Monitoring a production environment for the stevedunn/pacmanblazor project involves utilizing various techniques to ensure that the application is running smoothly and efficiently. The following steps provide a comprehensive approach to monitoring the application in production.

1. Application Insights Integration

Integrating Application Insights allows for detailed telemetry data collection.

Step 1: Install Application Insights SDK

Add the following NuGet package to your Blazor project:

dotnet add package Microsoft.ApplicationInsights.AspNetCore

Step 2: Configure Application Insights

In the Startup.cs file, configure Application Insights in the ConfigureServices method:

public void ConfigureServices(IServiceCollection services)
{
    services.AddApplicationInsightsTelemetry(Configuration["ApplicationInsights:InstrumentationKey"]);
    // Other service configurations
}

Ensure the Instrumentation Key is defined in appsettings.json:

{
  "ApplicationInsights": {
    "InstrumentationKey": "your-instrumentation-key"
  }
}

Step 3: Telemetry Data Collection

To track custom events, metrics, or exceptions, inject the TelemetryClient and use it within your components or services:

public class MyComponent : ComponentBase
{
    private readonly TelemetryClient _telemetryClient;

    public MyComponent(TelemetryClient telemetryClient)
    {
        _telemetryClient = telemetryClient;
    }

    protected override void OnInitialized()
    {
        _telemetryClient.TrackEvent("ComponentInitialized");
        // Additional logic
    }
}

2. Logging

Utilizing logging frameworks can also provide crucial insights into your application’s performance.

Step 1: Setup Logging

For instance, in the Startup.cs, configure logging as follows:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILogger<Startup> logger)
{
    logger.LogInformation("Application Starting");

    // Other app configurations
}

Step 2: Implementing Logging in Components

Within your components, use dependency injection to log relevant information:

public class GameComponent : ComponentBase
{
    private readonly ILogger<GameComponent> _logger;

    public GameComponent(ILogger<GameComponent> logger)
    {
        _logger = logger;
    }

    private void OnGameStart()
    {
        _logger.LogInformation("Game Started at {Time}", DateTime.UtcNow);
        // Game logic here
    }
}

3. Health Checks

Implementing health checks helps monitor the status of various application components.

Step 1: Register Health Checks

Add health checks in the Startup.cs:

public void ConfigureServices(IServiceCollection services)
{
    services.AddHealthChecks();
    // Other service configurations
}

Step 2: Health Check Endpoint

Make sure to expose a health check endpoint:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.UseHealthChecks("/health");
    // Other app configurations
}

Step 3: Custom Health Check

You can implement a custom health check by creating a class that implements IHealthCheck:

public class DatabaseHealthCheck : IHealthCheck
{
    public Task<HealthCheckResult> CheckAsync(HealthCheckContext context, CancellationToken cancellationToken = default)
    {
        bool isHealthy = // Logic to check database connection
        return Task.FromResult(isHealthy ? HealthCheckResult.Healthy() : HealthCheckResult.Unhealthy());
    }
}

4. Performance Monitoring

For performance monitoring, utilizing tools that analyze application metrics such as response times, server resources, and user engagement can be essential.

Integrate performance metrics tracking utilizing Application Insights or custom logging to gather necessary data.

Example of Tracking Performance

public class PerformanceMonitoringService
{
    private readonly TelemetryClient _telemetryClient;
    
    public PerformanceMonitoringService(TelemetryClient telemetryClient)
    {
        _telemetryClient = telemetryClient;
    }

    public void TrackPerformance(TimeSpan duration, string operation)
    {
        _telemetryClient.TrackMetric("OperationDuration", duration.TotalMilliseconds, new Dictionary<string, string>
        {
            { "OperationName", operation }
        });
    }
}
