Logging Levels
In plain terms
Severity categories for log messages.
Going deeper
Logging levels (DEBUG, INFO, WARN, ERROR) classify messages by importance so you can filter noise and focus on what matters. They rank message severity.
Under the hood
Configurable thresholds control verbosity per environment; too much DEBUG floods logs, too little hides issues.
Examples
DEBUG/INFO/WARN/ERROR, log filtering, verbosity control, structured logging.
Think of it like...
Like sorting notifications into 'info', 'warning', and 'emergency' so you focus on the urgent.
