I am facing trouble converting it to log4j 2. How i can addmy custom pattern layout.
You should implement your CustomPatternLayout as a Layout plugin. You have a code example on (layout plugins manual).
In very general you should :
Implement the plugin class with proper annotations on the constructor
Implement the plugin factory method
Implement the desired formatting
Mention in log4j configuration your plugins package:
<Configuration packages="com.mayank.base.logging">
Use in the configuration the name of your plugin class
You can see explanations and examples of plugins implementation on this blog post1, post2, post3. There is no layout plugin example, but the technique is very similar.
The <RollingFile> tag should be present.
Here are couple of samples -
<RollingFile name="ROLLING"
fileName="f:/my_dir/logsroll.log"
filePattern="f:/my_dir/logsroll-%i.log">
OR
<RollingFile name="MyFile" fileName="d:/log/bsi/admin/total/totalLog.log"
filePattern="d:/log/totalLog-%d{MM-dd-yyyy}-%i.log">
<PatternLayout>
<Pattern>%d %p %c [%t] %m%n</Pattern>
</PatternLayout>
<Policies>
<TimeBasedTriggeringPolicy />
<SizeBasedTriggeringPolicy size="1 MB"/>
</Policies>
<DefaultRolloverStrategy max="2000"/>
</RollingFile>

I read the official document of log4j2 and get a question about RollingFileAppender.
That's what the document says:
Below is a sample configuration that uses a RollingFileAppender with both the time and size based triggering policies, will create up to 100 archives on the same day (1-100) that are stored in a directory based on the current year and month, and will compress each archive using gzip and will roll every hour. During every rollover, this configuration will delete files that match "/app-.log.gz" and are 30 days old or older, but keep the most recent 100 GB or the most recent 10 files, whichever comes first.
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" name="MyApp" packages="">
<Properties>
<Property name="baseDir">logs</Property>
</Properties>
<Appenders>
<RollingFile name="RollingFile" fileName="${baseDir}/app.log"
filePattern="${baseDir}/$${date:yyyy-MM}/app-%d{yyyy-MM-dd-HH}-%i.log.gz">
<PatternLayout pattern="%d %p %c{1.} [%t] %m%n" />
<Policies>
<TimeBasedTriggeringPolicy />
<SizeBasedTriggeringPolicy size="250 MB"/>
</Policies>
<DefaultRolloverStrategy max="100">
<!--
Nested conditions: the inner condition is only evaluated on files
for which the outer conditions are true.
-->
<Delete basePath="${baseDir}" maxDepth="2">
<IfFileName glob="*/app-*.log.gz">
<IfLastModified age="30d">
<IfAny>
<IfAccumulatedFileSize exceeds="100 GB" />
<IfAccumulatedFileCount exceeds="10" />
</IfAny>
</IfLastModified>
</IfFileName>
</Delete>
</DefaultRolloverStrategy>
</RollingFile>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="RollingFile"/>
</Root>
</Loggers>
</Configuration>
I think this configuration will create up to 100 archives on the same hour of the day, not 100 archives on the same day, can anybody who give me a hand? Thanks!
Yes, it will keep up to 100 files in the hour but in reality it will never get that high since it is only keeping a maximum of 10 files overall.
Hello I am using Log4j2 for my logging and I am little confused as to how I can log message to a different file based on the message prefix.
For example, currently all messages are logged in a single logs folder.
A set of my messages look like this:
'com.project.latency: ProjectName=[MooPointProject].......'
Some of my other log messages are of the format:
'com.project.latency: ProjectName=[DataPlaneProject].......'
I want to log the messages which contain the MooPointProject in a specific file and one containing DataPlaneProject in a separate log file.
Is there a specific way I can do that other than changing the logging level itself?
Set up several appenders one for each project name. For example:
<RollingFile name="RollingFile" fileName="logs/MooPointProject.log"
filePattern="logs/app-%d{MM-dd-yyyy}.log.gz">
<RegexFilter regex=".*MooPointProject.*" onMatch="ACCEPT" onMismatch="DENY"/>
<PatternLayout>
<pattern>%d %p %c{1.} [%t] %m%n</pattern>
</PatternLayout>
<TimeBasedTriggeringPolicy />
</RollingFile>
and
<RollingFile name="RollingFile" fileName="logs/DataPlaneProject.log"
filePattern="logs/app-%d{MM-dd-yyyy}.log.gz">
<RegexFilter regex=".*DataPlaneProject.*" onMatch="ACCEPT" onMismatch="DENY"/>
<PatternLayout>
<pattern>%d %p %c{1.} [%t] %m%n</pattern>
</PatternLayout>
<TimeBasedTriggeringPolicy />
</RollingFile>
Then assign both the appenders to your logger(s). Since your RegexpFilter accepts only a project-spcific lines you will get them to the appropriate files separately.
P.S. - Find the detail on other types of filters here.
