Studio Logging

Studio logging helps you to monitor and troubleshoot your Studio application.

About logging in Studio
Studio uses the Apache Log4j logging utility.
About the Log4j configuration XML files
The primary log configuration is managed in portal-log4j.xml, which is packed inside the portal application file WEB-INF/lib/portal-impl.jar.
About the main Studio log file
For Studio, the main log file (bdd-studio.log) contains all of the log messages.
About the metrics log file
Studio captures metrics logging, including all log entries from the com.endeca.portal.instrumentation classes.
Configuring the amount of metrics data to record
To configure the metrics you want to include, you use a setting in portal-ext.properties. This setting applies to both the metrics log file and the Performance Metrics page.
About the Studio client log file
The Studio client log file collects client-side logging information. In particular, Studio logs JavaScript errors in this file.
Adjusting Studio logging levels
For debugging purposes in a development environment, you can dynamically adjust logging levels for any class hierarchy.
Using the Performance Metrics page to monitor query performance
The Performance Metrics page on the Control Panel displays information about component and Dgraph Gateway query performance.
