Supports periodic health checks with configurable initial delays and execution periods, as shown in examples where checks run every 10 seconds after a 1-second delay.

Includes ready-to-use checks for HTTP requests, DNS lookups, and ping tests, reducing boilerplate for common dependencies like database connectivity with sql.DB.

Allows implementation via the Check interface or CustomCheck struct, enabling any logic, such as the lottery check example that fails based on probability.

Provides CheckListener and HealthListener interfaces for logging, metrics, or triggering actions, demonstrated with a logging listener that tracks check events.

Offers OpenCensus integration to expose metrics like check status and execution time, with configurable classifications for startup, liveness, or custom tags.
