Different log files using Logback - java

I would like to log different log levels to different files , In addition to this I would like to have the default consoleAppender as well for each log level.
So the output should be different log level files :
Info level file
Warn level file
Error level file
Console should also remain enabled all the time.

<root level="warn">

<appender-ref ref="FILEWARN" />
</root>
</configuration>
The problem here is it writes each type of level in all files.

Update the filter definitions to include: <onMismatch>DENY</onMismatch>, for example:
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>INFO</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
The default behaviour for onMismatch is FilterReply.NEUTRAL so by not including a onMismatch declaration you are effectively allowing all entries through the filter whether they match the given level or not.
You should also remove the multiple <root> declarations and replace them with this one:
<root level="info">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
<appender-ref ref="FILEWARN" />
<appender-ref ref="FILEERROR" />
</root>
This declaration will cause all four of those appenders to be running and then the filter within each of the FILE, FILEWARN and FILEERROR appenders will ensure that they only handle log events of the correct level.

This is what I have done , and it is working.

Logback : add new log with different level for Dev and Prod environment

I want to add new log file myNewLog.log, I wont to use different logger level in different environment without infect the existing log. The levels of the dev environment and the prod environment are mentioned in below description :

My questions are :
how can I manage log level for each environment ?
can I manage the levels for the 2 environments in one logback file ?
in application.yml, use different profile for each environment. and define level var my.log.level
logging:
config: classpath:logback.xml
--- #dev
spring:
profiles:
- dev
my:
log:
level: DEBUG
--- #prod
spring:
profiles:
- prod
my:
log:
level: ERROR
in logback.xml use "<springProperty>" to import this var.
if logback.xml is not effective, please rename it to logback-spring.xml to try again.

How to exclude error log level in a file logback spring boot

I have a spring boot app(spring-boot-starter-parent --> 2.3.0.RELEASE) that I am implementing log.
Basically what I am trying to achieve is that I have 2 log files one bridgeError.log which contains only error messages and bridge.log which will contain all log level except Error level since it is being logged in brideError.log file.
I am able to create 2 logs file brideError.log which contains only error messages but the issue is that
bridge.log also contains error messages.
Please find my logback-spring.xml configuration below:

Is it possible to exclude error messages in bridge.log file?
Thanks in advance
You can use a level filter for that purpose
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>ERROR</level>
<onMatch>DENY</onMatch>
<onMismatch>ACCEPT</onMismatch>
</filter>

But after using above logback.xml file, logs are still going to ${appLogFile} ( appLogFile is system Property and have absolute file path) for both parent as well as child packages. Can someone help me what i am doing wrong here ?
I want to move logs for com.xyz.a.b.c --> File1

I got the answer. it was my mistake only. changed the logback.xml file to move it

Different log files for different log levels in logback

I am trying to insert log information into files based on Log level using below Logback configuration . I would like to insert log information to each different file (like info into info file, debug into debug file..) to achieve this i am using the below configuration file and with this i can insert info information into info file successfully. But i am not able to insert debug information into debug file.Pls help me on this how to over come. Thanks.

1) Why debug logs are not getting printed?
A log request of level p issued to a logger having an effective level
q, is enabled if p >= q.
It assumes that levels are ordered as follows: TRACE < DEBUG < INFO < WARN < ERROR.
Set the root logger level as "DEBUG", which is it's default value.
2) Change your logback configuration as below,:-
<appender name="FILE-INSERT-DEBUG"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>DEBUG</level>
<onMismatch>DENY</onMismatch>
</filter>
<file>${DEV_HOME}/debug.log</file>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>
%d{yyyy-MM-dd HH:mm:ss} - %msg%n
</Pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>${DEV_HOME}/archived/debug.%d{yyyy-MM-dd}.%i.log.zip
</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>10MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
</appender>
<appender name="FILE-INSERT-INFO"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>INFO</level>
<onMatch>ACCEPT</onMatch>
</filter>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>DEBUG</level>
<onMatch>DENY</onMatch>
</filter>
<file>${DEV_HOME}/INFO.log</file>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<Pattern>
%d{yyyy-MM-dd HH:mm:ss} - %msg%n
</Pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- rollover daily -->
<fileNamePattern>${DEV_HOME}/archived/INFO.%d{yyyy-MM-dd}.%i.log.zip
</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>10MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
</rollingPolicy>
</appender>
<root level="DEBUG">
<appender-ref ref="FILE-INSERT-DEBUG" />
<appender-ref ref="FILE-INSERT-INFO" />
</root>
You can easily extend the above configuration for other levels.

How do I get only specific level of message in my log file?

I am trying to write logs in two files, in one file I am ok to get the logs of any level, and in other file I am looking for only INFO level. Is this possible?
<configuration>
<appender name="fileAppender" class="ch.qos.logback.core.FileAppender">
<file>c:/log/myLogFile.log</file>
<append>true</append>
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>DEBUG</level>
</filter>
<encoder>
<pattern>%d [%thread] %-5level %logger{35} - %msg%n</pattern>
</encoder>
</appender>
<appender name="EVENTS_FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>c:/log/myLogFile-event.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>../logs/cweo-app-event-%i.log.gz</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>30</maxIndex>
</rollingPolicy>
<triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>100MB</maxFileSize>
</triggeringPolicy>
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>INFO</level>
</filter>
<encoder>
<pattern>%msg%n</pattern>
</encoder>
</appender>
<!-- <logger name="event" level="DEBUG"> <appender-ref ref="EVENTS_FILE"
/> </logger> -->
<root>
<appender-ref ref="fileAppender" />
<appender-ref ref="EVENTS_FILE" />
</root>
This is my logback.xml where in EVENTS_FILE I want to print only INFO messages nothing else.
Don't use ThresholdFilter, use LevelFilter.
LevelFilter provides equality testing, unlike ThresholdFilter. See Filters.
In this case:
<appender name="EVENTS_FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>c:/log/myLogFile-event.log</file>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>INFO</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
