📝 Logging - TuskLang for C# - "Log Everything"

Master structured logging for your C# TuskLang applications!

Logging is essential for debugging, monitoring, and auditing. This guide covers structured logging, log levels, log aggregation, and real-world logging strategies for TuskLang in C# environments.

📋 Logging Philosophy

"We Don't Bow to Any King"

- Log everything - Every action, every decision - Structured data - JSON logs for easy parsing - Context matters - Include relevant metadata - Performance first - Async logging, no blocking - Searchable logs - Make logs easy to find and analyze

🏗️ Structured Logging

C# Logging Tools

- Serilog: Structured logging for .NET - NLog: Flexible logging platform - Microsoft.Extensions.Logging: .NET Core logging

Example: Serilog Configuration

// LoggingConfiguration.cs
using Serilog;
Log.Logger = new LoggerConfiguration()
    .WriteTo.Console()
    .WriteTo.File("logs/app-.txt", rollingInterval: RollingInterval.Day)
    .CreateLogger();

📊 Log Levels

Example: Using Different Log Levels

// LoggingService.cs
using Serilog;
public class LoggingService
{
    private readonly ILogger _logger;
    public LoggingService(ILogger logger) => _logger = logger;
    
    public void LogDebug(string message) => _logger.Debug(message);
    public void LogInfo(string message) => _logger.Information(message);
    public void LogWarning(string message) => _logger.Warning(message);
    public void LogError(string message, Exception ex) => _logger.Error(ex, message);
    public void LogFatal(string message, Exception ex) => _logger.Fatal(ex, message);
}

🔍 Log Aggregation

Example: Sending Logs to ELK Stack

// ElkLogging.cs
using Serilog;
using Serilog.Sinks.Elasticsearch;
Log.Logger = new LoggerConfiguration()
    .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri("http://localhost:9200"))
    {
        IndexFormat = "logs-{0:yyyy.MM.dd}"
    })
    .CreateLogger();

🛠️ Real-World Logging Scenarios

- API requests: Log request/response with correlation IDs - Database operations: Log queries and execution times - Configuration changes: Log when configs are loaded/modified - User actions: Log user interactions for audit trails

🧩 Best Practices

- Use structured logging (JSON) - Include correlation IDs - Log at appropriate levels - Don't log sensitive data - Use async logging for performance

🏁 You're Ready!

You can now: - Implement structured logging in C# TuskLang apps - Configure log aggregation and analysis - Use logs for debugging and monitoring
