Manage User-Defined Applications

When possible, let the management console automatically monitor application traffic across all of your servers. If the management console requires additional information beyond what is available in the TCP packet to monitor the application, create a user-defined application and assign particular servers or a range of server IP addresses. For example, create a user-defined application to monitor:

• An application that communicates on a range of ports
• TCP-80 traffic on a particular server or servers

Use the list of system-defined applications to identify your busiest application ports and then leverage your application expertise to create user-defined applications to monitor your most heavily-trafficked, business-critical, and time-sensitive TCP applications.

When creating a user-defined application to monitor application server traffic that is currently monitored by a System application, keep in mind that after you create a user-defined application:

• The System application stops reporting on matching servers that are assigned to the user-defined application. If the management console observes application traffic on a server that is not identified by the user application’s server assignment, the management console reports the application server response time in the System application.
• The management console collects new data to report on the user-defined application. The management console does not report the existing System application data in the User application.
• Port exclusions take precedence over system- and user-defined applications. If necessary, remove the port you want from any port exclusions and then create a user-defined application.
