The analysis of Mail Server Down is independent of the analysis of other applications running on host2.example.com.

W e b S e r v e r D o w n

A Down problem indicates that the application is not responding to connectivity polls from Application Connectivity Monitor.

To diagnose Web Server Down in this scenario, Application Connectivity Monitor observes that TCP checks sent to HTTPService time out, resulting in TimedOutSymptom events.

Figure 6 shows the Notification Properties for the HTTPService Down problem. Application Connectivity Monitor diagnoses the Down problem because it observes the TimedOutSymptom event in response to a TCP check.
