Subject: setting up log4j2 for Kafka Provider
Good Afternoon,
Am looking to control log4j2 output produced by Kafka...but am having a little
difficultly getting this to work as expected.
During the kafka producer startup I've added this command:
-Dlog4j2.configurationFile=/<whatever>/kafka/producers/log4j2.properties
I've created a log4j2.properties file as follows:
# Root Logger
rootLogger=INFO, STDERR
# Direct log messages to stderr
appender.console.type = Console
appender.console.name = STDERR
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t]
%C{1} - %msg%n
Yet, when I look at STDERR am not seeing the desired messages. Do I need to
configure slf4j instead or in conjunction? Anything I'm possibly doing wrong?
Anyone with experience on customizing kafka message logging, will to chime in?
Thank You,
--Alex
