  • 1.  Logging in Java Compute Node

    Posted Wed September 22, 2021 10:50 AM
    Hi Team,
                 I have created a message flow using java compute node, have added log4j-1.2.17.jar in build class path and shared-classes. In java compute node, I have hard coded the values logger.info("mesaage"); but in the local directory path I cannot able to see the log file.

    Please find the reference below.
    log4j.properties
    # TRACE < DEBUG < INFO < WARN < ERROR < FATAL
    log4j.rootLogger=DEBUG, toConsole, toFile
    #Console
    log4j.appender.toConsole=org.apache.log4j.ConsoleAppender
    log4j.appender.toConsole.layout=org.apache.log4j.PatternLayout
    log4j.appender.toConsole.layout.ConversionPattern=%d{HH:mm:ss} %5p [%t] - %c.%M - %m%n
    #DailyRollingFile
    log4j.appender.toFile=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.toFile.File=C:\\log\\logging.log
    log4j.appender.toFile.DatePattern='.'yyyy-MM-dd
    log4j.appender.toFile.layout=org.apache.log4j.PatternLayout
    log4j.appender.toFile.layout.ConversionPattern=%d %5p [%t] - %c.%M %L - %m%n

    Java Compute Node:
    Logger log =Logger.getLogger(ValidationMessageFlow_JavaCompute.class);
    log.info("Testing");

    Any suggestions are appreciated, Thanks in advance.

    Hello,

    check standard system logs - https://www.ibm.com/docs/en/integration-bus/10.0?topic=logs-standard-system - there should be some information about log4j initialization and processing including possible errors. Also I hope that log4j allows you to configure more verbose output using debug mode (https://logging.apache.org/log4j/2.x/faq.html#troubleshooting).
