.
<logger name="myapp.package1" additivity="false">
<appender-ref ref="INFO_CONSOLE" />
<appender-ref ref="FILE" />
</logger>
This should log DEBUG and above to the FILE and CONSOLE appenders, except for myapp.package1 which will only log INFO and above to CONSOLE.
