The system conducts periodic health checks on the components of the instance, including various aspects of any input or output connections configured in deployed flows.
By default, these health checks are performed every 30 seconds, but you can change this interval by editing the value of the HEALTH_CHECK_INTERVAL ".env" file variable. The interval applies to all components, so it is not possible to set one interval for connections and another for the rest of the system. To learn more about this value, see Health Check Interval.
