System Unresponsive is a root-cause problem that indicates that a system’s protocol endpoints are not responding to ICMP or SNMP polls and that connections to applications hosted by the system are down. Application Connectivity Monitor diagnoses the System Unresponsive problem when it receives an UnresponsiveSymptom from IP Availability Manager.

Analysis Scenarios

This section uses three different topology scenarios to illustrate how Application Connectivity Monitor (ACM) diagnoses problems. In each scenario, Application Connectivity Monitor monitors the application by regularly establishing a TCP connection with the managed application on the specified TCP port. In addition, Application Connectivity Monitor receives network and systems availability information from IP Availability Manager.

Single Application and Single TCP Check

In the following scenario, a mail server, SMTPService, is hosted by host1.example.com, as shown in Figure 1.
