I am trying to log the spring boot applications logs to a separate directory(apps-archive ie ${catalina.base}/logs/apps-archive/log.log) in the external tomcat. After I start the server the log file is empty, and there are some logs in catalina.2021-04-04.log file about application is deployed and so...
In my spring boot application I have logback-spring.xml in src/main/resources as
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

I have no configuration for logging in application.properties file. Can anyone please suggest me why logs file is empty in apps-archive directory on server.
The default profile spring boot apps run with is default.
Can you please change
<springProfile name="dev">
to
<springProfile name="default">
Regarding the issues with the RollingPolicy I don't have any ideas at the moment.

I have a spring boot microservice application. logback.xml is configured to write the logs to a location on the server. In addition to this, I want to write logs from a particular java class to Syslog. I do not want logs from all other classes to be written to syslog but to a rolling file appender. Is there a way to configure this using logback.
below is my logback.xml

<appender-ref ref="SPECIFIC_CLASS"/>
</logger>
</configuration>
From the above XML, SYSLOG and SPECIFIC_CLASS appenders are used to write logs from ActivityLogAspect class. When I run my application I see that only SPECIFIC_CLASS is working. I don't see any logs written to /var/log/messages. But if I add the SYSLOG appender along with the console appender, I see the messages written to /var/log/messages.
I do not want logs from all classes written to syslog but only from one particular class.
Please advise.
I'm creating a logback-common config file for my applis.
I'm defining a RollingFileAppender in it, that for all my applis generates the same log format in a file (if we need it).
Sometimes I want to use this appender, and sometimes not (when we test for example).
So we configure our specific logback-{profile}.xml depending what we want.
But when we do not use the FILE appender, the file gets created and I would like not.
I have:
logback-common.xml >> with all appenders definition (FILE and COMMON)
appli_one
resources/logback.xml >> call logback-common and config/logback-{profile}.xml
resources/config/logback-{profile}.xml >> specific appli/profile logback configuration.
To configure we can do in logback-{profile}.xml

Not a core feature of logback but there are workarounds to achieve lazy file initialization.

Logback - do not create empty log files at startup
I use logback to print log in my SpringBoot application. When I check out the log file, I found that, all log message print twice! It is so strange .
Yeah, I have found some answer similar to my issue. But maybe they are not what I want.
here is my logback.xml:

How can I make sure log messages appear only once. Thank you.
It is because you have added ASYNC and FILE for INFO.
Please remove one of them based on your requirement.
Is it anyway to send startup logs to file, right now all logs up to the statement "Started Application in...." goes to stdout, I want all logging to file.

You need to configure your logging framework. Assuming you're just using the default from spring-boot then that's LogBack. So have a look at their docs or have a search, there are many useful resources (like this one)
If you add a logback.xml file with the following content to your resources folder you should get logging to both console and file (called application.log) in the same format as you now see for just console.
<configuration>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>application.log</file>
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="info">
<appender-ref ref="FILE" />
<appender-ref ref="STDOUT" />
</root>
</configuration>
You probably want to use a RollingFileAppender as this will allow you to create new files when the log file gets big.
We followed all the posts and documentation out there but can't get any DEBUG statements generated by Hazelcast.
Hazelcast v.3.4.1 Tomcat 7 application server. Slf4j v.1.7.5
Hazelcast config:
<properties>
<property name="hazelcast.logging.type">slf4j</property>

EDIT: Here is a full logback.xml
<configuration scan="true">
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} %-5level %logger{0} - [%X{sessionID}] - [%X{loginID}] - %msg%n</pattern>

</logger>
<root level="warn">

</root>
Seems like something else is needed. No hazelcast logging is visible.
I would appreciate some help.
Do you see somethng like this in the logging?
INFO: [192.168.122.1]:5701 [dev] [3.5.1]
Members [1] {
Member [192.168.122.1]:5701 this
}
Because this is a clear indication that the Hazelcast logging is working correctly. If you don't see this, then there really is a logging problem, otherwise there probably is some kind of log level problem.
