📈 Monitoring & Observability - TuskLang for C# - "See Everything"

Gain total visibility into your C# TuskLang systems!

Monitoring and observability are essential for reliability and rapid troubleshooting. This guide covers metrics, logging, tracing, alerting, and real-world monitoring strategies for TuskLang in C# environments.

👁️ Observability Philosophy

"We Don't Bow to Any King"

- Total visibility - Know everything, miss nothing - Proactive alerting - Fix issues before users notice - Unified telemetry - Metrics, logs, and traces together - Real-time insight - Instant feedback on system health - Actionable data - Metrics that drive decisions

📊 Metrics Collection

C# Metrics Tools

- Prometheus: Open-source metrics collection - App Metrics: .NET metrics library - @metrics operator: Built-in TuskLang metrics

Example: Exposing Metrics

// MetricsService.cs
using App.Metrics;
using App.Metrics.Counter;
public class MetricsService
{
    private readonly IMetrics _metrics;
    public MetricsService(IMetrics metrics) => _metrics = metrics;
    public void IncrementUserCount() => _metrics.Measure.Counter.Increment(new CounterOptions { Name = "user_count" });
}

TSK Metrics Example

config.tsk
api_response_time_ms: @metrics("api_response_time_ms", 120)

📝 Logging

Structured Logging

- Serilog: Structured logging for .NET - NLog: Flexible logging platform - @log operator: TuskLang logging (if enabled)

Example: Serilog Logging

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

🔍 Distributed Tracing

Tracing Tools

- OpenTelemetry: Distributed tracing for .NET - Jaeger: End-to-end tracing

Example: OpenTelemetry Tracing

// TracingService.cs
using OpenTelemetry.Trace;
public class TracingService
{
    private readonly Tracer _tracer;
    public TracingService(Tracer tracer) => _tracer = tracer;
    public void TraceOperation(string operation)
    {
        using var span = _tracer.StartActiveSpan(operation);
        // ... operation logic ...
    }
}

🚨 Alerting

Alerting Tools

- Prometheus Alertmanager: Alerting for Prometheus - PagerDuty: Incident response - Slack/Teams: ChatOps alerts

Example: Alerting on Metrics

- Set up Prometheus alert rules for error rates, latency, etc. - Integrate with PagerDuty or Slack for notifications

🛠️ Real-World Monitoring Scenarios

- API latency spikes: Use @metrics and distributed tracing - Error surges: Structured logging and alerting - Resource exhaustion: Monitor CPU/memory with Prometheus - Business KPIs: Custom metrics in TSK and C#

🧩 Best Practices

- Instrument everything - Use structured logs - Correlate logs, metrics, and traces - Set actionable alerts - Review dashboards regularly

🏁 You're Ready!

You can now: - Monitor C# TuskLang systems end-to-end - Collect and analyze metrics - Log and trace with best-in-class tools - Set up actionable alerts
