Basic Health Endpoint

Add a /healthz endpoint to your ASP.NET Core application:

using WorldDomination.SimpleObservability;

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

app.MapGet("/healthz", () =>
{
    var health = new HealthMetadata
    {
        ServiceName = "My API Service",
        Version = "1.0.0",
        Environment = "Production",
        Status = HealthStatus.Healthy
    };
    
    return Results.Json(health);
});

app.Run();

Advanced Example with Additional Metadata

app.MapGet("/healthz", () =>
{
    var health = new HealthMetadata
    {
        ServiceName = "My API Service",
        Version = "1.2.3",
        Environment = "Production",
        Status = HealthStatus.Healthy,
        Timestamp = DateTimeOffset.UtcNow,
        HostName = Environment.MachineName,
        Uptime = TimeSpan.FromHours(24),
        Description = "All systems operational",
        AdditionalMetadata = new Dictionary<string, string>
        {
            ["Database"] = "Connected",
            ["Cache"] = "Redis v7.0",
            ["Region"] = "us-west-2"
        }
    };
    
    return Results.Json(health);
});
