RET adapter log files

Log files generated by adapters created with the RET Adapter Toolkit.

Log file locations

Each RET adapter generates the following logs in the directory <dfw_root>/active_blades/<adapter_name>/DataSource/var:

ret.log

RET API specific log. Disabled by default (enable by setting ret_log_enabled=true in the file trapi-connection.properties). This file is required by RET support to investigate issues with RET-AD.

AdminAPI.log

The packet-*.log logs are in a binary format. To read them, use the logcat tool found in the servers/Liberator/bin directory.

Log4J configuration

The default log level is INFO.

To change the log level for an adapter, follow the steps below:

  1. Copy the log4j.xml file from active_blades/<Adapter>/Blade/Datasource/etc/log4j.xml into global_config/overrides/<Adapter>/etc

  2. Change the log level in the file global_config/overrides/<Adapter>/etc/log4j.xml

  3. Restart the adapter ./dfw start <Adapter>

Example log4j.xml file:
