----------------------------------------
Summary: Rolling logs using log4j.properties, prevents them from
showing on the UI.
Key: FLINK-9536
URL: https://issues.apache.org/jira/browse/FLINK-9536
Project: Flink
Issue Type: Bug
Components: Core
Affects Versions: 1.4.2
Reporter: SUBRAMANYA SURESH
Based on this https://issues.apache.org/jira/browse/FLINK-9471 we are forced to
keep INFO for packages like org.apache.flink.runtime.executiongraph, despite
their verbosity. An attempt to roll these logs, so that they do not fill the
disk, leads to them not showing up in the UI (JobManager logs or TaskManager
logs). The log4j.properties attempted is below.
log4j.rootLogger=WARN, SizeBasedRollingFile
log4j.logger.org.apache.flink=INFO
# Suppress the irrelevant (wrong) warnings from the Netty channel handler
log4j.logger.org.apache.flink.shaded.akka.org.jboss.netty.channel.DefaultChannelPipeline=ERROR
log4j.logger.com.myPackage=INFO, DateBasedRollingFile
log4j.appender.SizeBasedRollingFile=org.apache.log4j.RollingFileAppender
log4j.appender.SizeBasedRollingFile.File=${log.file}
log4j.appender.SizeBasedRollingFile.maxFileSize=10000
log4j.appender.SizeBasedRollingFile.maxBackupIndex=10
log4j.appender.SizeBasedRollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.SizeBasedRollingFile.layout.ConversionPattern=%d\{yyyy-MM-dd
HH:mm:ss} %-5p %-60c - %m%n
log4j.appender.DateBasedRollingFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DateBasedRollingFile.File=${log.file}-application
log4j.appender.DateBasedRollingFile.DatePattern='.'yyyy-MM-dd-HH-mm-ss
log4j.appender.DateBasedRollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.DateBasedRollingFile.layout.ConversionPattern=%d\{yyyy-MM-dd
