Customization Examples for Appenders
This section lists the customization code that was used for some appenders using previous Log4j version and the recommended customizations for these appenders for Log4j 2.0 compatibility.
• Console appender
Log4j 1.2 Usage
Log4j 2.0 Usage
wt.log4j.jmx.ConsoleAppender
# Define stdout appender, which sends log events to stdout
log4j.appender.stdout=wt.log4j.jmx.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%-5p : %c %X{user} - %m%n
Console
# Define stdout appender, which sends log events to stdout
appender.stdout.type = Console
appender.stdout.name = stdout
appender.stdout.follow = false
appender.stdout.layout.type = PatternLayout
appender.stdout.layout.alwaysWriteExceptions = false
appender.stdout.layout.pattern = %-5p : %c %X{user} - %m%ex%n
• RollingFile appender
Log4j 1.2 Usage
Log4j 2.0 Usage
wt.log4j.jmx.DailyRollingFileAppender
# Define methodServerLogFile appender, which sends log events to a file
log4j.appender.methodServerLogFile=wt.log4j.jmx.DailyRollingFileAppender
log4j.appender.methodServerLogFile.File=${wt.logs.dir}/${wt.manager.serviceName}-${wt.jvm.startTime.formatted.short}-${wt.jvm.id}-log4j.log
log4j.appender.methodServerLogFile.DatePattern='.'yyyy-MM-dd
log4j.appender.methodServerLogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.methodServerLogFile.layout.ConversionPattern=%d{ISO8601} %-5p [%t] %c %X{user} - %m%n
RollingFile
# Define methodServerLogFile appender, which sends log events to a file
appender.methodServerLogFile.type = RollingFile
appender.methodServerLogFile.name = methodServerLogFile
appender.methodServerLogFile.createOnDemand = true
appender.methodServerLogFile.fileName = ${sys:wt.logs.dir}/${sys:wt.manager.serviceName}-${sys:wt.jvm.startTime.formatted.short}-${sys:wt.jvm.id}-log4j.log
appender.methodServerLogFile.filePattern = ${sys:wt.logs.dir}/${sys:wt.manager.serviceName}-${sys:wt.jvm.startTime.formatted.short}-${sys:wt.jvm.id}-log4j.log.%d{yyyy-MM-dd}_%i
appender.methodServerLogFile.layout.type = PatternLayout
appender.methodServerLogFile.layout.alwaysWriteExceptions = false
appender.methodServerLogFile.layout.pattern = %d{yyyy-MM-dd HH:mm:ss,SSS} %-5p [%t] %c %X{user} - %m%ex%n
appender.methodServerLogFile.policies.type = Policies
appender.methodServerLogFile.policies.time.type = TimeBasedTriggeringPolicy
appender.methodServerLogFile.policies.time.interval = 1
appender.methodServerLogFile.policies.time.modulate = true
appender.methodServerLogFile.policies.size.type = SizeBasedTriggeringPolicy
appender.methodServerLogFile.policies.size.size=9MB
appender.methodServerLogFile.strategy.type = DefaultRolloverStrategy
appender.methodServerLogFile.strategy.max = 2147483647
For date patterns in log4jMethodServer.properties, see the example:
appender.methodServerLogFile.layout.pattern = %d{​​​​​yyyy-MM-dd HH:mm:ss,SSS}​​​​​{​​​​​${​​​​​timeZone}​​​​​}​​​​​ %-5p [%t] %c %X{​​​​​user}​​​​​ - %m%ex%n
For RollingFileAppender rollover policies, see the example:
appender.methodServerLogFile.filePattern = ${sys:wt.logs.dir}/${sys:wt.manager.serviceName}-${sys:wt.jvm.startTime.formatted.short}-${sys:wt.jvm.id}-log4j.log.%d{yyyy-MM-dd}_%i
appender.methodServerLogFile.policies.type = Policies
appender.methodServerLogFile.policies.midnight.type = SizeBasedMidnightTriggeringPolicy
appender.methodServerLogFile.policies.midnight.size=9MB
appender.methodServerLogFile.strategy.type = DefaultRolloverStrategy
appender.methodServerLogFile.strategy.max = 2147483647
${timeZone} parameter should be used for date pattern in log4jMethodServer.properties only. It is mandatory to have the %d{yyyy-MM-dd}_%i file pattern for RolingFile appender.
• AsyncJDBCAppender appender
Log4j 1.2 Usage
Log4j 2.0 Usage
wt.log4j.jmx.AsyncJDBCAppender
# Define MiscLogEvents appender, which sends log events (of sufficiently high severity) to the database
log4j.appender.MiscLogEvents=wt.log4j.jmx.AsyncJDBCAppender
log4j.appender.MiscLogEvents.BatchSize=200
log4j.appender.MiscLogEvents.IncludeMDC=true
log4j.appender.MiscLogEvents.threshold=WARN
# Throttle logging of exception traces to the database (adjust threshold as needed)
log4j.appender.MiscLogEvents.ThrowableElideThreshold=15
wt.log4j.jmx.AsyncJDBCAppender
# Define MiscLogEvents appender, which sends log events (of sufficiently high severity) to the database
appender.MiscLogEvents.name=MiscLogEvents
appender.MiscLogEvents.type=AsyncJDBCAppender
appender.MiscLogEvents.BatchSize=200
appender.MiscLogEvents.IncludeMDC=true
appender.MiscLogEvents.filter.threshold.type=ThresholdFilter
appender.MiscLogEvents.filter.threshold.level=WARN
# Throttle logging of exception traces to the database (adjust threshold as needed)
appender.MiscLogEvents.ThrowableElideThreshold=15
• IncomingRmiStatsAppender appender
Log4j 1.2 Usage
Log4j 2.0 Usage
wt.log4j.jmx.IncomingRmiStatsAppender
# Configure IncomingRmiStats appender
# Collects RMI statistics for viewing with wt.rmi.jmx.IncomingRmiStatsMonitor MBean; must instantiate this MBean (via MBean Loader) to access results
log4j.appender.IncomingRmiStats=wt.rmi.jmx.IncomingRmiStatsAppender
# Disable IncomingRmiStats appender by default; set threshold to INFO to enable
log4j.appender.IncomingRmiStats.threshold=WARN
wt.log4j.jmx.IncomingRmiStatsAppender

# Configure IncomingRmiStats appender
# Collects RMI statistics for viewing with wt.rmi.jmx.IncomingRmiStatsMonitor MBean; must instantiate this MBean (via MBean Loader) to access results
appender.IncomingRmiStats.name=IncomingRmiStats
appender.IncomingRmiStats.type=IncomingRmiStatsAppender
# Disable IncomingRmiStats appender by default; set threshold to INFO to enable
appender.IncomingRmiStats.filter.threshold.type=ThresholdFilter
appender.IncomingRmiStats.filter.threshold.level=WARN
