Objectives

This exercise is a complex example of using Dynamic Model. This example enhances the following Domain Managers:

• Network-Resource Manager

• IP-Perspective Manager

• IP-Analysis Manager

• Global Manager

  The purpose of the exercise includes:

• Polling for a new attribute.

• Generating an event based on the value of the attribute.

• Forwarding the new event to a Global Manager so that it can be displayed as a notification.

  Note:

  This exercise should be performed on test versions of a Broker, Network-Resource Manager, IP-Perspective Manager, IP-Analysis Manager, and Global Manager. Before starting this exercise, back up the repository on the test Managers.

  This exercise includes the following tasks:

• Determine the instrumentation class that will be refined to poll for the new attribute.

• Create and compile a dynamic model file:

  • Define an additional MIB variable that can be polled by the Network-Resource Manager.

  • Define a setting class for the new attribute.

  • Refine an instrumentation class that will define the MIB OID to poll.

• Subscribe to the event in the Network-Resource Manager.

• Add a new threshold setting to adapter-setting.asl.

• Add the polled event to the Global Manager.

• Load the dynamic model into the Network-Resource Manager, IP-Perspective Manager, and the IP-Analysis Manager.

• Set up topology sources.

• Discover an instance of the Router class.

• Verify variable in Polling and Threshold dialog box.

• Poll the values of the new attributes in real-time.

• Generate an event based on the values of this polled attribute.

• Have the Global Manager subscribe to and display notifications associated with the event based on the value of this polled attribute.
