    Hi Team


    We are using APM 10.7 on linux and the em logs are filling up very fast due to which performance is also degraded.

    Can anyone guide me through this that what could be the cause of this issue.

    your log level might be on DEBUG that why it is filling.

    Open IntrosocpeEnterpriseManager.properties  file and change following


    log4j.logger.Manager=INFO, logfile 


    change INFO to WARN

    Go to Apache's website and look at the information regarding Log4j (aka Commons Logging).

    em.log floods with : "SQLState 23505" and "duplica - CA Knowledge 


    Dear Imran:

         It depends on what the WARNING is . Are they all one message or many different ones?

    1) You can turn off all WARNINGs per above link

    2) You can attempt to resolve the situation so the WARN disappears

    3) You can open a case to get that WARNing(s) suppressed . (I would suggest 2 as the best course of action)

    public static final Level WARN
    The WARN level designates potentially harmful situations.


    public static final Level INFO
    The INFO level designates informational messages that highlight the progress of the application at coarse-grained level.


    public static final Level DEBUG
    The DEBUG Level designates fine-grained informational events that are most useful to debug an application.

    in adition to the Hallett_German suggestion consider  following.


    By default EM will write log messages to both em.log as well as IntroscopeEntepriseManager.log file for e.g

    log4j.logger.Manager=INFO, console, logfile


    you can remove this double logging by removing console from above\similar statements in IntroscopeEnterpriseManager.properties which by itself should reduce the size drastically.

    stop EM before  make changes in properties file and delete em.log before starting EM.
