Increasing log verbosity

The Sqreen Ruby agent can log messages to a text file. These messages contain warnings about possible abnormal behavior and describe some actions the agent is executing.

Two values in the sqreen.yml configuration control the logging: log_level and log_location (or the corresponding environment variables SQREEN_LOG_LEVEL and SQREEN_LOG_LOCATION). In order to log more information, you can change log_level to info or even debug. The default is warn, in order to avoid the log file getting too large and the synchronious writing to the file slowing down the application. The info level is reasonably verbose for production environments, but debug should only be used for short periods of time due to the amount of data it generates.
