ASP.NET Core Integration

// Startup.cs or Program.cs
services.AddSingleton<ISystemTimeProvider, SystemTimeProvider>();
services.AddSingleton<WorkflowHealthCheck>();

services.AddHealthChecks()
    .AddCheck<WorkflowHealthCheck>("workflow_health");

app.MapHealthChecks("/health");

Configuration

var healthCheck = new WorkflowHealthCheck(
    timeProvider: serviceProvider.GetRequiredService<ISystemTimeProvider>(),
    unhealthyThresholdSeconds: 30);

// Subscribe to events
smith.WorkflowStarted += (s, e) => healthCheck.RecordWorkflowExecution();
smith.WorkflowCompleted += (s, e) => healthCheck.RecordWorkflowExecution();

See Configuration Guide for complete options.

Health Status Logic

• Healthy: Workflow executed within threshold (< 30 seconds by default)
• Unhealthy: No workflow execution within threshold
• Degraded: Not currently used

Custom Health Check

public class CustomWorkflowHealthCheck : IHealthCheck
{
    private readonly IWorkflowSmith _smith;
    private DateTime _lastExecution;
    
    public async Task<HealthCheckResult> CheckHealthAsync(
        HealthCheckContext context,
        CancellationToken cancellationToken = default)
    {
        var timeSinceLastExecution = DateTime.UtcNow - _lastExecution;
        
        if (timeSinceLastExecution > TimeSpan.FromMinutes(5))
        {
            return HealthCheckResult.Unhealthy(
                $"No workflow execution in {timeSinceLastExecution.TotalMinutes:F1} minutes");
        }
        
        return HealthCheckResult.Healthy("Workflows executing normally");
    }
}
