Developing custom Snaps might require changing the built-in logging configuration of the Snaplex node. Most configuration changes related to Log settings (such as the retention level or file size) can be done through the /wiki/spaces/DRWIP/pages/2599518351 Updating Snaplexes dialog in SnapLogic Manager. If the log level for certain libraries needs to be changed, use the following procedure to customize the logging configuration.

...

  1. Copy the configuration file to a location outside of the etc directory:

    Code Block
    cp /opt/snaplogic/etc/log4j2-jcc.xml.sample /opt/snaplogic/log4j2-jcc.xml

  2. To enable the custom logging configuration, add a configuration property in the global . properties file   (or in the .slpropz configuration file from the Snaplex properties file):

    Code Block
    jcc.jvm_options = -Dlog4j.configurationFile=/opt/snaplogic/log4j2-jcc.xml

  3. Apply the changes in the configuration file. For example, to disable logging for a Parquet library, add the following:

    Code Block
    <Logger name="org.apache.parquet" level="error" includeLocation="true" additivity="false">
  <AppenderRef ref="JCCMAINJSON"/>
  <AppenderRef ref="JCCERRORJSON"/>
</Logger>

    You can make further logging configuration changes per your requirements.

     

  4. Apply these changes to all the nodes in the Snaplex, and restart the Java Component Container (JCC) processes.
