Explanation of Fault

Analysis

Application Connectivity Monitor provides root-cause analysis of application failures. In addition, Application Connectivity Monitor determines the impact of network and system failures on TCP-based applications.

Application Connectivity Monitor (ACM) discovers and monitors the availability of applications that provide network services using the TCP protocol. When a TCP-based application is not available, Application Connectivity Monitor determines whether the problem is the result of a network failure or an application failure.

Topology Created by ACM

Application Connectivity Monitor automatically discovers TCP-based applications that are hosted by systems (for example, hosts, switches, routers) that are present in the topology of the ACM Domain Manager.

For each discovered application, Application Connectivity Monitor creates the following topology elements.

•Applications elements are represented by the Application class and its subclasses; which includes subclasses such as HTTPService and DatabaseServer. An application element is associated with the system it runs on through the HostedBy relationship.
