Explanation of Fault Analysis

Application elements are visible in the Topology Browser and

Applications Map views of the Global Console when attached to the

Global Manager.

•TCPConnectivityCheck elements represent the TCP connection initiated by the ACM Domain Manager to check the availability of monitored applications. Application Connectivity Monitor uses the symptoms reported by the TCP checks to perform its analysis.

TCPConnectivityCheck elements may be listed in the Notification Log view or Codebook tab of the Notification Properties dialog of the Global Console when attached to the Global Manager. TCPConnectivityCheck elements are listed when an event occurs.

Faults Diagnosed by ACM

Application Connectivity Monitor notifies the following problems for application elements.

D o w n

Down is a root-cause problem that indicates that the application is not running; either because the process has died or stopped. Application Connectivity Monitor diagnoses the Down problem when all TCP checks return TimedOutSymptom events.

M a l f u n c t i o n

Malfunction is a root-cause problem that indicates that the application is not working properly. The application may be providing service to some users but not other users or it may not be providing the correct response. Application Connectivity Monitor diagnoses the Malfunction problem when one or more, but not all, TCP checks return TimedOutSymptoms events. In addition, one or more TCP checks may return the SlowSymptom event.

D e g r a d e d

Degraded is a root-cause problem that indicates that the application is running slowly. Application Connectivity Monitor diagnoses the Degraded problem when a TCP check returns the SlowSymptom event.
