Logging
Logging is the process of recording events, messages, or other information during the execution of an application. It typically captures data like application state, errors, warnings, or performance metrics and writes them to a file, console, database, or remote logging system for later analysis.
Logging provides critical benefits for application development and maintenance:
Debugging and Issue Diagnosis Logs help identify and fix bugs by providing detailed information about application execution.
Monitoring Application Behavior Logs enable developers and system administrators to monitor how an application behaves in different environments (development, testing, production).
Audit and Compliance Logs can serve as a record of transactions, access, and changes for audit and compliance purposes.
Performance Analysis Logs can be used to track performance bottlenecks and optimize resource usage.
User Support and Error Tracking Logs help in understanding user-reported issues and correlating them with system behavior.
Log Levels Logs are categorized based on their severity or importance:
Trace: Detailed information for diagnosing specific parts of an application.
Debug: Information for developers to debug the system.
Info: General events indicating normal operation.
Warning: Potential issues that may need attention.
Error: Runtime errors that need to be addressed.
Critical: Severe issues causing application failures.
