To monitor the health of specific aspects of our application, we'll be creating an instance of the IHealthCheck middleware. This middleware is used to define the operations that are necessary for determining the relative health of your system. For our purposes, we'll want to define a health-check that confirms that the response time for our dependent data service is below two seconds. Once that threshold has been hit, we'll consider the system to be degraded. This will allow our watchdog to notify us that a restart may be necessary. However, if the service response time increases to five seconds, we'll consider it unhealthy, notifying our watchdog to initiate a reset.
