Assigning a Property Group to a Set of Nodes

This next activity will step you through the process of isolating the devices you will be monitoring throughout the rest of this book. You will achieve this by assigning the CriticalDevices property group to a particular set of nodes.

In our example network we would want to isolate the critical routers. For this tutorial, you will be isolating three of your department's managed workstations.

 
  To assign a property group to a set of nodes:

1. Identify at least three of your department's managed workstations that you know are running SNMP agents. Write their names on the following lines:

   

   

   

If you have questions about which devices to use, see Before You Begin on page 2.

1. From the Admin menu, choose Node List.

   

   NerveCenter displays the Node List window.

   

   The Node List window lists all nodes in the NerveCenter database. This window provides the tools for identifying nodes of interest, changing their configuration, or opening a node's associated definition window.

2. Scroll through the node list until you see one of the devices you wish to monitor in these exercises. After highlighting that device, select Open.

   NerveCenter displays that device's Node Definition window.

   

The Node Definition window enables you to change the various elements of a managed device, such as its name, IP address, community string, deletion strategy, and property group.

1. In the Property Group list, select the CriticalDevices property group.
2. Select Save.
3. To close the window, select Cancel.
4. In the Node List window, hold down the Ctrl key and select the remainder of the devices you wish to monitor.

   Each node that is selected is highlighted. If you inadvertently select an unwanted node, select it again so that it is no longer highlighted.

5. Right-click one of the highlighted devices and select Property Group.

   The Property Group window displays.

   

   In the Property Group window, select the CriticalDevices property group.

6. Select Save.
7. In the Node List window, select Close.

You have just assigned the unique property group CriticalDevices to a particular set of nodes. This will allow you to isolate only relevant devices as you work through the rest of this book.

Now you are ready to begin using NerveCenter. Chapter 3, How to Use Polls will illustrate how to use NerveCenter to proactively monitor your CriticalDevices nodes.
