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 Update Snaplex properties dialog in SnapLogic Manager. If the log level for certain libraries needs to be changed, use these instructions the following procedure to customize the logging configuration.


Note
titleCaution

SnapLogic does not recommend changing the log file names or locations. Doing so can break the functionality that allows the viewing of logs from the SnapLogic Dashboard.

Steps

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

    Paste code macro
    cp /opt/snaplogic/etc/log4j2-jcc.xml.sample /opt/snaplogic/log4j2-jcc.xml



  2. Add 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):

    Paste code macro
    jcc.jvm_options = -Dlog4j.configurationFile=/opt/snaplogic/log4j2-jcc.xml



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

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

    You can make further configuration options per changes per your requirements.

     

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