# Enabling logging

Include Reference ID adapter events in the PingFederate server log file.

You can find more information about using Log4j in:

* [Log4j 2 logging service and configuration](https://docs.pingidentity.com/pingfederate/latest/administrators_reference_guide/pf_log4j_2_loggin_service_and_config.html) in the PingFederate documentation

* [PingFederate Log4J articles](https://support.pingidentity.com/s/global-search/%40uri#q=Log4j\&sort=relevancy\&f:@commonsource=%5BKnowledge%20Base%5D\&f:@commonproduct=%5BPingFederate%5D) in the Ping Identity Knowledge Base

## Steps

1. In your Java Virtual Machine options, set the `javax.net.debug` property to `ssl` or `all`.

2. Restart PingFederate.

3. Review the debug messages in the `<pf_install>/pingfederate/log/server.log` file.
