Replaced the fixed 3x interval multiplier with an adaptive threshold
based on the configured interval duration. Health states (`Healthy`,
`Degraded`, `Unhealthy`) were redefined to reflect this change.
- Adaptive multiplier: 3x for fast intervals (<10s), 1.5x for slower
intervals (≥10s), ensuring faster problem detection for longer
intervals and tolerance for jitter in shorter intervals.
- Updated `CheckHealthAsync` to calculate `maxAllowedDelay` using the
adaptive multiplier.
- Added `Multiplier` and `MaxAllowedDelay` to diagnostic data for
better monitoring and debugging.
- Improved documentation and comments to explain the new logic.
Added detailed XML documentation across multiple files to enhance
code maintainability and readability. Key updates include:
- Documented `AllowAllDashboardAuthorizationFilter` to clarify
its development-only usage.
- Added comments to `DtoExtensions` for Hangfire job ID generation
and DTO-to-command conversion methods.
- Enhanced `HealthCheckHtmlGenerator` with detailed descriptions
of HTML generation methods and utility functions.
- Documented `DependencyInjection` and `ProfileWorkerOptionsValidator`
to explain service registration and configuration validation.
- Updated `ProfileCache` with comments on thread-safe operations.
- Added documentation to `ProfileWork` for profile synchronization
logic and execution flow.
- Enhanced `ProfileWorker` with health check logic and background
service execution details.
- Documented `ProfileWorkerOptions` configuration properties.
These changes aim to improve developer understanding and ensure
best practices are followed in production environments.
- ProfileWork.cs: Business logic for DB-to-Hangfire sync
- Fetches active profiles from database via MediatR
- Registers/updates Hangfire recurring jobs with local timezone
- Removes stale jobs (deleted from DB)
- O(n) performance optimization using HashSet for lookups
- Uses ProfileWorker's stopping token for graceful shutdown
Job lifecycle:
- ProfileWorker stops → All running jobs cancelled via token closure
- Jobs use RecurringJobOptions with TimeZoneInfo.Local
- Automatic retry support via Hangfire [AutomaticRetry] attribute
- Create ProfileWorker namespace with 4 separate components
- ProfileWorker.cs: BackgroundService orchestrator with IOptions support
- ProfileWorkerOptions.cs: Configuration model with validation
- ProfileCache.cs: Thread-safe cache using composition pattern
- DependencyInjection.cs: Service registration with IValidateOptions
Benefits:
- Separation of concerns (orchestration, config, state, DI)
- IOptions pattern for appsettings.json configuration
- Startup validation for configuration errors
- Better testability and maintainability
