I want to delete the log file each time the program is started as opposed to it being appended. I've tried using the cleanHistoryOnStart property but that seems to have no effect whatsoever. I'm probably missing something here.
I am on Linux and using Eclipse if that matters.

Include <param name="Append" value="false" /> in your appender to clean the log file on start up.
Otherwise try this one

How can I convert logback.xml file to properties?
For example, there is such a configuration file or the code I have attached below. I need to write similar properties in application.properties
Are there examples for such configurations?
is it correct to use the example from this question?

When I check inside log directory, I only saw abc.log , but no mon.log
Did you notice the slash missing inside in second logger??
<file>${HOME}/mon.log</file>
I believe that's the problem. However, nothing to do with spring boot :)

I use this config on two ubuntu servers. On the first server the config works as expected (it writes the log to file). However, on the second server logback does not write the log to file.
Is there something wrong with my config or is the error elsewhere in the project?

I want the console logging to turn off and file logging to turn on. Is this possible in logback?

I am open to use another logging libraries if this is not possible in logback.
Delete the appender-ref STDOUT reference
<root level="INFO">
<appender-ref ref="FILE" />
</root>
I don't know logback but you might set logging level to OFF for the console logger.
Like this (removing STDOUT appender from root logger) :
<logger name="consoleLogger" level="OFF">
<appender-ref ref="STDOUT" />
</logger>
<root level="INFO">
<appender-ref ref="FILE" />
</root>
See : Can I disable an appender in logback?
EDIT : added XML sample
I have an application, in which I use logback. My logback.xml file is like so :
<configuration>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>myApp.log</file>
<encoder>
<Pattern>%date{"yyyy-MM-dd'T'HH:mm:ss", UTC} [%thread] %-5level %logger{36} %L - %msg%n</Pattern>
</encoder>
</appender>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<Pattern>%date{"yyyy-MM-dd'T'HH:mm:ss", UTC} [%thread] %-5level %logger{36} %L - %msg%n</Pattern>
</encoder>
</appender>
<logger name="source.main.FileProcess" level="INFO" />
<logger name="source.main.FileReadWrite" level="INFO" />
<logger name="source.main.OperatorLoader" level="DEBUG" />
<logger name="source.exception.ValidationException" level="INFO" />
<logger name="source.validation.Validation" level="INFO" />
<logger name="source.main.OperatorLoader" level="DEBUG" />
<root level="debug">
<appender-ref ref="FILE" />
<appender-ref ref="STDOUT" />
</root>
</configuration>
Now I want to say if my myApp.log file's size become 100 KB then convert it to a zip the myApp.log .
Can anyone help me to do this?
You can use something like below, this is what I use in our project. It creates folder for the month, and keeps daily file in it in gz format
<timestamp key="date" datePattern="yyyy-MM-dd"/>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>myApp.log</file>
<append>true</append>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>archived_logs_%d{yyyy-MM,aux}/myApp_%d{yyyy-MM-dd}.log.gz</fileNamePattern>
</rollingPolicy>
<maxHistory>180</maxHistory>
<encoder>
<pattern>[%d{yyyy.MM.dd HH:mm:ss.SSS}] [%t] [%p] [%logger{5}] [%X] %msg%n</pattern>
</encoder>
</appender>
if you read here, there is a section stating that FixedWindowRollingPolicy, TimeBasedRollingPolicy appenders will compress the log file if the name specified ends with .zip or .gz
Just like FixedWindowRollingPolicy, TimeBasedRollingPolicy supports
automatic file compression. This feature is enabled if the value of
the fileNamePattern option ends with .gz or .zip.
I guess it will something like
<file>test.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>tests.%i.log.zip</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>3</maxIndex>
</rollingPolicy>
