Sending e-mail notifications with WLDF

The WebLogic Diagnostic Framework (WLDF) is a set of functionalities to monitor, collect, and analyze runtime counters, metrics, and statistical and diagnostic data from various WebLogic Server components. The metrics can be gathered from the JRockit JVM, the WebLogic domain, the WebLogic clusters, Managed Servers, applications, and every component that exposes data through MBeans.

WebLogic Administrators can include active monitoring in production environments with WLDF. It is possible to configure WebLogic to send e-mail alerts when certain conditions and metrics are reached.

In this recipe, the WebLogic domain will be configured to send e-mail alerts when the WebLogic thread pool from a Managed Server has queued requests waiting to be processed.

Getting ready

A mail session called EmailAlertMailSession and a diagnostic module named EmailAlertModule will be created using the Administration Console, so make sure the Administration Server is running.
