This chapter describes the tasks you can perform to create, monitor, and configure diagnostic system modules. A diagnostic system module is a software component that you configure to monitor an aspect of a server or server resource. This chapter also describes the tasks you can perform to create, monitor, and configure policies and actions.

This chapter includes the following sections:

Create diagnostic system modules

To create a new diagnostic system module:

  1. From the WebLogic Domain menu, select Diagnostics, then select Diagnostic Modules.

    The Diagnostic Modules table displays information about the diagnostic system modules that have been configured in the current WebLogic Server domain.

  2. Click Create.
  3. On the Create Diagnostic Modules page, define the properties for this new diagnostic system module.

    • Name: enter a name for this diagnostic system module.

    • Scope: select the scope for this diagnostic system module from the menu.

    • Description: enter a description to help you identify this diagnostic system module.

    • Use a Built-in Diagnostic System Module as a Template: select this checkbox to use a built-in diagnostic system module as the template for this new diagnostic system module.

      Using a built-in diagnostic system module as a template provides a simple, quick, and efficient way to create a diagnostic system module. You select the particular built-in module you want to use as a template, then change the configuration of the built-in module as desired.

    • Built-In Diagnostic System Module: if you are using a built-in diagnostic system module as a template, select one of the three built-in diagnostic system modules from this menu (Low, Medium, or High).
