           The `HealthCheckTimeout` setting specifies the maximum duration allowed for the health checks of the collection subsystems to complete. If a subsystem does not respond within this timeout period, it will be marked as unhealthy. This timeout value should be set carefully to ensure that transient delays do not lead to unnecessary failure detection while still allowing for timely identification of actual health issues.
