A Host Unresponsive problem indicates that a network or system problem is affecting the system on which the managed application is running.

To diagnose Host Unresponsive in this scenario, Application Connectivity Monitor must receive an UnresponsiveSymptom from IP Availability Manager. Application Connectivity Monitor may also observe TimedOutSymptom or SlowSymptom events for TCP checks sent to the ports used by HTTPService.

A Degraded problem indicates that the application is not performing as expected. The application is responding to TCP checks, but not within the expected time period.

To diagnose Degraded in this scenario, Application Connectivity Monitor observes a SlowSymptom event for one of the monitored ports of HTTPService.

Two Applications on a Single System

In the following scenario, two applications, HTTPService and SMTPService, are running on the same system, host2.example.com. Application Connectivity Monitor monitors each application with a different TCP check.
