Troubleshoot my RET Adapter

If you have trouble running an adapter, you can use the Liberator status page (http://<liberator-host>:<http-port>/status) to determine whether the adapter is up or down.

Log files

Logs help to troubleshoot an Adapter blade. More information can be found in 'Troubleshoot an Adapter blade'.

Configure logs with log4j

The log level default is set to INFO for all adapters in the RET Adapter Suite. One exception is the PricingAdapter, which is set to DEBUG level, as the logs would grow to fast for price updates.

If you want to change the log configuration of your Adapters follow these steps: 

  1. Copy the log4j.xml file from activate_blades/<Adapter>/Blade/Datasource/etc/log4j.xml into global_config/overrides/<Adapter>/etc
  2. Change the log level of the log4j.xml in global_config/overrides/<Adapter>/etc
  3. Restart the adapter ./dfw start <Adapter>

​Example log4j.xml file:
