Describe the bug

The HealthConfig struct lacks the StartInterval field, which is crucial for defining the frequency of health checks during the initial start period of an application. The absence of this field means that the health checks may not run at the intended intervals during startup, potentially affecting the system's ability to monitor and respond to early issues effectively.

Steps to Reproduce

Navigate to the definition of the HealthConfig struct in the codebase.
Note the absence of the StartInterval field, which should allow setting the interval at which health checks are performed during the application's start period.
