You might want to change the logging levels in the Neo4j client (driver/browser) at times to capture more or less information about the connection and query responses.

In your application logs, you'll find one of the following log levels for entries listed from least urgent to most urgent.

• DEBUG - The most verbose of all the logging levels. This level should only be used when actively debugging an issue. 
• INFO - Normal message that something of interest happened in the application. Can be ignored almost all of the time. 
• WARN - A non-fatal event took place. Functionality has not been lost and work is continuing.
• ERROR - An event took place that breaks some core functionality. Work may or may not continue.
• FATAL - An event occurs that brings the application to a halt. No work continues.