I've tried to add the following RollingFile appender;
<RollingFile name="appFile" fileName="${sys:catalina.base}${sys:file.separator}logs${sys:file.separator}${web:contextPath}${sys:file.separator}app.log" filePattern="app-%d{dd-MM-yyyy}.log">
<PatternLayout pattern="%d{dd/MM/yyyy HH:mm:ss} %c{2} - %m%n" />
<Policies>
<TimeBasedTriggeringPolicy />
<SizeBasedTriggeringPolicy size="250 MB" />
</Policies>
<DefaultRolloverStrategy max="20" />
</RollingFile>
The file is created in the correct path but the name is always the same (app.log) instead of app-xx-xx-xxxx.log.
What do I miss?
The filePattern attribute is the pattern of the file name to use on rollover. But if you want the date pattern in the name of the file that is actively written tom, you can use Date Lookup in the filename attribute, i.e:
fileName="${sys:catalina.base}${sys:file.separator}logs${sys:file.separator}${web:contextPath}${sys:file.separator}app-${date:dd-MM-yyyy}.log"
Can someone tell me, How to configure custom layout for FileAppender?
Can anyone tell me, how to configure custom layout for FileAppender?
I'm created copy of HTMLLayout and made some changes there (it's cannot be extends because it's final class) and now I want use this layout, but I don't know how :(
This error is showed with bellow listed configuration:
ERROR File contains an invalid element or attribute "ibtrader.log4j2.MYHTMLLayout"
Here is my log4j2.xml configuration file

Thanks for help!
The comments mention this is already fixed but just for completeness, a (simplified) configuration with a custom MYHTMLLayout plugin could look like this:
<?xml version="1.0" encoding="UTF-8"?>
<!-- the packages attribute contains a comma-separated list
of the packages that Log4J2 will scan for custom plugins. -->
<configuration packages="ibtrader.log4j2">
<appenders>
<appender name="HTMLAppender" type="File" fileName="logs/mainlog.html">
<!-- Each plugin has a *name*, declared with annotation on the
plugin implementation class.
The plugin name does not need to match the class name.
The plugin name needs to match the *type* attribute in the config.
For example:
package ibtrader.log4j2;
import ...;
#Plugin(name="MYHTMLLayout", category="Core",
elementType="layout", printObject=true)
public class MyHTMLLayoutImpl extends AbstractStringLayout {...
-->
<layout type="MYHTMLLayout" charset="UTF-8" title="IBTRader logs" locationInfo="true" />
</appender>
</appenders>
<loggers>
<root level="trace">
<appender-ref ref="HTMLAppender" />
</root>
</loggers>
</configuration>
You have to extend AbstractStringLayout, setting the #Plugin properties with category = "Core", elementType = "layout" and name="The name of the class itself that should be refered from the configuration file" (i.e.: "ExtHtmlLayout")
You could just copy the whole class HtmlLayout from the sources and change whatever you want, for example, the time in millis column to the time in hours.
Define the package property in "Configuration" tag to use the package to the extended class you have created.
Finally, just call the new layout from the configuration file:
<ExtHtmlLayout/>
I'm using log4j2-beta9 and want to configure it using a log4j2.xml in strict mode.
My issue is: how do I specify attributes that are not in the shipped schema file?
An Example:
<?xml version="1.0" encoding="UTF-8" ?>
<Configuration
status="DEBUG"
strict="true"
monitorInterval="5"
name="TestingAttributes"
verbose="true"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="Log4j-config.xsd">
<Properties>
</Properties>
<Appenders>
<Appender
type="Console"
name="SYSERR"
target="SYSTEM_ERR"> <!-- cvc-complex-type.3.2.2: Attribute 'target' is not allowed to appear in element 'Appender'. -->
<Layout Type="PatternLayout">
<Pattern>%date{dd.MM.yyyy HH:mm:ss,SSS} %5p %logger %m%n</Pattern>
</Layout>
<Filters>
<Filter
type="MarkerFilter"
marker="FLOW"
onMatch="DENY"
onMismatch="NEUTRAL" />
<Filter
type="MarkerFilter"
marker="EXCEPTION"
onMatch="DENY"
onMismatch="NEUTRAL" />
</Filters>
</Appender>
</Appenders>
<Loggers>
<Root level="debug">
<AppenderRef ref="SYSERR" />
</Root>
</Loggers>
</Configuration>
Notice that I want to set the appender to have the target SYSTEM_ERR but the attribute is not allowed in strict mode.
target="SYSTEM_ERR"> <!-- cvc-complex-type.3.2.2: Attribute 'target' is not allowed to appear in element 'Appender'. -->
I could always edit the Log4j-config.xsd and allow that attribute there but that would be kind of wrong also because not all appenders have a target attribute.
As searching the web didn't help me so far, I'm asking you:
Is there anything I'm missing in configuring Log4j2 in strict XML mode?
Do I have to "patch" the XMLConfiguration and the schema file and commit a change to log4j or is there another way besides not using strict mode?
Thanks in advance.
Can you ask this on the log4j-user mailing list? It could be a bug in the schema, but I suspect the schema can do with more improvements and your feedback would be valuable.
