How to Create Property Groups and Properties

Throughout this tutorial, you will want to limit the activities of NerveCenter to a particular set of nodes. This will reduce the impact of the exercises on the network as well as make the information more manageable.

This scenario includes the following three activities:

  1. Creating a New Property Group
  2. Creating a New Property
  3. Assigning a Property Group to a Set of Nodes

Creating a New Property Group

This first activity will step you through the process of creating a unique property group called CriticalDevices.

 
  To create a property group:

  1. Open the NerveCenter Client and connect to the appropriate NerveCenter Server.
  2. From the Admin menu, choose Property Group List.

    PropButton

    NerveCenter displays the Property Group List window.

    PropList

    The Property Group List window contains summary information about all property groups and properties in the NerveCenter database for the active server. From this window you can open existing property groups or create new ones.

  3. Scroll through the Property Group list until you see the property group called Mib-II.
  4. Select Mib-II.

    The properties belonging to the Mib-II property group display to the right in the Property list.

    Rather than create an entire new set of properties for our new property group, we will use the properties already present.

  5. In the New Property Group field, type the name of your new property group CriticalDevices.
  6. Under the New Property Group field, select Copy.

    CriticalDevices now appears in the list of property groups and is highlighted. Notice also the Property list to the right contains a list of properties.

    The Copy button creates a new property group that contains the same properties as the selected group. In this case, NerveCenter created a new property group called CriticalDevices containing the same properties as the group Mib-II.

  7. Select Save.

Now that you have created a new property group, it is time to create a new property that will enable NerveCenter to target just those devices that interest you.

What is a property?

In this next activity you will be creating a property.

A property is a string. This string can be:

  • The name of a MIB base object
  • A user-defined string

This string determines (in part) if NerveCenter will interact with a particular node. A property group is a named container for properties.
