Explanation of Fault Analysis

W e b S e r v e r M a l f u n c t i o n

A Malfunction problem indicates that the application is not functioning properly because it responds correctly to certain connection requests and incorrectly to other connection requests.

To diagnose Malfunction in this scenario, Application Connectivity Monitor observes TimedOutSymptom events for TCP checks sent to one of the ports on HTTPService. In addition, ACM may observe SlowSymptom events for TCP checks sent to the ports used by webserver.example.com.

Figure 4 shows the Notification Properties for the HTTPService Malfunction problem. Application Connectivity Monitor diagnosed the Malfunction problem after observing a TimedOutSymptom event for a TCP check sent to one of the ports of the Web server. Because one port is still responsive, Application Connectivity Monitor does not diagnose this as a Down problem.
