hy guys,
is there a best practice of how to get flyway output into log4j logs?
I'm currently running with following log4j.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration>
<appender name="CA" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-p - %m%n"/>
</layout>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="levelMin" value="INFO"/>
<param name="levelMax" value="ERROR"/>
</filter>
</appender>
<appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
<param name="append" value="false"/>
<param name="file" value="log.out"/>
<param name="immediateFlush" value="true"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n"/>
</layout>
</appender>
<logger name="com.googlecode.flyway.core.migration" additivity="false">
<level value="DEBUG"/>
<appender-ref ref="fileAppender"/>
</logger>
<root>
<priority value="all"/>
<appender-ref ref="CA"/>
<appender-ref ref="fileAppender"/>
</root>
</log4j:configuration>
I have already searched for an answer online but could not figure it out.
Flyway will automatically use Log4J if it is available on the classpath.

I am relatively new to Spring MVC framework and it's logging concepts. When I run an application and an exception occurs(For Ex: NullPointerException), the stack trace is being displayed on the browser itself. the console just says there is an exception.
My problem is that most of the stack trace is not visible on the browser because the layout does not have enough width. Is there a way to make the stack trace print in the console? Thanks.
Here is my log4j.xml in case:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

Try specify
<param name="ConversionPattern" value="%-5p: %c - %m%n%ex" />
I have a web service set up in my IIS, the appender that logs to a text file is working fine (the text file is in the same directory as where the web service is running from). The appender that writes to the Event Viewer isn't working, I'm currently connected to the web service as administrator so I should in theory be able to do this, what else should I check/see if I'm missing?
log4net.config:
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{ABSOLUTE} [%thread] %level %logger - %message%newlineExtra Info: %property{testProperty}%newline%exception"/>

The best way to find out what is going wrong is enable log4net interal debug, this will tell you where log4net is failing:
<configuration>
...
<appSettings>
<add key="log4net.Internal.Debug" value="true"/>
</appSettings>
...
<system.diagnostics>
<trace autoflush="true">
<listeners>
<add
name="textWriterTraceListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="C:\tmp\log4net.txt" />
</listeners>
</trace>
</system.diagnostics>
</configuration>
Log4net FAQ
I'd like to configure log4cxx via xml in order to roll my log file every minute. I tried with the following log4j.xml file but it seems to work only sometimes, randomly. I tried also with another xml file using TimeBasedRollingPolicy but it doesn't work.
Any help would be appreciated.

this is my config for log4net but it wont write to the console
see appender: ConsoleAppender
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

</layout>

<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" >

Why doesn't it write to the console?
Edit 1
This is how I initialize it:
log4net.Config.XmlConfigurator.Configure(new FileInfo("C:\\Users\\name\\Documents\\Visual Studio 2010\\Projects\\ExecutionEngine\\Libraries\\App.Config"));
Thanks
You can use the trace appender for this purpose. For instance like this:
<appender name="TraceAppender"
type="log4net.Appender.TraceAppender" >
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%-6level - %message%newline" />
</layout>
</appender>
For Log4Net used in ASP.NET,
how do I specify specify different levels to separate appenders in web.config?
Thanks.
Pure guesswork at play here.
Looked at the documentation & thought, this could be the way to do it.
Note: DEBUG level messages are logged to console & WARN level messages are logged to eventlog.
I hope it works :)
<log4net>
<!-- A1 is set to be a ConsoleAppender -->
<appender name="A1" type="log4net.Appender.ConsoleAppender">
<!-- A1 uses PatternLayout -->
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%-4timestamp [%thread] %-5level %logger %ndc - %message%newline" />
</layout>
</appender>
<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender" >
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
<logger name="DebugLogger">
<level value="DEBUG" />
<appender-ref ref="A1" />
</logger>
<logger name="WarnLogger">
<level value="WARN" />
<appender-ref ref="EventLogAppender" />
</logger>
</log4net>
This works for SmtpAppender at least. Guess it will work for other appenders too, but I haven't tested it
<evaluator type="log4net.Core.LevelEvaluator">
<threshold value="WARN"/>
