Changing the Log Level

Fine-tuning connection pool parameters or identifying problems are reasons you may want to change the level of detail that the log displays. It is possible to set a different detail of logging for each connection pool: None, Errors, Warnings, Information and Details. The server logger should be set to no less that the Normal log level, in order to see connection pool logs. Once the project is in the production phase, Error level is the recommended level to use.
